Bindings to GDAL (Geospatial Data Abstraction Library)
Read and write raster and vector geospatial datasets straight from Node.js with this native GDAL binding. GDAL 1.11.1 (GEOS 3.4.2, Proj.4 4.8.0) comes bundled, so node-gdal will work straight out of the box.
$ npm install gdal --save
To link against shared libgdal, install using:
# requires libgdal-dev (debian: sudo apt-get install libgdal-dev)$ npm install gdal --build-from-source --shared_gdal
var gdal = require"gdal";var dataset = gdalopen"sample.tif";console.log"number of bands: " + datasetbandscount;console.log"width: " + datasetrasterSizex;console.log"height: " + datasetrasterSizey;console.log"geotransform: " + datasetgeoTransform;console.log"srs: " + dssrs ? dssrstoWKT : 'null';
var gdal = require"gdal";var dataset = gdalopen"sample.shp";var layer = datasetlayersget0;console.log"number of features: " + layerfeaturescount;console.log"fields: " + layerfieldsgetNames;console.log"extent: " + JSONstringifylayerextent;console.log"srs: " + layersrs ? layersrstoWKT : 'null';
- This binding is currently not async, so it will block node's event loop. This will be changing in the future (#18). In the meantime, be very careful (or avoid) using it in server code.
Before submitting pull requests, please update the tests and make sure they all pass.
