0.3.0

✨ New: Data structures for simple geometries, features and feature collections. ✨ New: Support for Well-known binary (WKB). Text and binary data formats, encodings and content interfaces also redesigned.

⚠️ Breaking changes:

• Content interfaces, content encoders and text formats redesigned
• Rename writers and content interfaces to generalize #127
• Geometry content written with more specific methods #128
• Allow coordinate value arrays along with position arrays on content interfaces #129
• Simplify Coords enum #130
• Type changes on projections and adapters #151
• Move "basic transforms" from geobase to geocore #152

🧩 Features:

• Combine writers and parsers for formats (GeoJSON, WKT) consistently #125
• Add WKB encoding/decoding support #115
• Text and Binary outputs on writers #126
• Text and Binary outputs on decoders #132
• Coordinate order on box and position consistently #134
• Positions as iterable of coordinate values on geobase #136
• PositionData access (on lists or buffers) #137
• new mini library "transforms" and "projections"
• Simple geometry data structures on geobase #133
• Feature data structures on geobase #138
• GeoJSON text decoder building new geometry and feature data structures on geobase #139(https://github.com/navibyte/geospatial/issues/139)
• Equals, hashCode and toString for geometries and features on geobase #143
• Encode / write methods directly from geometry and feature classes on geobase #144
• Decode GeoJSON and build data structures using new data structures by geobase #140
• Handle explicit and implicit bounds in geometries and features on geobase
• Handle projections and transforms of geometries and features on geobase #142

🛠 Refactoring:

• Optimize reading from iterable of coordinate values #131
• Feature properties and data maps as Map<String, dynamic> instead of Map<String, Object?> #147
• Refactor fromJson / toJson methods on model classes #150

🛠 Maintenance:

• Lint rules without old strong mode, but with new "stricter type checks" #148
• Mark internal classes with @internal #149

📚 Documentation

• Documentation about content builders, geometries and features on geobase #145

0.2.1

🐛 Bugs fixed:

• Ambiguous reexports on geobase 0.2.0 with constants #122

0.2.0

✨ New: Tiling schemes and tile matrix sets (web mercator, global geodetic). Also other improvements on coordinates, and refactorings on the code structure.

🧩 Features:

• Mini-libraries for geobase #109
• Conversion between WGS84 (lon-lat) and Web Mercator Quad tile matrix set #57
• MapPoint2i renamed to ScalableXY, and implementing Projected and Scalable #116
• Use OGC specified screen pixel size / ppi when calculating scale denominator #119
• Add World CRS84 TileMatrixSet #114
• Add zoomIn, zoomOut and zoomOut to Scalable2i #121

🛠 Maintenance:

• Upgrade to Dart 2.17 #105
• Apply very_good_analysis 3.0.0+ lint rules #104
• Restructure code folders on geobase package #107

0.1.1

🧩 Features:

• Create position instances from num iterables or text #101
• Distance (haversine) between geographic positions #102
• Create box instances from num iterables or text #103

0.1.0

Initial version with some code originating from geocore 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
