## What it is
TiTiler is a set of Python packages for building dynamic raster map tile services on top of FastAPI and Rasterio/GDAL. It serves tiles from Cloud Optimized GeoTIFFs, STAC items, Zarr datasets, and MosaicJSON virtual mosaics with support for multiple projections and OGC tile APIs.

## Use cases
- serve map tiles from cloud optimized geotiffs
- build a dynamic raster tile server for web maps
- create tile endpoints for STAC satellite imagery
- serve virtual mosaics from mosaic
- deploy a serverless tile API on AWS Lambda
- render zarr or netcdf multidimensional datasets as tiles
- support multiple tile matrix sets and projections in a tile service

## When to choose
- you need on-the-fly map tiles from COGs, STAC, or Zarr without pre-generating tiles
- you want a customizable FastAPI-based tiling service deployable to Lambda, ECS, or Kubernetes
- you need OGC Tiles/WMTS API compliance and multiple projections

## When to avoid
- you only need to serve pre-rendered static tiles from a file server
- your data is vector rather than raster
- you want a turnkey GIS server with full WMS/WFS support rather than a tiling framework
