About

This workshop provides a foundation for getting started with creating, configuring, and hosting web maps with the QGIS plugin QGIS2Web and GitHub. It is not meant to give a comprehensive introduction to all applications used, such as QGIS, Leaflet, and Atom. Familiarity with editing html documents in a text editor and some foundational experience with geospatial data, GIS, and GitHub may be helpful if following along.

This workshop will not cover how to create the geospatial data or host images in web maps. However, some bonus sections at the bottom of this document contains basic information about image processing.

Why use Leaflet?

Using a free and open-source tool that gives access to source code ensures that you retain access and ownership of the code and data. Many content management system plugins, web map creation platforms (Esri, Carto), and/or freemium services may not allow you to fully retain ownership, often have data limits and restrictions, can use your map and data in any way per any license agreement, can make it difficult to extract the source code and data, may change pricing structures at any time, or delete your data without notice.

You can choose to host a Leaflet map on any platform, but this tutorial uses GitHub. GitHub is free and easy to use for sharing code, working on digital projects, and hosting html documents and images, which this tutorial makes use of.

Software and accounts

This tutorial was made using Mac iOS Mojave v 10.14.5. The following software and accounts are used and are required before going further:

Fork this repository and clone to GitHub Desktop

  1. Go to github.com and login. Create a new account if needed.

  2. Go the repository for this workshop: github.com/taylorhixson/WF

  3. In the top right of the repository, click Fork.

Image is a screenshot of the top right of the repository in GitHub showing the Watch, Star, and Fork options with Fork outlined in red

  1. Once the repository is forked, it will show up in your repositories. If needed click your profile avatar in the top right and choose Your repositories. If the repository was forked correctly, a repository called WF should appear.

  2. In the WF repository, click Clone or download, and from that popup, choose Open in Desktop. Make sure the link shows your GitHub username NOT the workshop creator’s username. The below screenshot shows the creator’s because the screenshot was taken from her account.

Image is a screenshot of the middle right of the repository options in GitHub showing the Create new file, Upload files, Find files, and Clone or download options with Clone or download outlined in red

If the browser prompts you, choose Open GitHub Desktop.

Image is a screenshot of a browser prompt asking "Open GitHub Desktop with options to cancel or open."

  1. Navigate to where you save git repositories. If this is your first one or you don’t have a primary git folder, just use the default.

Create gh-pages

  1. Once the repository is cloned, click Current Branch, which is between Current Repository and Push origin. The current branch probably says master.

Image is a screenshot showing the Current Branch button.

  1. Click New Branch.

Image is a screenshot highlighting the New Branch button.

  1. Name the new branch gh-pages. The branch must be named gh-pages. Naming a branch gh-pages tells GitHub that the branch should function as GitHub Pages, GitHub’s hosting services.

Image is a screenshot highlighting the new branch name gh-pages.

  1. Click Create Branch.

  2. Click Publish branch.

  3. Once you publish something to the gh-pages branch, you can see it at the branch’s GitHub Pages site at YourGitHubAccount.github.io/gitRepositoryName/webapp.

    • YourGitHubAccount = replace with your GitHub account named
    • .github.io/ = keep as is
    • gitRepositoryName = input the git repository name such as 2019_oslo
    • webapp = this is the where an index.html file or something to display online lives. In this workshop it is the folder that originally had the long qgis2web title and was changed to webapp in the section Editing qgis2web index.html file
    • For example a gh-pages link would like taylorhixson.github.io/WF/webapp

      Working with QGIS

      Note: If downloading QGIS3 for the first time on a Mac, watch this video. It is not a one-click install on Mac.

Saving a project

  1. Open QGIS. If you do not know where it is, search for it in Spotlight. The icon is a green Q.

  2. Once open, use command + S, click the floppy disc icon in the top left of QGIS, OR click File>Save.

  3. Navigate to the git repository for this project.

  4. Name the QGIS project file.

  5. Make sure the file type is .qgz.

    Image is a screenshot showing the location and file type for saving QGIS projects

  6. While working in QGIS, periodically save the project. Saving the project makes sure layer styles and all other project properties, including qgis2web Leaflet properties, are saved when the project is closed or when it is shared with others.

