# titiler-application — A modern dynamic tile server built on top of FastAPI and Rasterio/GDAL.

License: permissive · Maintenance: active · Downloads: 81.9K/mo

## 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 above — 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

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.
