Titiler Ecosystem Overview

The TiTiler ecosystem is a comprehensive suite of Python tools for creating dynamic tile servers from geospatial datasets. The components are organized by their primary function and built upon a layered architecture that provides flexibility and specialization for different use cases.

Architecture and Relationships

The TiTiler ecosystem follows a layered architecture that promotes code reuse and specialization:

Foundation Layer

Extension Layer

Application Layer

  • titiler.application: Reference implementation using titiler.core
  • titiler-multidim: Prototype application using titiler.xarray + optimizations
  • titiler-cmr: NASA-specific application using titiler.core + CMR integration
  • titiler-eopf: ESA-specific application using titiler.xarray + EOPF integration

Key Relationships

titiler.core → titiler.xarray

titiler.xarray extends the core framework with xarray-based readers and multidimensional dataset support, inheriting all core functionality while adding temporal and dimensional processing capabilities.

titiler.xarray → titiler-multidim / titiler-eopf applications

Both titiler-multidim and titiler.eopf are built on titiler.xarray, leveraging its multidimensional capabilities while adding their own optimizations:

  • titiler-multidim adds Redis caching, VEDA platform integration, and prototypes of optimizations
  • titiler-eopf adds EOPF-specific data structures, collection/item routing, and ESA workflow integrations

titiler.core → titiler-cmr application

titiler-cmr is built directly on titiler.core rather than titiler.xarray due to the development timeline of the two projects. In the future, we anticipate titiler-cmr will depend on titiler.xarray, with progress tracked by titiler-cmr issue #35.

The TiTiler ecosystem provides a complete stack for building scalable, cloud-native tile servers that can handle everything from simple COG serving to complex multi-dimensional scientific datasets.
