Map sharing with Fulcrum and

One of the central principles with Fulcrum is to always allow users access to their data in as many flexible and open-standard formats as possible, and not to lock users up in a specific data format. So we make quite a few formats available for exporting data from your Fulcrum projects, including GeoJSON. This means you can take any export files from Fulcrum, drag and drop them into the window in the browser, and instantly visualize or share that data.

But this gets cooler using Fulcrum’s data share feature, which allow you to create shareable URLs to your live data in several formats, including GeoJSON, KML, and CSV format. Anytime you browse to the data share URL (or hit that URL from a web service), Fulcrum will return all of the current data right from your account. has a neat way to read your data share URLs built right in. Using a special URL parameter, you can paste in your own GeoJSON data share URL, and get a shareable map instantly in From here you can make additional annotations, or save the map for later viewing and sharing. You can also generate quick map embeds to stick on your own website or blog post. Here’s what you do:

  • Copy your data share URL as GeoJSON from your Fulcrum account
  • Append it to the URL in like so (where the Fulcrum URL is copied from your account):,
  • Paste that URL into your browser and watch it load your Fulcrum data

Now with your current live data loaded into the map, you can add further annotations, set the bounds and center point, and share with others. is also open source and hosted on GitHub.