Installing QGIS Plugins

  1. Open QGIS.

  2. Click Plugins from the top menu.

    Image is a screenshot highlighting the Plugins option in the top menu

  3. Click Manage and Install Plugins….

    Image is a screenshot showing the manage and install plugins options

  4. Make sure All is selected from the left side of the popup window, and in the search box, type qgis2web. Note: an internet connection is required to search for and install plugins this way.

    Image is a screenshot highlighting searching for plugins

  5. Select the result qgis2web so that the information about the plugin appears on the right side of the window.

  6. Below the plugin description, click Install plugin.

    Image is a screenshot showing to click Install plugin in the bottom right

  7. In the search results, make sure the box next to it is checked so that it appears.

    Image is a screenshot highlighting the box that needs to be checked to the left of the plugin name

  8. Search for QuickMapServices, and click Install Plugin. Make sure the box next to it is checked, too. For future reference, open GIS Lab has a tutorial and more information about configuring QuickMapServices and accessing more basemap options than the default.

    Image is a screenshot of the QuickMapServices plugin information window

  9. When both plugins are installed, close the plugins window. Not sure if they are installed? Click the Installed tab in the Plugins window.

  10. From the top menu, click Web. Qgis2Web and QuickMapServices should both appear there. If not, quit QGIS and reopen the project. If it still does not appear, go back to the manage and install plugins window and check that these are listed in Installed Plugins. If the plugins are listed there, make sure the box to the left of the plugin is checked.

    Image is a screenshot of highlighting that the two plugins are available under Web

Adding tabular data to QGIS

  1. From the top menu, click Layer>Add Layer>Add Delimted Text data.

    Image is a screenshot that shows Layer and add layer menus of QGIS with add delimited text data highlight

  2. Click the three dots to the far right of File Name to navigate to the CSV used in this workshop.

  3. Under Geometry Definitions make sure Point coordinates is selected.

  4. Still in the Geometry Definition box, click the globe button to the far right of Geometry CRS.

    Image is a screenshot that shows an arrow pointing to the globe button

  5. In the Filter search bar type EPSG:4326. The coordinate system, or CRS, used needs to correspond with the coordinates in the CSV. The coordinates are in the geographic coordinate system WGS 1984 format.

  6. Once found, highlight it, and click OK.

  7. All other system defaults or detected attributes should be OK, so click Add. Then, click Close as there are no other files to add from a delimited text source.

  8. The points should appear in the main workspace, and the CSV should appear in the Layers panel.

    Image is a screenshot that shows an arrow pointing from the layers panel with the wf layer to the points in the workspace

Create Projected GeoJSON

Now, the data in the CSV needs to be reprojected to match the OpenStreetMap projection–a projected coordinate system.

  1. Open the Processing Toolbox panel. Do this by clicking the gear icon, or from the top menu, View>Panels>Processing Toolbox.

  2. Search for reproject, and double click Reproject layer under Vector general.

    Image is a screenshot highglighting the Reproject layer tool in the processing toolbox

  3. For the parameters in the window that appears:
    • Input layer should be the CSV. Search for it if necessary.
    • The Target CRS is EPSG:3857. If it is not in the dropdown, click the globe icon and search for 3857. This projection appears under Projected Coordinate Systems>Mercator>WGS 84 / Pseudo-Mercator, Authority ID EPSG:3857.
    • For Reprojected, click the three dots, and choose Save to File. Navigate to where you want the file saved. This should be somewhere in the git repository.
    • In the Navigator window, change the output file type to .geojson, give it a name, and choose the Git repository for this project as the file directory path to save the output.

    Image is a screenshot showing how the parameters are input

  4. When the screen looks like the above image, click Run in the bottom right of the Reproject Layer window.

  5. Close the Reproject Layer window when the Log tab shows the layer was reprojected successfully by displaying the message “Algorithm ‘Reproject Layer’ finished”

  6. Remove all layers from the Layers panel by right clicking the layer and choosing Remove Layer, highlighting layers and clicking the Remove icon in the Layers panel, OR pressing command + D on the keyboard.

Image is a screenshot showing the remove layer icon in the layers panel

  1. Add the reprojected layer by dragging it into the Layers panel. The layer should be in the git repository–if it is not, move it there before placing in the layers panel. This is the only item that should appear in the Layers panel! Additionally, make sure you can see the points in the QGIS workspace area.

Image is a screenshot showing the points appearing in the workspace

  1. In the Layers Panel double click the wf geojson layer to open the Layer Properties window. Click the Information tab to make sure next to CRS is EPSG:3857. If it is close the window.

