Felt
Interactive GIS mapping platform for projects, maps, layers, elements, and GeoJSON-based feature updates.
Helps spatial workflows that create maps and projects, manage layers and elements through GeoJSON, and share interactive maps with collaborators.

Example Use Cases
These are example ways Snow can use Felt when building apps with you. This list is meant to show examples, not document every possible capability. Connecting an account does not make Snow run these automatically on its own.
Create or update map elements using GeoJSON FeatureCollection format. Creates new elements by default; to update existing elements, include 'felt:id' in the feature's properties. Supports Point, LineString, Polygon, and Multi-type geometries. Returns the created/updated elements with assigned IDs and Felt-specific properties.
Create a new Felt project with the specified name and visibility settings. Projects are organizational containers for grouping related maps within a workspace.
Tool to delete a specific element from a map. Use when you have both map and element IDs and need to remove the element permanently.
Tool to delete a specific layer from a map. Use when you have the map's and layer's IDs and need to remove it permanently.
Permanently deletes a map and all its associated data from Felt. WARNING: This action cannot be undone. The map and all its layers, elements, and comments will be permanently removed. Use when you have the map's ID and need to permanently remove it. Returns no content (HTTP 204) on success.
Tool to delete a project and all its contents. Use when you need to permanently remove a project after confirmation.
Creates a complete copy of a Felt map including all layers, elements, and configuration. Use when you need to clone an existing map to a new location or create a template-based map. The duplicated map can optionally be placed in a specific project or folder.
Retrieves comprehensive details of a specific Felt map including title, URL, layers, elements, basemap settings, access permissions, and timestamps. Requires a valid map ID. Use this when you need to: - Get complete map configuration and metadata - Access map layers and elements - Check map permissions and access settings - Retrieve map URLs for sharing
Tool to retrieve information about the authenticated user. Use after obtaining a valid token to fetch user profile details.
Retrieves all element groups from a Felt map. Element groups are collections of geographic features (points, lines, polygons) organized together. Each group returns a GeoJSON FeatureCollection with the group's elements, along with styling properties like color and symbol. Use this when you need to discover what element groups exist on a map or access grouped geographic data.
