Download NTv2Creator 5.15 – Descargar

NTv2Creator geosoftware provides a powerful tool for modeling accurate NTv2 files from identical points in two different reference systems. The software analyzes two files with identical points and suggests boundaries and mesh sizes that can then be changed manually. Finally, a highly accurate NTv2 file is generated using small-scale three-dimensional 7-parameter Helmert transformation around each grid point and subsequent Natural Neighbor Interpolation for residual gap distribution. NTv2Creator offers three different mathematical models for modeling NTv2 files.
At the beginning of processing, the coordinates of the identical points are tested for outliers and deviations using statistical methods. Then all grid points are calculated. To calculate a grid point, the program NTv2Creator collects all identical points from the point files of the source reference system and the target reference system, which lie in a certain radius around the grid point. With these points, a small spatial three-dimensional 7 parameter Helmert transformation is performed. During the subsequent coordinate transformation of the grid point to the source reference system, the Helmert parameters determine the coordinate of the same grid point in the target reference system. To increase the accuracy, the Natural Neighbor interpolation is used for the distribution of remaining gaps. The difference between the coordinates of the grid point in both reference systems is entered as a shift value in the NTv2 file. The calculated shift values ​​include compensation of regional and local stresses, and they take into account the different dimensions and bearings of the ellipsoids used in both reference systems.
