Create hundreds of control points automatically
from reference image using auto-register
Geospatial data that you obtain for your projects may have georeference information that is not accurate enough for your objectives and may contain spatial distortions that require rectification. The Georeference process in TNTmips lets you create, import, or edit georeference information quickly and easily for any type of geospatial data (image or geometric) including external files in many formats. Images and geometric objects with different coordinate reference systems can be displayed together in TNTmips or you can permanently reproject them to a common reference system. You can rectify spatial distortions in images using various georeference models and orthorectify satellite images using an RPC model and a DEM.
