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.

• Built on top of FastAPI
• Cloud Optimized GeoTIFF support
• SpatioTemporal Asset Catalog support
• Multiple projections support (see TileMatrixSets) via morecantile.
• MultiDimensional dataset support via Xarray
• 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)

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.xarray		The xarray package contains libraries to help create a dynamic tiler for Zarr/NetCDF datasets
titiler.extensions		TiTiler's extensions package. Contains extensions for Tiler Factories.
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

To install from PyPI and run:

# Make sure you have pip up to date
python -m pip install -U pip

python -m pip  install titiler.{package}
# e.g.,
# python -m pip  install titiler.core
# python -m pip  install titiler.xarray
# python -m pip  install titiler.extensions
# python -m pip  install titiler.mosaic
# python -m pip  install titiler.application (also installs core, extensions and mosaic)

# Install uvicorn to run the FastAPI application locally
python -m pip install uvicorn

# Launch application locally
uvicorn titiler.application.main:app

To install from sources and run for development:

git clone https://github.com/developmentseed/titiler.git
cd titiler

python -m pip install -U pip
python -m pip install -e src/titiler/core -e src/titiler/xarray -e src/titiler/extensions -e src/titiler/mosaic -e src/titiler/application
python -m pip install uvicorn

uvicorn titiler.application.main:app --reload

Ready to use/deploy images can be found on Github registry.

• https://github.com/developmentseed/titiler/pkgs/container/titiler
