geocore 0.3.0-nullsafety.0

Geospatial data structures (features, geometry and metadata) and utilities (GeoJSON parser) for Dart.

0.3.0-nullsafety.0

• Alpha version 0.3.0 with breaking changes compared to 0.2.0
• New dependency: fixnum (^1.0.0-nullsafety.0) for Int64 (Dart VM / JavaScript)
• New constructors on Point and GeoPoint for creating points from coordinates
• GeoPoint sub classes to support representing also M-coordinate
• New enumerated type: enum CRSType { geographic, projected, local }
• 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
  • FeatureCollection, Feature
  • Point, LineString, Polygon
  • MultiPoint, MultiLineString, MultiPoint
  • GeometryCollection
• Refactoring also some other constructors for consistent naming conventions
• Some tests added also to test parsing GeoJSON data

0.2.0-nullsafety.0

• Alpha version 0.2.0 with breaking changes compared to 0.1.0.
• More geometries: LineString (any line string or linear ring), Polygon
• Custom Iterable interface and sub implementation: Series, SeriesView
• Geometry series: GeometrySeries, PointSeries, LineStringSeries, PolygonSeries
• Features and collections: Feature, FeatureSeries

0.1.0-nullsafety.2

• Small fixes on README.md

0.1.0-nullsafety.1

• Small fixes on links of pubspec.yaml

0.1.0-nullsafety.0

• Initial pre-release version, the API of the library is not stable
• Designed for null-safety (requires sdk: '>=2.12.0-0 <3.0.0')
• Uses as dependency: Equatable (^2.0.0-nullsafety.0)
• Cartesian points using doubles: Point2, Point2m, Point3, Point3m
• Cartesian points using integers: Point2i, Point3i
• Geographical points using doubles: GeoPoint2, GeoPoint3
• Geographical camera: GeoCamera
• Geographical bounds: GeoBounds
• Coordinate reference systems: CRS class with two predefined identifiers
• Temporal coordinates: Instant, Interval
• Geospatial extent: Extent
