A modern dynamic tile server built on top of FastAPI and Rasterio/GDAL.

Documentation: https://devseed.com/titiler/

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 set of python modules that focus on creating FastAPI application for dynamic tiling.

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

Features

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

Packages

Starting with version 0.3.0, the TiTiler python module has been split into a set of python namespace packages: titiler.{package}.

Package	Version	Description
titiler.core		The Core package contains libraries to help create a dynamic tiler for COG and STAC
titiler.mosaic		The mosaic package contains libraries to help create a dynamic tiler for MosaicJSON (adds cogeo-mosaic requirement)
titiler.application		TiTiler's demo package. Contains a FastAPI application with full support of COG, STAC and MosaicJSON
