Project description
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.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 |
Installation
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.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/extensions -e src/titiler/mosaic -e src/titiler/application
python -m pip install uvicorn
uvicorn titiler.application.main:app --reload

docker run --name titiler \
-p 8000:8000 \
--env PORT=8000 \
--env WORKERS_PER_CORE=1 \
