titiler-application

What it is and what it does

titiler.application is a demonstration FastAPI web service that serves raster geospatial data as map tiles. It builds on titiler-core, titiler-extensions, titiler-mosaic, and titiler-xarray to provide a complete, runnable tile server with support for Cloud Optimized GeoTIFFs, MosaicJSON mosaics, STAC catalogs, and xarray-backed datasets. The application includes a landing page, configurable caching and CORS settings, and exposes OGC-compliant tile endpoints.

The package is intended as both a reference implementation and a starting point for custom tile-serving applications. It demonstrates how to compose titiler's modular components into a working service and can be launched immediately after installation. It targets geospatial professionals, data engineers, and researchers who need to publish raster data as web-accessible tiles.

Use it for:

• Launch a tile server for Cloud Optimized GeoTIFFs without writing custom FastAPI code.
• Serve STAC collections and MosaicJSON mosaics as interactive map tiles.
• Prototype or demo a geospatial tile API before building a production service.
• Integrate xarray-backed climate or scientific data into a web mapping application.
• Explore titiler's capabilities and architecture through a working reference application.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides a ready-to-run FastAPI application for serving Cloud Optimized GeoTIFFs and raster data as dynamic map tiles, with built-in support for STAC, MosaicJSON, and OGC standards.

Yes, if you need a ready-to-run tile server for raster geospatial data. The package is actively maintained, has no known vulnerabilities, and low install friction. It is most valuable as a demo or starting point rather than a production service—for production use, you would typically customize it by extending titiler's modular components. The MIT license poses no restrictions.

Install

titiler-application on PyPI

pip install titiler-application

uv add titiler-application

poetry add titiler-application

Installing titiler-application

Before you install

Low friction: ships as a wheel and depends on six titiler packages that form a cohesive ecosystem. Maintenance is active with a recent release 16 days old and steady repository activity. Requires Python 3.11 or later.

License in practice

MIT license is permissive and imposes no restrictions on use, modification, or redistribution in commercial or private projects.

Quickstart

pip install titiler.application
python -m titiler.application.main

Requires Python 3.11 or later; a web server is needed to run the FastAPI application.

Verify before relying

• Whether the demo application includes example data or requires external raster sources to be configured.
• Performance characteristics and scalability limits for concurrent tile requests.
• Specific GDAL/Rasterio system dependencies and their installation requirements.
