    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:

    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 INSPIREĀ© 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

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

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

    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.
