No files? No problem! You can upload any of the Upload Anything directly as a URL to Felt by clicking the icon in the section of the toolbar or by directly pasting the URL onto your map (Cmd+V / Crtl+V).
Felt supports uploading data from publicly accessible URLs such as:
Google MyMaps
Google Sheets
XYZ Raster Tiles
Esri: FeatureServer, MapServer and ImageServer
OGC Web Services: WMS, WMTS and FeatureServer
Flat files: all of the file formats in this page, hosted at a URL
For example, simply paste the following URL to add country data from Natural Earth to your Felt map:
Paste in a valid TileJSON endpoint and click Next. Felt will automatically read the Min zoom level, Max zoom level, Bounds and Layer IDs from the source
Next, select which tileset Layer IDs to add and the Geometry type for each and click Add to map
When adding a TileJSON source, you'll need to manually specify whether your data contains points, lines, or polygons. This step is necessary for proper rendering and styling of your vector tile layers.
If it is a categorical visualization
Use the Color by dropdown and choose the attribute you want to style by
For the Showing dropdown click Add categories...
In the Set Categories panel, click Add all to pull in the attribute values in your current view
If it is a numeric visualization
Use the Color by or Size by dropdown to choose the attribute you want to style by
Click Set steps... next to the Steps dropdown
Click Set as range to use values from the current view or manually enter a custom min and max Range
Attribute values are loaded from the data currently visible in your map view. Zoom or pan to see more, then click Add all again to expand the category list or Set as range to update the min/max.
Because the data are streaming directly from a remote server, some classification methods, the data table, Components and Filters are unavailable.
Import all the layers in your MyMaps directly into a Felt map by just copying and pasting the MyMaps link!
Tips:
Make sure that your MyMaps share permissions have been updated so Anyone with this link can view is turned ON
Copy and paste the link directly in onto the map in Felt and click the Add to map option in the pop-up
Links to Google Sheets will behave just like regular spreadsheets and CSV files provided they are public. This means they must be viewable by anyone with the link.
Felt supports OGC URLs that point to public services from the following Open Geospatial Consortium standards:
Web Map Services (WMS) and Web Map Tile Services (WMTS): added as raster layers.
Web Feature Services, added as vector layers.
Here’s an example raster URL of the city of Aberdeen from the National Library of Scotland:
Felt displays tiles in the WebMercator projection (code EPSG:3857). For tiles from a WMS or WMTS server to be displayed in Felt, they must be served from a compatible TileMatrixSet, usually called GoogleMapsCompatible.
Users do not need to specify which TileMatrixSet needs to be used. However, if Felt does not find any compatible ones in the server, an error will be returned.
Felt will automatically try to parse and upload all layers from the service. However, Felt has a maximum of 50 layers per upload. If the service hosts more than that amount, an error will be returned.
For OGC services, users can work around this by specifying which layers to request in the URL query parameters:
WMTS and WFS: a single layer in the form of ?layer=X
WMS: one or more layers in the form of ?layers=X,Y
Ever found yourself on a page without knowing what to do? Many public data sources are only available as Esri MapServers or FeatureServers, which are hard to work with. Fortunately, you can simply upload the URL into Felt and let us do the work. Felt supports two kinds of Esri server URLs:
URLs ending in a number (like /MapServer/0) point to a single layer in the server and will result in a single-dataset layer inside Felt.
URLs ending in /MapServer (or /FeatureServer or /ImageServer) point to the whole server, which may contain many layers. Uploading one of these to Felt will result in a multi-dataset layer.
To add services that require an API token, you can access as an cloud source.
You can add external vector tile sources directly into your maps using TileJSON URLs to stream data from external hosts and visualize large, global, or frequently updating datasets. You can also set to keep your map current with the latest data.
This feature is only available to customers on the . To upgrade, .

Tiled raster services in XYZ (slippy maps) can also be imported as URLs. However, they must be imported as template URLs, which means the URL must contain the following parts: {z} (zoom), {x} (row) and {y} (column). Instead of the {y} parameter, {-y} may also be used to indicate that tiles are served in format. They must also end in .png, .jpg or .jpeg.
