GeoDLL is a highly accurate Geodetic Development Kit/ Geodetic Function Library with worldwide 2D and 3D coordinate transformation, datum shift, meridian convergence, extra parameter, and support for Helmert, NTv2, HARN, INSPIRE, EPSG, DEM, and more.
One of the main advantages of GeoDLL is that it enables developers to include professional Coordinate Transformations in their programs, supporting a broad range of Coordinate and Reference Systems, including the current and historical Systems of all countries of Europe, The European ETRS89 systems forced by INSPIRE, The US and Canadian NAD, NTv2, HARN and SPCS Coordinate Reference Systems, The Coordinate Reference Systems of most countries of all continents, The Coordinate Reference Systems of Germany, Austria and Switzerland incl. NTv2, The Geographic coordinates in different notations and Cartesian coordinates, Worldwide NTv2 gridfile supported Coordinate Transformations, Worldwide used numeric and alphanumeric Coordinate Systems, Most of EPSG supported Coordinate Reference Systems, ITRS annual realizations or WGS84 epochs for GPS measurements, WGS84 Coordinate Transformations in consideration of the continental drift, User-defined Coordinate Systems, Reference Systems, and earth ellipsoids, Meridian Convergence, Origin Center Meridian, and Geographical Point Coordinates.
GeoDLL's development is based on the Microsoft Visual Studio, utilizing the power of C/C++ programming languages, ensuring fast performance, compact code, and high stability. Overall, GeoDLL is a robust and reliable solution for developers in need of extensive Geodetic Function Library for their Geodetic and GIS development projects.
