Geosoftware with Tools for analyzing and processing of NTv2 files

Pressbox (Press Release) - Geosoftware with Tools for analyzing and processing of NTv2 files.

Tutorial for analysis, conversion and further processing of any NTv2 files in ASCII and binary format with the geospatial software NTv2Tools by KilletSoft.

The NTv2 (National Transformation Version 2) file standard was developed by the "Department of Natural Resources of Canada" in the middle nineties. Using NTv2 grid files it is possible to transform geodata from one coordinate reference system to another with very high accuracy. An NTv2 file contains one or more quasi-rectangular grids with shift values which are defined in the NTv2 headers. NTv2 files are available in ASCII and binary formatted variants. The ASCII variant is generated during the development phase of the NTv2 file, whereby all header and grid entries can be read and edited with a word processing program as plain text. For productive use in geodetic software and in GIS, the much faster binary variant with the same content is used.

The program NTv2Tools provides digital tools for developing and processing NTv2 files in binary and ASCII formats. It analyzes NTv2 files and outputs detailed information on the screen, in graphics files and in text files. The program allows conversions between the binary and ASCII formatted variants of the NTv2 files. Furthermore, areas can be extracted from NTv2 files and swapped out to new NTv2 files. This resolves the known issues with oversized NTv2 files.
