Clips the given sourceCollection against the clipGeometry and reprojects the clipped features to the targetCrs.

Parameters:

sourceCollection - the feature collection to be clipped and reprojected. If it does not have an associated CRS, the one specified by defaultSourceCrs is used.

defaultSourceCrs - if sourceCollection does not have an associated CRS, this one is used.

clipGeometry - the geometry used for clipping

clipCrs - the CRS of the clipGeometry

targetID - the ID of the resulting FeatureCollection. If null the ID of the sourceCollection is used.

targetCrs - the CRS the FeatureCollection is reprojected to. If null no reprojection is applied.

Returns:

the clipped and possibly reprojected FeatureCollection

Throws:

IllegalStateException - if the sourceCollection has no associated CRS and defaultSourceCrs is null
