Fulcrum uses a built-in uploader right inside the web app to add your custom layers to your account. Layers that you’ve created in TileMill or another program can be exported to MBTiles format and then uploaded to be used on the both the mobile and web apps.
Add an MBTile Layer in the Web App
On the Side Navigation, click on 'Setup' to display the available options. There under the 'APP SETUP' section, click 'Map Layers'. To add a layer, select layers from the navigation pane/sidebar on the left side of the Fulcrum web app.
Once you are redirected to the Map Layers page, click the + New Map Layer button, located on the top right corner of the screen.
This brings up the New Layer form. Here all you have to do is fill out the form with the requested information, following these steps:
Select 'MBTiles' as the layer type.
Give the layer a name. Optionally, you can add a description for your layer.
Select the MBTiles file you would like to use, or drag and drop it to the file box.
Set the member permissions if you need to make some changes.
Once you are done setting up the new layer, click the 'Create Layer' button.