  2. Double check the project CRS by looking in the bottom right of QGIS. It should show EPSG:3857. If it does not click whatever EPSG code is there, and search for 3857 in the pop up, select it, and click OK.

Image is a screenshot showing the current project projection of EPSG 3857

  1. From the top-level toolbar, click Web > QuickMapServices > OpenStreetMap > OSMStandard.

Image is a screenshot showing the location of the basemap options

  1. Do the places look correct on top of the OpenStreetMap basemap?

Image is a screenshot showing the places on top of the OSM basemap

Edit the data

Now that a spatial data file (GeoJSON) was created, there is no need for the latitude and longitude field. It is optional to either keep or delete these for aesthetic purposes.

  1. Make sure QGIS is open and the reprojected geojson is in the Layers Panel.

  2. Right click the layer in the Layers panel, and choose open attribute table.

    Image is a screenshot showing the location to open the attribute table

  3. To edit the attribute table, click the pencil icon in the top left of the attribute table or use Command + E (Mac).

    Image is a screenshot showing the location to start editing

  4. To start deleting empty columns, click the Delete field icon, highlighted in the image below. This icon appears when editing mode is turned on. Note: Deleting a column is permanent. You may want to copy the geojson if this is your first time just in case.

Image is a screenshot showing the location to delete attributes option

  1. In the window that appears, click the following columns to select the Latitude and Longitude columns in order to delete them.

    Image is a screenshot showing the columns to delete

  2. Once all the necessary columns are highlighted, click OK.

  3. If the correct columns were deleted, click the floppy disc icon in the top left to save edits, or press Ctrl + S on the keyboard.

    Image is a screenshot showing the columns to delete

  4. While in the attribute table, make any other content edits.

  5. Click the pencil icon in the top left again when finished. Make sure to save edits.

Styling the map

You may wish to style the points or categorize the data on the map. This tutorial will not go in depth to discuss layer styling. If you have never styled or categorized vector data in QGIS before or need a refresher, QGIS Tutorials has a good Vector Styling tutorial.

Alternatively, you can also leave the default point marker and change it to a leaflet style, which is demonstrated in a later step.

  1. Double click the points layer with the World’s Fair locations, shown here as wf.

  2. In the Layer Properties window that appears, click the Symbology tab.

  3. From the dropdown at the top of the screen choose Categorized.

  4. Click the Column dropdown to choose a categorical feature to style the points. In this dataset, choose Type.

  5. Near the bottom of the window, click Classify.

  6. Highlight the line with the point that appears without any values.

  7. At the bottom, click the minus sign.

  8. Double click the points under Symbol to style them. Choose new colors or symbols.

  9. Close the Layer Properties window when happy with the styles.

Using qgis2web to export Leaflet code

The point of using qgis2web instead of immediately starting with Leaflet is that qgis2web can output complex and correct javascript for pop-ups, legends, and other map options without needing to know the code. Then, it is very simple to go into qgis2web’s file outputs to make customizations and additions for basemaps, markers, more places, etc.

  1. From the top toolbar in QGIS, click Web>qgis2web>Create web map.

Image is a screenshot showing the create web map menu

  1. In the bottom left of the window that appears, click the radio button for Leaflet, and if needed, click Update preview.

Image is a screenshot showing the Leaflet option and Update preview button

  1. Make sure the map appears in the right side of the Export to web map window. If nothing appears or only one layer appears, there are two simple possibilities: 1) Leaflet is not selected or 2) the projection is probably incorrect–return to the Create Projected GeoJSON section.

Image is a screenshot showing the map preview

  1. Under Layers and Groups, change the Popup fields dropdowns. I prefer to use header label, but the other options are inline label and None. None means the field will appear but without a label.

Image is a screenshot showing the popup fields as header labels

  1. Click the Appearance tab, from the Add layers list dropdown choose one of the options. Choosing collapsed or expanded will add a legend to the map.

Image is a screenshot highlighting the Add layers list option

  1. Make any other desired appearance changes. For example, and a layer search and/or address search to make the map more web accessible, measure tool, or have a custom map extent (how far someone can zoom in, out, and around). Click Update preview to see how any changes will look.

  2. Click the Export tab.

  3. Under Data export and to the right of Exporter, click the three dots at the end of the line to make sure the output goes to the git repository folder.

