class CoordTransform(source, target)
Represents a coordinate system transform. It is initialized with two SpatialReference, representing the source and target coordinate systems, respectively. These objects should be used when performing the same coordinate transformation repeatedly on different geometries:
1 2 3 4 | >>> ct = CoordTransform(SpatialReference('WGS84'), SpatialReference('NAD83'))>>> for feat in layer:... geom = feat.geom # getting clone of feature geometry... geom.transform(ct) # transforming |
