    gdal-next

    2.8.0 • Public • Published

    Fork Notes

    This project is a fork of https://github.com/naturalatlas/node-gdal that:

    • Updates native dependencies (GDAL/PROJ/GEOS) to latest versions
    • Updates the build system/JS/prebuilds for newer versions of node
    • Adds support for more formats
      • GPKG, sqlite, OSM, MBTiles, MVT
    • Adds additional features
    • Adds async support for raster data + opening/parsing files
    • Adds support for vsimem files using buffers
    • Fixes loads of bugs, performance issues, and more

    See the ROADMAP for more info about the future of this fork. All thanks and credit goes to the original maintainers!

    Breaking Changes

    • With PROJ 6+, the order of coordinates for EPSG geographic coordinate reference systems is latitude first, longitude second. If you don't want to make large code changes, you can replace code like gdal.SpatialReference.fromEPSG(4326) with gdal.SpatialReference.fromProj4('+init=epsg:4326')

    NPM version Installs Build Status

    Read and write raster and vector geospatial datasets straight from Node.js with this native GDAL binding. To get started, browse the API Documentation or examples.

    $ npm install gdal-next --save

    By default all dependencies are the latest versions and bundled out of the box, but if you would like to link against a pre-installed gdal you can use these flags when installing:

    # requires libgdal-dev (debian: sudo apt-get install libgdal-dev)
    $ npm install gdal-next --build-from-source --shared_gdal

    Sample Usage

    Raster

    const gdal = require("gdal-next")
    const dataset = gdal.open("sample.tif")
    
    console.log("number of bands: " + dataset.bands.count())
    console.log("width: " + dataset.rasterSize.x)
    console.log("height: " + dataset.rasterSize.y)
    console.log("geotransform: " + dataset.geoTransform)
    console.log("srs: " + (dataset.srs ? dataset.srs.toWKT() : 'null'))

    Vector

    const gdal = require("gdal-next")
    const dataset = gdal.open("sample.shp")
    const layer = dataset.layers.get(0)
    
    console.log("number of features: " + layer.features.count())
    console.log("fields: " + layer.fields.getNames())
    console.log("extent: " + JSON.stringify(layer.extent))
    console.log("srs: " + (layer.srs ? layer.srs.toWKT() : 'null'))

    Notes

    • Currently only raster operations are async, everything else will block Node's event loop. The module is not worker-thread compatible so we recommend using worker-farm to push expensive operations to a seperate process.
