Geospatial data structures, tools and utilities for Dart and Flutter.
Add support for parsing and serializing MGRS coordinates provided by the [mgrs_dart](https://pub.dev/packages/mgrs_dart) package. See also #52. [mgrs_dart](https://pub.dev/packages/mgrs_dart): _Utility for converting between WGS84 lat/lng and MGRS coordinates._
Background * [Error vs. Exception in Dart](https://stackoverflow.com/questions/17315945/error-vs-exception-in-dart) * [Error vs Exception? Why both? When to use which? When to subclass which?](https://groups.google.com/a/dartlang.org/g/misc/c/lx9CXiV3o30/m/s5l_PwpHUGAJ) Bob Nyström (2013): * _Error and its subclasses are...
https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry Now (at least some level of) support for: * Point, MultiPoint * LineString, MultiLineString * Polygon, MultiPolygon * GeometryCollection However NO support for these, and not yet even planned...
*Plan updated 2024-04-16* Implementation for v.1.1.0 * Support decoding also EWKT data (ignoring an optional srid). * Utilities to decode a coordinate type and SRID from WKT text. * A...
* Coordinate reference system (`CRS`) identifiers * Enhanced support for **most** common CRS values * CRS properties on geometries (should every class have or only collections?)
Support for [OGC Features and Geometries JSON](https://github.com/opengeospatial/ogc-feat-geo-json). The spec defines: * _include the ability to use Coordinate Reference Systems (CRSs) other than WGS84_ * _allow the use of non-Euclidean metrics,...
These points are all pretty close (usually
Built-in projection between WGS84 geographic coordinates and Web Mercator projected (metric) coordinates now clips projected coordinates to the range [-20037508.34, 20037508.34]. This corresponds to the Web Mercator tiling scheme clipping...
Enhancing further implementations of #57 and #114. "Web Mercator Quad" or "Spherical Mercator" or "Pseudo-Mercator" was already implemented in #57. It's most commonly used projection and tile matrix set in...
