Logo Killet Software Ing.-GbR (KilletSoft) offers the Dynamic Link Library GeoDLL for embedding professional coordinate transformations and solving geodetic tasks in own Windows programs. In a further dynamic link library called BetaDLL we specifically address conversions between the reference system DHDN and ETRS89 according to the INSPIRE Directive in the light of the NTv2 standards BeTA2007. The complete functionality of BetaDLL has been included in the new version GeoDLL 15.00 since the year change.
 
In addition, GeoDLL supports the even more precise NTv2 solutions of the German federal states Bavaria, Brandenburg, Bremen, Hamburg, Hesse, Saarland, Saxony, Saxony-Anhalt and Thuringia. On the site http://www.killetsoft.de/p_gdln_e.htm NTv2 gridfiles of some federal states can be downloaded directly. Those NTv2 files have been licensed by their publishers exclusively for use with KilletSoft products. Because the gridfiles are encrypted, they only can be used by the function library GeoDLL and the program TRANSDAT for highly accurate coordinate transformations. For others, sometimes chargeable NTv2 gridfiles, links to the distributors from the respective federal states are provided on the above page. Furthermore, almost all by the European and overseas countries available NTv2 files are ready for download on that side.
 
BetaDLL in future is no longer supported and no longer distributed by KilletSoft. Thus, user of BetaDLL has no disadvantage, they get permission to acquire particularly favorable updates and upgrades of the GeoDLL function groups "Coordinate Transformations" and "NTv2 Grid Data". Quasi as a bonus, beside the previously in BetaDLL contained INSPIRE transformations with the BeTA2007 gridfile, also the high-precision NTv2 transformations of the German federal states and other countries and world-wide thousands of conventional coordinate transformations can be performed. Also the direct use of EPSG codes is possible with GeoDLL functions.
 
GeoDLL, witch runs on all modern WINDOWS operating systems, can be included into programs written, for example, in C, C#, C++, Delphi, MS-Access and Excel, Visual-Basic, Visual Objects, Vulcan and other programming languages. For use on other platforms, such as UNIX or LINUX, the C++ source code of GeoDLL is available. In order to support your developments, examples and interfaces with source code of many commonly used programming languages and a Visual Studio C++ project are included. More information and a free, in own applications linkable trial version of the Dynamic Link Library GeoDLL, you can find on the internet site http://www.killetsoft.de/p_gdla_e.htm.

KilletSoft Logo Translators wanted!
 
The latest versions of 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. Every user of the program now can compile language files for himself and our customers.
