For type "LineString", the "coordinates" member must be an array of two or more positions. A LinearRing is closed LineString with 4 or more positions. The first and last positions are equivalent (they represent equivalent points). Though a LinearRing is not explicitly represented as a GeoJSON geometry type, it is referred to in the Polygon geometry type definition.

Examples

'{
   "type": "LineString",
   "coordinates": [
      [100.0, 0.0],
      [101.0, 1.0]
   ]
}'
#> [1] "{\n   \"type\": \"LineString\",\n   \"coordinates\": [\n      [100.0, 0.0],\n      [101.0, 1.0]\n   ]\n}"
