BETA-version 0.8.0

Key features of the geobase package:

• 🔢 enums for geospatial coordinate and geometry types
• 🌐 geographic positions and bounding boxes (longitude-latitude-elevation)
• 🗺️ projected positions and bounding boxes (cartesian XYZ)
• 🏗️ coordinate transformations and projections (initial support)
• 📅 temporal data structures (instant, interval)
• 📃 geospatial data writers for features, geometries, coordinates, properties:
  • 🌎 supported formats: GeoJSON
• 📃 geospatial data writers for geometries and coordinates:
  • 🪧 supported formats: WKT

Key features of the geocore package:

• 🚀 geospatial data structures (geometry, features and metadata)
• 🌐 geographic coordinates (longitude-latitude)
• 🗺️ projected coordinates (cartesian XYZ)
• 🔷 geometry primitives (bounds or bbox, point, line string, polygon)
• 🧩 multi geometries (multi point, multi line string, multi polygon, geometry collections)
• ⭐ feature objects (with id, properties and geometry) and feature collections
• 🌎 GeoJSON data parser
• 🪧 WKT
  (Well-known text representation of geometry) data parser

Key features of the geodata package:

• Client-side data source abstraction for geospatial feature service Web APIs
• Implementations to read geospatial features
  • GeoJSON features from Web APIs or files
  • OGC API Features based services (partial support)

BETA-version 0.7.0 with deps on new data objects of attributes package

• Mostly relatively small changes, but required (breaking) changes due
  • updated dependency 0.7.1 on attributes
    • required changes visible in Feature class and GeoJSON factories
• Official Dart lint rules applied with recommend set

BETA-version 0.6.0 with lint rules updated, repository changes and other refactoring

• Some code packages were moved out from this repository to the new dataflow repository as they are not geospatial at all
  • attributes
  • datatools
• Lint rules and analysis options updated
• Also implicit-casts and implicit-dynamic set to false requiring code changes

BETA version 0.5.0 with stable sound null-safety

• BETA version 0.5.0 with stable sound null-safety on all packages requiring the stable Dart 2.12

BETA-version 0.5.0 with datatools and geodata refactored

• the first BETA version 0.5.0
• preparing to stabilize null-safety features as described by the official blog:
  • Preparing the Dart and Flutter ecosystem for null safety
• datatools totally refactored
  • Fetch API abstraction (content, control data, exceptions, fetch interface).
  • Fetch API binding to HTTP and HTTPS resources (using http).
  • Fetch API binding to file resources (based on dart:io).
• geodata also refactored, now with data source implementations:
  • GeoJSON features from Web APIs or files
  • OGC API Features based services
• other cleanup on other packages too

Pre-release 0.4.0 with new attributes and datatools packages

The new main structure of this repository containing the following Dart code packages:

• attributes : Data structures and utilities for identifiers, value maps and dynamic data objects.
• datatools : Metadata structures and utilities to access Web APIs.
• geocore : Geospatial data structures (features, geometry and metadata) and utilities (GeoJSON parser).
• geodata : A geospatial client reading OGC API and other data sources.

Also many other code refactorings and new features. See changelog of each package.

Pre-release 0.3.0 with GeoJSON support

geocore main changes:

• GeoPoint sub classes to support representing also M-coordinate
• Empty geometry to map null geometries (ie. from GeoJSON) to such instance
• Multi geometry: MultiPoint, MultiLineString, MultiPoint, GeometryCollection
• Feature class changes: FeatureId, Feature, FeatureSeries, FeatureCollection
• Factory abstraction for creating geometries, features and feature collections
• Factory implementation for GeoJSON, initial version, not full coverage

geodata main changes:

• Adaptation to the geocore changes: feature, collection and geometry classes
• Now uses GeoJSON parser from the geocore package
• Updated example code

Pre-release 0.2.0 with more geometry classes and features

Main changes on Dart packages:

• geocore: more geometries, custom iterable classes, features and collections
• geodata: initial version to read items resource (features) from OGC API Features

Initial pre-release 0.1.0 with Dart null-safety

Two Dart packages with null-safety design:

• geocore (Geospatial data structures and geometry classes for Dart.)
• geodata (A geospatial client reading OGC API and other data sources)
