NTv2 Toolbox

NTv2Tools Geosoftware provides a toolbox for developing and processing of NTv2 files in binary and ASCII formats. With the included tools NTv2 files can be analyzed and graphically or textual displayed, they can be converted to other file formats and areas of them can be extracted to new NTv2 files.

NTv2Tools - Version 1.02 - Last update on 11 July 2018

NTv2 grids

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 points from one coordinate reference system to another with very high accuracy. An NTv2 file contains one or more quasi-rectangular coordinate grids 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.

NTv2Tools - Detailed Program Description
Tools for developing and processing of NTv2 files in Binary and ASCII Formats

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. Soon also new NTv2 grids can be added to existing NTv2 files. The following processings are possible:

  1. Analyze NTv2 file
  2. Display NTv2 grids and subgrids
  3. Display NTv2 activity scopes (normal and polygonal)
  4. Convert NTv2 ASCII file to NTv2 Binary file
  5. Convert NTv2 Binary file to NTv2 ASCII file
  6. Extract area from NTv2 file

Alternatively, the processings listed here can be embedded as a DLL with the Geodetic Development Kit engineered by KilletSoft into your own programs. Detailed information about all processings can be found at the following links:

  1.  Worksheet "Tools for analyzing and processing of NTv2 files"
  2.  Geodetic Development Kit - Function group "NTv2 Tools"

NTv2 files that have been previously equipped with Polygonal Validity Scopes to map a polygonal boundary instead of a quasi-rectangular area in the NTv2 grids are supported by the NTv2Tools program. The Polygonal Validity Scopes realized in the NTv2 files is taken into account for all types of processing and is displayed in all graphical views. Detailed information on this topic can be found at the following links:

  1.  Program description of the program NTv2Poly
  2.  Worksheet "Polygonal Validity Scopes"

The program has a user-selectable multi language interface and comes with extensive online help. The program can be run on most common networks and it is possible to use Terminal Services on WINDOWS Servers. In case of a network installation the clients are installed automatically by the program.

Multilanguage support

The program NTv2Tools is equipped with a modern graphical user interface of which handling is to understand intuitively. For each window detailed help texts can be shown. The detailed electronic documentation of the program NTv2Tools is available in both English and German language. However, the user interface can be represented in many languages. For this purpose, external language files are used. When starting the program, it notes which language files are available in the calling directory. The found languages then are provided for selection in a list box. By  creating new language files, new languages can be added to the program NTv2Tools at any time.

Network ability

The program NTv2Tools can be run on most common networks. The client installations works automatically. It is possible to use Terminal Services on WINDOWS Servers like e.g. "Citrix Terminal Server".

Pricing, ordering and licensing

Pricing and ordering information can be found in the  Price list. For available licensing options have a look to the  License page. Order the program with the electronic  Order Form.

Download of the test version

The free test version of the program with a detailed user manual can be  downloaded as ZIP packed file by the Internet. For unpacking the download file you need an unzip program, which you can download  from this side.

KilletSoft Logo Translators wanted!
The programs TRANSDAT and SEVENPAR support language files for the programs interface. Since the language dependent texts are managed in external files,  new languages can be added at any time by creating new language files. Everybody who is interested can translate a new language file into his native language for himself and all users.
