Maps and Layers

All Fulcrum accounts come with a list of online basemaps provided by Google, but you can always create and upload your own offline .mbtiles file that can be used either as a basemap or a layer. Load MBTile files to create interactive overlays of point, line or polygon data to help guide your data collection project in the field.

When working on a WiFi or 3G or greater network you can choose from the list of Online Maps or choose to download your offline map(s) that will be cached to the app. Be sure to download your offline maps over WiFi before heading out to collect data in offline environments since downloading these large files on your cellular plan uses your network data.

With Fulcrum, you can use your own custom maps as layers and/or basemaps. Fulcrum supports the MBTiles file format. Check out our adding layers and creating your own maps pages for more information.

Both Basemaps and Layers can be managed directly from the app settings menu.


Add layers or custom basemaps for offline use through the web or directly to your Android device. The layers settings allows you to download, enable, or disable a layer. Clicking the file icon in the top right will allow you to locate a layer that was directly loaded to the device.

You can arrange your layers by pressing and dragging them in the order you wish to have them loaded. The layers at the top will be presented on the highest level.

To delete a layer locally, tap on the trashcan icon in the upper right corner and select which layers you would like to delete.


In the basemaps section, you will find a list of maps that can be used while you are connected to a WiFi network or have a cellular data connection.
