NoCRS
is required because no crs
attribute in a GeoJSON feature is NOT the same thing as
a null crs
attribute. no crs
value implies the default CRS, while a null CRS means
you cannot assume a CRS, null will mapped to NoCRS
while a non-existent attribute will
be mapped to a Nothing
Maybe
value
data BoundingBoxWithoutCRS Source #
See Section 4 Bounding Boxes of the GeoJSON spec, The length of the list/array must be 2*n where n is the dimensionality of the position type for the CRS with min values first followed by the max values, wich both the min/max sets following the same axis order as the CRS, e.g for WGS84: minLongitude, minLatitude, maxLongitude, maxLatitude The spec mentions that it can be part of a geometry object too but doesnt give an example, This implementation will ignore bboxes on Geometry objects, they can be added if required.

Functions
stripCRSFromPosition :: GeoPosition -> GeoPositionWithoutCRS Source #
the GeoPosition
is a bit special in that when you convert it to GeoJSON,
it will lose the CRS info attached to it and cannot be read back in
from the GeoJSON. Hence it is ineligible for the FromJSON
type class,
so this function will strip it down to a GeoPositionWithoutCRS
, which is eligible
defaultCRS :: CRSObject Source #
The default CRS according to Section 3 Coordinate Reference System Objects is WGS84 which I believe, from http://spatialreference.org/ref/epsg/4326/ which translates to this in JSON: http://spatialreference.org/ref/epsg/4326/json/) is represented thus:
