Usage

Click here for an online demo

The script (will) contain the following API methods:

lineString(polygon, (angle), (minDistance))

where

polygon a GeoJSON feature (GeoJSON geometries need to be converted to features first)

angle the maximal allowed turning angle in degrees, defaults to 30 deg

minDistance the minimum distance in meters between two coordinates used for angle comparison, defaults to 10 m.

Example

const vorgewende = require('vorgewende')
const fs = require('fs')

let plot = fs.readFileSync('somePlotPolygonFeature.geojson')
let headlands = vorgewende.lineString(plot) // will contain all headlands as GeoJSON lineString features

Returns

An array of GeoJSON lineString features representing each headland.

polygons(polygon, headlandWidth, (angle), (minDistance))

where

headlandWidth Width of each headland in meters, typically equal to (half) the working width of the sprayer used.

else see lineString parameter description.

Returns

An array of GeoJSON polygon features representing each headland.
