Source Code: https://github.com/developmentseed/titiler

Titiler, pronounced tee-tiler (ti is the diminutive version of the french petit which means small), is a lightweight application (FastAPI) focused on creating web map tiles dynamically from Cloud Optimized GeoTIFF, STAC or MosaicJSON.

Note: This project is the descendant of cogeo-tiler and cogeo-mosaic-tiler.

Features

Cloud Optimized GeoTIFF support
SpatioTemporal Asset Catalog support
Virtual mosaic support (via MosaicJSON)
Multiple projections (see TileMatrixSets) via morecantile.
JPEG / JP2 / PNG / WEBP / GTIFF / NumpyTile output format support
OGC WMTS support
Automatic OpenAPI documentation (FastAPI builtin)
Example of AWS Lambda / ECS deployment (via CDK)
