gdalClip

Clip geometries between two datasets while maintain the attributes from both.

Dependencies

• gdal
• uuid

Setup

npm install gdalclip

Usage

const data = gdalClip.processData(<clipFeature>, <inputFeature>, <outputName>, <outputFormat>);

• clipFeature: Must be Polygon or MultiPolygon.
• inputFeature: Polygon/MultiPolygon/Point/MultiPoint/Linestring/MultiLinestring
• outputName: Path and output name for the new file [DEFAULT: shapefile with random name].
• outputFromat: Output format that wil be used to save the data [DEFAULT: ESRI Shapefile].

Sample Usage

const gdalClip = require('gdalclip');
const gdal = require('gdal');
 
const getFeatures = dataset => gdal.open(dataset).layers.get(0);
 
const baseData = getFeatures('path/to/baseData.shp');
const clipData = getFeatures('path/to/clipData.shp');
 
gdalClip.processData(clipData, baseData, 'path/to/outputData.shp', 'ESRI Shapefile');

Allowed Outputs

Tested with the most common outputs that are listed on gdal. Message me on GitHub if you need some help or find some bug.

You can also use vsimem to save the data temporary on the memory. So the command would be something like:

const singleParts = gdalClip.processData.processData(inputLayer, '/vsimem/temp_output.shp', 'ESRI Shapefile')
