GeoDLL English

This is a DLL that provides Geodetic functions support.

The DLL module comes with a complete development tool description and a user manual that describes functions individually. The library covers coordinate and reference Systems usually used in Geodetic surveys. NTv2 is supported in the DLL package. Digital elevation models work is facilitated by the functions provided in the library. GeoDLL function library comes with support for world-wide 2D and 3D Coordinate Transformation, datum shift, Helmert and Molodenski Parameters, NTv2, INSPIRE, EPSG, Digital Elevation Model (DEM), distance calculation and others with high accuracy and is available as 32Bit and 64Bit DLL and as C++ source code. Reference System Transition, meridian strip changing, user defined Coordinate and Reference Systems, NTv2 handling and BeTA2007 support, Direct / Inverse solutions, map function and geodetic converting functions are other functions included. A complete coverage of EPSG-codes of the North American continent is included.

These geodetic functions of GeoDLL can be linked to programs written in C, C++, C#, Java, Delphi, MS-Access, Visual Basic, CA-Visual Objects and other programming languages. The downloadable package comes with source code for many commonly used programming languages. Professional Coordinate Transformations is one of most commonly used function in geodetic work. This library supports the following, the current and historical Systems of all countries of the European Union (EU), coordinate reference systems of the European non-EU countries, European ETRS89 systems forced by INSPIRE, the US and Canadian State Plane Coordinate Systems (SPCS), coordinate Reference Systems of most countries of all continents, etc. This is a very good tool for use by Geodetic professional.

GeoDLL supports the development of geodetic software on various platforms by providing geodetic functions. GeoDLL contains precise calculations on the themes 2D and 3D coordinate transformation, geodetic datum shift and reference system converting, meridian strip changing, user defined coordinate and reference systems, distance calculations, Digital Elevation Model, NTv2 handling and BeTA2007 support, Direct / Inverse solutions, map function and geodetic converting functions. The most important application of GeoDLL is to include professional coordinate transformations in own programs. These coordinate and reference systems are supported: 1. The current and many historical coordinate and reference systems of all countries of the European Union (EU) including the eastern extensions and the systems of the European non-EU countries. 2. The European ETRS89 systems forced by INSPIRE with respect to the continental drift. 3 .The US and Canadian State Plane Coordinate Systems (SPCS) and other systems of the North American continent. 4. Many coordinate and reference systems of the countries of all continents and the world-wide used coordinate and reference systems. 5. World-wide NTv2 grid file supported coordinate transformations. 6. The coordinate and reference systems of the old and new German Federal States, the 40 Prussian Soldner Land Registers, the German 'Lagestatus', special reference systems of the German Federal States and BeTA2007. 7. User defined coordinate systems, reference systems and earth ellipsoids. GeoDLL comes with extensive documentation and is supplied as DLL file or as C++ source code for 32bit and 64bit architectures. The DLL works with most programming languages and it can be used with Microsoft Office programs. The DLL is written in C++ and was developed with Microsoft Visual Studio 2010. Thus very fast performance, compact code and high stability are assured. The functions of GeoDLL are prepared for multithreading.
