This package enables dynamically-generated geospatial products to be shared. It partially implements the Open Geospatial Consortium (OGC) WCS/WMS specifications.

Organization

The list below lists some relevant classes. It is not exhaustive.

• ogc/core.py: defines interface and to some extent implements:
  • ogc.OGC class: necessary functions to support an ogc server, but not specific to any WSGI/ASGI server (e.g. Flask). Return values are native python objects (strings for xml, io.BytesIO for binary) when possible rather than something specific to a web framework like Flask
• ogc/__init__.py
  • ogc.GridCoordinates class: Used to represent footprint of WMS/WCS coverages/layers in relevant CRS.
  • ogc.Layer class: Necesary properties/functions for a single WMS/WCS coverage/layer offering
  • ogc.Style class: Used for styling or coloring WMS layers and storing metadata
• ogc/podpac.py: PODPAC implementations of:
  • podpac.OGC class:
  • podpac.GridCoordinates class:
  • podpac.Layer class:
• ogc/servers.py: implementations of OGC server in specific WSGI/ASGI web frameworks (e.g. Flask, FastAPI). These will all wrap ogc.OGC class.
• ogc/app.py: An example server app.

Installation
