Hello,
GeoDLL is available in a new version and can be downloaded from my website
now. For those of you who do not know GeoDLL yet, I have made a short
description here.

GeoDLL supports the development of geodetic software on various platforms by
providing geodetic functions. GeoDLL contains precise functions of the
themes 2D and 3D coordinate transformation, geodetic datum shift and
reference system convertion, meridian strip changing, user defined
coordinate and reference systems, distance calculation, Digital Elevation
Model, NTv2 handling, Direct / Inverse Solutions and map function.

Detailed information about GeoDLL and the ability to download a free trial
version is available here: http://www.killetsoft.de/p_gdla_e.htm.

GeoDLL makes possible to perform professional grade coordinate
transformations in own programs:

1.The current and many historical coordinate and reference systems of all
countries of the European Union (EU) including the eastern extensions from
2004 and 2007 and the systems of the European non-EU countries.

2.The INSPIREŠ supported European ETRS89 systems.

3.The US and Canadian State Plane Coordinate Systems (SPCS) on NAD27 and
NAD83 and other coordinate and reference systems of the North American
continent.

4.The coordinate and reference systems of the Australasian continent.

5.Many coordinate and reference systems of the countries of other
continents.

6.World-wide NTv2 grid file supported coordinate transformations.

7.All world-wide coordinate and reference systems in current use.

8.The German coordinate and reference systems of the old and new federal
states, the 40 Prussian Soldner Land Registers, the German 'Lagestatus', and
exact reference systems of the German federal states.

User coordinate systems, local reference systems and earth ellipsoids can be
defined, based on the coordinate system parameters, the semi axes of the
earth and seven Helmert or three Molodenski datum parameters.

GeoDLL comes with extensive documentation and is supplied as a DLL file or
as C++ or CA-Visual Objects source code. The functions of GeoDLL are
suitable for multithreading. The DLL is written in the C++ language. That
gives very fast performance, compact code, and high stability in use.

WINDOWS operating system allows building of function libraries intended for
use by applications, the so-called Dynamic Link Libraries. The application
uses functions stored in the DLL by making a DLL call. The language used for
developing applications that call functions of the DLL is not important. It
could be C, C++, C#, Delphi, MS-Access, Visual Basic, Java, .NET, Visual
Objects or other. Therefore GeoDLL is delivered with examples and interface
source code for many commonly used programming languages.

Regards, Fred
