SPATIALLY

An OGS compliant GIS library for Dart

Overview

Intended as a port of a large subset of the JTS library functionality, so that web applications may benefit from access to a full suite of spatial algorithms an opertions. A full port was not desirable, as many of the extensibility options of JTS were redundant and an aim to reduce exported file size was a goal of the project

Usage

All basic utility functions are exported via

 'package:spatially/spatially.dart'

which provides implementations for the standard

  • Point
  • Linestring
  • Polygon
  • MultiPoint
  • MultiLinestring
  • MultiPolygon
  • GeometryList

GeoJSON and WKT conversion from spatially geometries is available in 'package:spatially/convert/convert.dart'

And most more advanced operations supported by JTS are exported via the various spatially modules.
