A JavaScript library of spatial predicates and functions for processing geometry

Package Exports

  • jsts
  • jsts/dist/jsts.min
  • jsts/src/org/locationtech/jts/geom/Geometry
  • jsts/src/org/locationtech/jts/operation/buffer/BufferOp

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (jsts) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

JSTS

Build Status

JSTS is a JavaScript (ES6 aka. ECMAScript 2015) library of spatial predicates and functions for processing geometry conforming to the Simple Features Specification for SQL published by the Open Geospatial Consortium. JSTS is also a JavaScript port of the well established Java library JTS with a built in parser for OpenLayers 3 interopability.

The primary goal of the project is to provide web mapping applications with a complete library for processing and analyzing simple geometries but JSTS can also be used as a free standing geometry library.

JSTS was made using automatic translation of the original JTS Java source via AST to AST transformation preserving the JTS API.

An ES5 compatible build for browser use is available here.

A Google group is available for discussions.

A port of JTS Validation Suite provides additional tests.

Basic functionality is demonstrated in an example using OpenLayers 3.
