Empty coordinates #169
Description
Null coordinates, right not geojson geometries are defined as arrays of Position
but looking at the spec it seems that we should allow empty coordinates 😬
o A GeoJSON Geometry object of any type other than
"GeometryCollection" has a member with the name "coordinates".
The value of the "coordinates" member is an array. The structure
of the elements in this array is determined by the type of
geometry. GeoJSON processors MAY interpret Geometry objects with
empty "coordinates" arrays as null objects.
