morecantile
Construct and use map tile grids (a.k.a TileMatrixSet / TMS).
Decision gist · record as of 2026-08-14
Yes. Morecantile is actively maintained, has no known vulnerabilities, low install friction, and permissive licensing. Install it if you need to work with map tiles in coordinate systems other than Web Mercator, or if you're building OGC-compliant geospatial services. The library is well-established in the geospatial Python ecosystem.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11 or later; pyproj dependency may require system PROJ libraries on some platforms.
- Low friction: pure Python wheel with four runtime dependencies (attrs, click, pydantic, pyproj).
- Actively maintained with recent releases; last commit 2026-08-09.

What it is and what it does
Morecantile is a library for constructing and querying map tile grids (TileMatrixSets) that conform to the OGC Two Dimensional Tile Matrix Set specification version 2.0. It extends the concept of Web Mercator tile indexing to support arbitrary coordinate reference systems and tile grid definitions. The library provides a set of built-in grids covering common projections (Web Mercator, UTM, polar stereographic, and regional systems) and allows you to define custom grids.
You use it to convert between tile coordinates and geographic or projected bounds, retrieve bounding boxes for tiles in their native CRS or in geographic coordinates, and manage tile grid metadata. It's commonly used as a foundation for tile-based geospatial services, raster tile generation, and OGC-compliant tile APIs.
Use it for
- Generate tile coordinates and bounds for raster data served in non-Web Mercator projections like UTM or polar stereographic.
- Build OGC-compliant tile servers that support multiple TileMatrixSet definitions.
- Convert between tile indices and geographic/projected coordinates for geospatial analysis.
- Integrate tile grid logic into map rendering or tile caching systems.
- Support regional mapping applications using country-specific or continent-specific tile grids.
