NTv2Poly

The spatial software NTv2Poly replaces the rectangular activity scope contained in NTv2 files with a Polygonal Validity Scope, which is realized with an outline file in classic Shape Format. Invalid calculations outside the Polygonal Validity Scope thus can be excluded or acknowledged by a warning. Download the trial version from http://www.killetsoft.de/zip/ntv2poly.zip.
