NTv2 gridfiles in GSB and GSA file format

NTv2 (National Transformation version 2) datum shifts are done with grid files which comes in a binary format (GSB) and an ASCII format (GSA). It can transform coordinates between two different geodetic reference systems. The transformation provides heigh actuality and does not require ellipsoidal heights.

HARN gridfiles

The geodetic functionslibrary GeoDLL is prepared for coordinate transformations with arbitrary NTv2 gridfiles and with the American HARN gridfiles. But the HARN gridfiles of the U.S. states are available as equivalent NTv2 gridfiles. All by GeoDLL supported NTv2 and HARN gridfiles can be downloaded from this website.

Support of the NTv2 standard the Geodetic Development Kit GeoDLL

The NTv2 method uses binary files to perform accurate datum shifts from one geodetic Reference System to an other. An NTv2 file contains the differences between the two Reference Systems as geographic seconds in a grid. A bilinear interpolation is used to calculate the exact coordinates for a point in the target Reference System.

NTv2 is designed to check multiple grids for the most accurate shift information. An NTv2 file contains a low density base grid (parent). Certain areas such as cities can have high density local sub grids. The sub grids overlay portions of the base grid. If a point is within one of the high density sub grids, NTv2 will use the high density grid, otherwise, the point falls through to the low density grid.

A description of the NTv2 algorithm can be found in the following sources:

Download of the NTv2 gridfiles in binary format

Here the NTv2 binary files are listed, which are supported by the geodetic Library GeoDLL and the program TRANSDAT. In the second line always the original source is shown, from which the original NTv2 file can be downloaded and information about the associated geodetic Reference Systems are given. In the third line is a link, from which the NTv2 file can be download direct from the KilletSoft server. It is recommended to use the original NTv2 files from the original sources, because the actuality of the files stored on the KilletSoft server is not guaranteed.

Important notes:
If you want to use the here listed NTv2 files, you must necessarily note the terms and conditions of their authors! All rights and liabilities, resulting from the use of the data, bears solely the user! KilletSoft does not guarantee the accuracy of the data!

Blue marked NTv2 files have been provided by the authors only for use with KilletSoft products. Therefore, they are encrypted and only work with the Geodetic Development Kit GeoDLL and with the program TRANSDAT! These files are special licensed to KilletSoft by their authors.

The red marked NTv2 files can be ordered or purchased only directly from the authors. The Geodetic Development Kit GeoDLL and the program TRANSDAT are already prepared for the use of these NTv2 files. For the registration of the respective NTv2 file with the author KilletSoft presents the Registration Address of the author in a downloadable file.