Image is a screenshot highlighting the three dots to choose where the export goes

  1. In the window that appears, navigate to the project’s git repository and choose Open.

  2. In the Export to web map window in QGIS, click Export at the bottom of the window.

Image is a screenshot highlighting where the Export button is

  1. When the map successfully exported, click OK. The log will show Success and the export file path if it is successful.

    Editing qgis2web index.html file

  2. Navigate to the qgis2web folder in the git repository.

  3. Rename the very long qgis2web folder name to webapp. This rename will be important for creating GitHub Pages at a later step. It is not necessary to use webapp specifically, but name it something short and memorable.

  4. Open the folder, which is now named webapp in this tutorial, and double click the index.html file. The map will open in the default web browser. If for some reason the map is not appearing, right click the file and select Open with to open it with another web browser (e.g., Firefox instead of Chrome).

  5. Keeping the map in the browser open, now, right click the index.html file and choose Open with… and select Atom.app.

Image is a screenshot demonstrating how to open the file with Atom

  1. Within the head tags (<head>), delete line 6, or the line which begins meta name="viewport"....

Image is a screenshot demonstrating how to open the file with Atom

  1. Copy and paste all of the following lines of code in its place or anywhere in the head <head> above the style tag <style>. Leaflet is meant to create mobile and web responsive maps, but these will help even more.
<!-- Mobile meta tags to go in head-->
<meta name="HandheldFriendly" content="True">
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
<meta name="MobileOptimized" content="320"/>
<meta name="apple-mobile-web-app-capable" content="yes">
<meta http-equiv="cleartype" content="on">

Image is a screenshot showing the extra mobile tags pasted into hte head

  1. In the style (<style>) section of the head, paste the following code in line 25, or after the closed curly bracket. Note: the line could be different if you did not paste the code from the previous step exactly as shown, so just look for the line directly above the closed style tag </style>. This code sets a minimum width and height for the map popups and adds scrolling capabilities. Change the min-width and min-height to meet your needs.
.leaflet-popup-content {
min-width: 200px;
min-height: 100px;
overflow-y: scroll;
}

Image is a screenshot showing where to paste the customized popup code in line 23 after the closed curly bracket

  1. (Optional) Use command + F to find marker.

Image is a screenshot showing where to find the point markers

  1. (Optional) Change L.circleMarker to L.marker to use the default Leaflet balloon markers instead of the one exported from QGIS. No need to delete any of the function style_wf_1_0, Leaflet will now ignore it.

  2. (Optional steps 10-14) Change the basemap to the Google Earth and Streets hybrid basemap. Note: It is possible to use Google Earth, Streets, or Hybrid from the start if QuickMapServices is configured with the open GIS Lab tutorial.

  3. Use command + F to find var layer_OSMStandard_0. This text may vary if you used a different basemap from the start.

  4. Delete the lines of code that are as follows:

var layer_OSMStandard_0 = L.tileLayer('http://tile.openstreetmap.org/{z}/{x}/{y}.png', {
            opacity: 1.0,
            attribution: '<a href="https://www.openstreetmap.org/copyright">© OpenStreetMap contributors, CC-BY-SA</a>',
        });
        layer_OSMStandard_0;
  1. Replace the code with the following:
var googleHybrid = L.tileLayer('https://{s}.google.com/vt/lyrs=s,h&x={x}&y={y}&z={z}',{
    maxZoom: 20,
    opacity: 1.0,
    subdomains:['mt0','mt1','mt2','mt3']
  });

googleHybrid;
  1. Do a find and replace (command + F) for anything else that remains as layer_OSMStandard_0 and replace it with googleHybrid

Image is a screenshot showing the Atom find and replace window.

  1. Make your map secure. NOT OPTIONAL: Open find and replace (command + F) to find all instances of http: web addresses and replace it with https:. Only do this with web addresses and NOT any http instances within a variable name or tag). This is necessary so that the final map does not create an insecure connection on websites. If this is not done, the website the map is embedded will appear as insecure.

Image is a screenshot showing http web address

Image is a screenshot showing the change to an https web address

  1. (Optional) Edit the legend to reflect the changes made such as the new basemap name and to remove the old marker image.

  2. Use command + F to find the line that begins with L.control.layers.

Image is a screenshot showing the Atom find and replace window.

