edsc-geo is a utility library for working with spherical
coordinates, polygons, and arcs in Javascript.
The edsc-geo plugin was developed as a component of
Earthdata Search.
npm install @edsc/geo-utils
| Method | Description | Input | Output |
| :----: | ----------- | ----- | :----: |
| dividePolygon | Given a list of latlngs constituting a polygon, returns an object: {interiors: [...], boundaries: [...]} | Array of latlngs | {interiors: [...], boundaries: [...]}
| gcInterpolate | Given two points, returns their midpoint along the shortest great circle between them. The two points may not be antipodal, since such a midpoint would be undefined | Two points, objects with lat/lng keys | Object with lat/lng keys
| getShape | Takes an array of lat/lng pairs and returns array of objects with lat/lng keys | Array of lat/lng pairs ['10,0','20,10'] | Array of objects with lat/lng keys [{ lat: 0, lng: 10 }, { lat: 10, lng: 20 }]
| makeCounterClockwise | Ensures that latlngs is counterclockwise around its smallest area | Array of latlngs | Array of latlngs
| mbr | Finds the minimum bounding rectangle of the provided spatial | Spatial object containing boundingBox, circle, point or polygon spatial | { swLat, swLng, neLat, neLng }
| splitListOfPoints | Splits a string of points on every other comma | '10,0,20,10' | ['10,0','20,10']
