About geodata
Key features of the geodata package:
- 🪄 Client-side data source abstraction for geospatial feature service Web APIs.
- 🌐 The GeoJSON client to read features from static web resources and local files, supports also Newline-delimited GeoJSON data.
- 🌎 The OGC API Features client to access metadata and feature items from a compliant geospatial Web API providing GeoJSON data.

| OGC API - Features - Part 1: Core | Supported for accessing metadata and GeoJSON feature collections. |
| OGC API - Features - Part 2: Coordinate Reference Systems by Reference | Supported. |
