NTv2Tools is a program specialized in analyzing NTv2 data for the purpose of transforming the points from one coordinate reference system to another with high fidelity and accuracy. The output information is displayed on both the text and graphs and you can convert it to ASCII or binary, depending on how you intend to further analyze it using other third-party software solutions.

It is important to note that the app includes several functions that can come in handy for anyone working with maps and coordinates. More precisely, the tool enables you to analyze the NTv2 files, display the grids, subgrids and activity scopes, both the normal and polygonal ones, extract an area from the file and the conversion to file formats that can be used with other apps.

According to the developer, all calculations made by the tool are strictly and solely based on formulas and no approximations are not used. This is possible mainly because of the nature of the NTv2 files; in fact, if the files have been equipped with Polygonal Validity Scopes to map a boundary instead of the standard quasi-rectangular area specific to grids. Nevertheless, for enhanced convenience, the app graphically displays this type of information following the analysis.
