geonode

~ geonode ~

Bringing geography to node.js.

Example

var geonode = require("geonode");

var myPoint = new geonode.Geometry("POINT(1 2)");
sys.puts(myPoint.toWkt()); // "POINT (1.0000000000000000 2.0000000000000000)"

var myPolygon = new geonode.Geometry("POLYGON((0 0, 3 0, 3 3, 0 3, 0 0))");
sys.puts(myPolygon.contains(myPoint)); // "true"

Installation

$ git clone git://github.com/paulsmith/geonode.git
$ cd geonode
$ node-waf configure build

Prerequisites

• GEOS 3.1.x

TODO

In no particular order:

• Finish wrapping GEOS C API
  • Coordinate sequence functions
  • Geometry constructors
  • Some topology operations -- polygonize, line merge, etc.
  • WKB read/write
• R-Tree index (with asynchronous searches, inserts, updates, deletes)
• Prepared geometries for faster predicates (contains, intersects, within)
• GDAL OGR wrapper -- non-blocking reads from datasources
• Proj wrapper
• Better organized unit tests, more coverage
• GeoJSON read/write
• De-cargo-cult the C++, be more idiomatic
• Document API

More tk ...
