About geodata

pub package

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.

Client-side support for the OGC API Features standard:

Standard partSupport in this package
OGC API - Features - Part 1: CoreSupported for accessing metadata and GeoJSON feature collections.
OGC API - Features - Part 2: Coordinate Reference Systems by ReferenceSupported.

External packages geodata is depending on:

  • equatable for equality and hash utils
  • geobase for base geospatial data structures
  • http for a http client
  • meta for annotations
