In Eucledian geometry nosotros were taught nearly the concepts of 'Point' in addition to lead trouble beingness the shortest distance betwixt 2 points. GeoJSON is an Open Standard format based on JavaScript Object Notation for representing elementary geographical (geometrical?)features. In GeoJson Point, Line in addition to Polygon are the Geometric Primitives: Point: { "type": "Point", "coordinates": [30, 10] } Line: { "type": "LineString", "coordinates": [ [30, 10], [10, 30], [40, 40] ] } Polygon: { "type": "Polygon", "coordinates": [ [[30, 10], [40, 40], [20, 40], [10, 20], [30, 10]] ] } This post service is based on GeoJSON on Wikipedia .
