geobase 0.3.0-dev.1

Geospatial coordinates, projections, tiling schemes and vector data support (GeoJSON, WKT, WKB) for Dart.

0.3.0

Development version 0.3.0-dev.1.

✨ New: Support for Well-know 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

🧩 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

🛠 Refactoring:

• Optimize reading from iterable of coordinate values #131

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
• 📃 geospatial data writers for geometries and coordinates:
  • 🪧 supported formats: WKT

🧩 Features:

• Separate some common features of geocore to separate common package #86
• Base interface for bounding boxes compatible with RFC7946 #87
• Separate basic point properties as position interface #84
• Formatting to text on Point (and other geometries) more flexible #81
• Coordinate types enhanced #92
• Coordinate value accessors on position classes #94
• Equality and hashcode for (Geo)Position and (Geo)Box classes #89
• Generalize and move project and transform from geocore to geobase #95
• Intersects bounds generalized on geobase #97
• Renewed GeoExtent with spatial and temporal parts #99

🛠 Maintenance:

• Upgrade to Dart 2.15 #90
