Spatial Data Interview Question:

What is Map Projection Transformations?

Submitted by: Murtaza

Map Projection Transformations functionality concerns the transformation of data in geographic coordinates for an existing map projection to another map projection. Most GIS software requires that data layers must be in the same map projection for analysis. Accordingly, if data is acquired in a different projection than the other data layers it must be transformed. Typically 20 or more different map projections are supported in a GIS software offering.
