Technical Overview

  • Core abstract API; web framework agnostic (default Flask)
  • YAML configuration (metadata, dataset connections)
  • Automated OpenAPI document generation and data binding
  • Robust plugin framework (data connections, formats, processing)
  • Easy deployment (pip install, Docker, conda, UbuntuGIS)
  • Minimal core dependencies

Provider plugin framework

  • Features (Elasticsearch, PostgreSQL/PostGIS, CSV, GeoJSON, OGR, MongoDB, Esri, Azure)
  • Coverages (xarray, rasterio)
  • Tiles (MinIO, ZXY directory tree)
  • Records (Elasticsearch, TinyDB)
  • WxS facades / bridges (WMS/WMTS, WFS, CSW)
  • Implement your own!

Processing framework

  • Expose your Python workflow as processes
  • Process manager support for job control
  • Implement your own!

Implementing your own Plugin

  • Develop / propose / maintain as core plugin
  • Develop / maintain in your own repository

Community Plugins and Themes

github.com/geopython/pygeoapi/wiki/CommunityPluginsThemes -- add yours!

schema.org

  • Lower the barrier to data search
  • HTML encoding is annotated as schema.org/Dataset to facilitate search engines
  • Google dataset search locates pygeoapi datasets

Linked Data - JSON-LD

  • JSON-LD provided as additional representation
  • Default out of the box functionality for most pygeoapi resources / endpoints
  • Additional configuration

Deploying

Numerous deployment options

  • PyPI
  • UbuntuGIS
  • Docker
  • Conda
  • FreeBSD