  1. Some further changes that can be made:
    • If the places marker was changed, delete the image path that displays the old icon. You can add a new marker image by going into the webapp folder directory and adding it to the image folder.
    • Capitalize or change the name of the layer.
    • If the Google Hybrid basemap was used, replace the OSM Standard name in quotations with something like Google basemap

Image is a screenshot showing the image path to delete.

Image is a screenshot showing the image path to delete.

  1. Make sure to continue to refresh the map in the browser to check the updates. Do the changes appear? If the map is not appearing at all, try to troubleshoot the code in the index.html file:
    • Was a colon or curly bracket accidentally deleted?
    • Were all variable names changed if choosing a new basemap?

      Push changes to GitHub

  2. Open GitHub Desktop.

  3. From the top left, make sure the current repository is the one with all of the data and Leaflet files.

Image is a screenshot showing where to find the Current Repository.

  1. At the bottom, provide at least a summary for the changes and a description if desired, and click Commit to master.

Image is a screenshot showing a summary and description.

  1. In the top right, click Push origin.

Image is a screenshot showing the Push origin button in Github Desktop.

Integrating with a website

The simplest way to embed the Leaflet map into a website is with an iframe. This may or may not be possible depending on the content management system being used. If you do not have a website, try creating a Jekyll blog that integrates with Github Pages. Note: This has not been tested by the tutorial author, but there is a good Jekyll tutorial.

As of May 2019, iframe html tags <iframe> do not seem to be compatible with the most recent version of free, personal instances of WordPress. The best reason I could find was “due to security reasons.”

Iframe html tags (e.g., <iframe src=" ">) may work with other content management systems and some older versions and instances of WordPress.

If you want to integrate the exported qgis2web map with a content management system that does not allow the iframe html tags or you do not currently have access to one there are a few ways to do it:

  1. A WordPress business plan to access the iframe plugin.
  2. A hosting service that allows you to upload html pages in the content management system’s source code, but this may still require some use of an iframe. This has not been tested successfully by the tutorial author, but it is known to be possible.
  3. Create a link on a website you do have admin access to and link out to the gh-pages from the website. Work with the index.html file from qgis2web to start adding your own text and html to create a functional page or at least linking back to the original website. For example, the WIDH visitor map.

Using the iframe html tag

This option may work with some content management systems, self-hosted websites, or older versions of WordPress.

  1. Create a new page or post in the content management system. This example uses WordPress.

  2. Using the classic editor, choose Text instead of Visual.

  3. Use the html iframe tag: <iframe src=" " width=" " height=" "></iframe>

  4. Between the iframe src= quotation marks, paste the link to the GitHub Pages (gh-pages branch) for the project repository. It should look like https://YourGitHubAccount.github.io/repoName/webapp.

  5. Between the width and height quotations, set the width and height of the map. For example, the final html might look like: <iframe src="https://taylorhixson.github.io/WF/webapp" width="100%" height="400"></iframe>. For width=, the 100% indicates stretching to fill the page width. It is also possible to set the width to a static number such as width="800".

  6. Click Preview to check out how it appears.

Map text description

Maps are great! However, they may not be accessible to all users for reasons ranging from low-internet connectivity, incompatibility with a screenreader and/or keyboard-only navigation, vision impairment, and neurological differences.

Wherever the map is hosted, include a thorough text description. It is even possible to do add a text description within the index.html with basic html knowledge! Drafting the text descriptions in a spreadsheet from the start helps with the text description process because it makes it easy to directly copy text into the post editor. If the places were not listed in any particular order, make an effort to arrange the text descriptions in a way that will make narrative sense.

For example, if the map is of places, make an effort to provide a narrative or list that describes the places in the order they were visited. A thorough text description aims to give an equivalent experience to all users.

Bonus materials on image processing

Reformat images

The images I downloaded from the database for this workshop came in PDF format. For web viewing a thumbnail within the map popups, I thought a .png file was more appropriate. To reformat images use the following commands. These instructions are for Mac. The commands may or may not be compatible with other operating systems.

  1. Copy photos into a new folder in the git repository for this project. Make sure to COPY the images or have a backup of the original in case any errors occur.

  2. Skip to step 4 if you already know how to open and navigate within Terminal. Open Terminal. If you are not sure where Terminal is, type Terminal into Mac’s spotlight.

