node-ogr

OGR bindings for node.

var ogr = require('ogr');

var driver = ogr.getDriverByName('ESRI Shapefile');
var layer  = driver.open('../test/support/valid_shapefile.shp').getLayer(0);

console.log(layer.getNextFeature().getGeometry().exportToJSON());

Requirements

• node >= 0.6.0
• GDAL 1.9.x

Installation

First install GDAL http://trac.osgeo.org/gdal/wiki/DownloadSource

As of right now you can only install it locally since it's not on npm yet.

git clone git://github.com/zhm/node-ogr.git
cd node-ogr
make configure
make

Then you can run the tests (the tests require CoffeeScript to be installed, npm install -g coffee-script)

make test

or

npm test

Examples

There are examples in /examples that show some basic usage. One connects to PostGIS and outputs centroids to a csv. The best documentation for right now is the unit tests in /test and the OGR API reference.

When running locally, you might need to specify $NODE_PATH so node knows where to find the binding. See the run script in the /examples directory for more information. The other option is to explicitly pass the path of ogr.node to require.

Notes

Don't use this in server code. All of the methods are synchronous for now until I determine which methods should make use of the node threadpool. The API will change when async methods are added because they will become the default.
