Project description
A lightweight dynamic tile server.
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 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)
Installation
$ pip install -U pip
# For rio-color, we need to install numpy before installing titiler
$ pip install numpy
# From Pypi
$ pip install titiler["server"]
# Or from sources
$ git clone https://github.com/developmentseed/titiler.git
$ cd titiler && pip install -e .["server"]
Launch Application
$ uvicorn titiler.main:app --reload
Or with Docker
$ git clone https://github.com/developmentseed/titiler.git
$ cd titiler
$ export AWS_ACCESS_KEY_ID=...
$ export AWS_SECRET_ACCESS_KEY=...
$ docker-compose build
$ docker-compose up