Image is a screenshot of searching for Terminal in Mac's spotlight

  1. Navigate to the git repository folder with the images using the command cd (change directory). For example, use a relative file path like:
  cd ~/git/WF/images
  cd git
  cd WF
  cd images
  1. Once in the directory, to batch reformat all the files into PNGs use the following command in Terminal: for i in *; do sips -s format png $i --out $i.png; done

The above will reformat all files in the directory, so if you have varied types in the folder such as PDFs and TIFFs that you want to turn into PNGs, this should still work.

Alternatively, reformat a single image using the following: sips -s format png 1873.pdf --out 1873.png

Note: replace the input and output file names and file types with your own.

Resize images

These instructions are for Mac. The commands may or may not be compatible with other operating systems.

  1. Copy photos into a new git repository folder titled images_small. Make sure to COPY the images or have a backup because these images will be resized.

  2. (Optional) Rename the photos to something simpler or more systematic to make it easier to link them with the corresponding places in a later step.

  3. Skip to step 4 if you already know how to open and navigate within Terminal. Open Terminal. If you are not sure where Terminal is, type Terminal into Mac’s spotlight.

Image is a screenshot of searching for Terminal in Mac's spotlight

  1. Change the directory using the command cd (change directory) to the git repository with the images. For example, use a relative file path like:
  cd git/WF/images
  cd git
  cd WF
  cd images
  1. Once Terminal shows that it is in the correct directory for the images for this project, use the following code to resize all images to 300 pixels, or the desired size:
  sips -Z 300 *.jpg

Format a column in html so that the photo will show up in the map popup. If you resized the image and want to link back to the original or larger format, create to columns: one with the image link to the large format one, and one with the html formatted image link to the resized image as shown how to format below.

  1. Go to GitHub.com, and go to the project repository.

  2. Click the images folder. This assumes there is a folder called images in the repository where images are saved.

  3. Click on an individual image link in the folder.

  4. Right click the image, and choose Copy Image Address.

Image is screenshot highlighting the Copy Image Address selection when an image is right-clicked in a GitHub online repository

  1. Open the spreadsheet with the place names and descriptions from the List places… section.

  2. Paste the image link into an empty column in the appropriate row where the image depicts the place listed and described. If using a new spreadsheet, place it A1.

Image is a screenshot of an image address pasted into the A1 cell of Google Sheets

  1. Keep copying and pasting image addresses next to any place with a corresponding image for all remaining images.
    • Note: There are many ways to get the image links into the spreadsheet. For example, you can also copy and paste a single image link down the spreadsheet and change just the image name in the link. If there are more than 20 images, finding an automated way to capture addresses may be helpful.
  2. In an empty cell in the rows with images, create alt text to be read by screen readers or to display when the image does not appear. Alt text should be descriptive of the image not the experience.

Image is screenshot showing an image link in column a column titled Thumbnail and alternative text in column a column titled AltText

  1. In the first empty cell in the next empty column type =CONCATENATE to activate the Concatenate formula.

  2. Within the Concatenate formula parentheses () type: "<img src=+",A1,"+ alt=+",B1,"+>". In the formula the plus sign (+) acts as a placeholder for quotation marks needed in the html. Quotations may or may not work with the Concatenate formula in your spreadsheet software, but it definitely does not work in Google Sheets. Additionally, your columns (e.g., A1, B1) may be different depending on where links and alt text are placed.

  3. Copy this formula down the column or into any cell that has an image and alt text.

  4. Copy the column and paste as values in the next empty column. In Google Sheets, use command + shift + v to paste as values, or right click/control click the first empty cell and choose Paste Special>Paste Values Only.

  5. Use find and replace to replace the +, or special character used, as a placeholder with a quotation mark.

    • Highlight the column where the formula was pasted as values only. This will make sure only this range is searched for find and replace.
    • Press command or ctrl + F to open find and replace in Google Sheets.
    • In Google Sheets, press the three stacked dots at the right of the window for more options.
    • Type + in Find and in Replace with. Select replace all. Then, press Done.

Image is a screenshot of using Find and Replace to find plus signs and replace them with quotation marks

Image is a screenshot highlighting how the find and replace works in the spreadsheet to replace all plus signs with quotation marks

  1. Delete the column with the Concatenate formula, NOT the column with the final image link.

  2. Now, there are a few options for how to integrate the image links:

    • Concatenate the Description column and the column with the final image links. If doing this, add a html manual line break <br> in the concatenate formula. This will NOT show the line break immediately, but the break should appear in the final map.
    • In the column with the final image links, add the column title Image.
