vector library

Text and binary formats for vector data (features, geometries, coordinates).

Key features:

positions, position arrays and bounding boxes based on coordinate arrays
text format writers and parsers for features, geometries, coordinates, properties:
- supported formats: GeoJSON
text format writers and parsers for geometries and coordinates:
- supported formats: WKT
binary format encoders and decoders for geometries:
- supported formats: WKB

This libary exports a subset of package:geobase/geobase.dart.

Usage: import package:geobase/vector.dart

Classes

ContentDecoder: An interface to decode content from a text or binary format.
ContentEncoder<Content extends Object>: An interface to encode Content into a text or binary format.
DefaultFormat: The "default" text format for coordinate and geometry objects.
GeoJSON: The GeoJSON text format for coordinate, geometry and feature objects.
GeoJsonConf: Optional configuration parameters for formatting (and parsing) GeoJSON.
SimpleGeometryContent: An interface to write simple geometry data to format encoders and object builders.
TextReaderFormat<Content extends Object>: An interface to access text format decoders (readers) for Content.
TextWriterFormat<Content extends Object>: An interface to access text format encoders (writers) for Content.
WKB: The Well-known binary (WKB) format, see geometry for accessing the format.
WKT: The WKT text format for coordinate and geometry objects.
WktLikeFormat: The WKT (like) text format for coordinate and geometry objects.

BinaryFormat<Content extends Object>: A mixin to access binary format encoders and decoders for Content
CoordinateContent: An interface to write coordinate data to format encoders and object builders.
FeatureContent: An interface to write geospatial feature objects to format encoders and object builders.
GeometryContent: An interface to write geometry data to format encoders and object builders.
TextFormat<Content extends Object>: A mixin to access text format encoders and decoders for Content.

WriteFeatures = void Function(FeatureContent output): A function to write geospatial feature objects to output.
WriteGeometries = void Function(GeometryContent output): A function to write geometry data to output.
WriteSimpleGeometries = void Function(SimpleGeometryContent output): A function to write simple geometry data to output.
