SEVENPAR software precisely computes parameter sets for the Spatial Helmert/Molodensky transformation. This tool facilitates accurate coordinate transformations between varied reference systems & geodetic data shifts.
The seven or three transformation parameters are computed with a set of individual identical points. These are points with known coordinates in both reference systems (geodetic datum). The program supports Cartesian coordinates, geographical coordinates, or UTM coordinates with or without ellipsoidal height using the ellipsoid dimensions. Identical measuring points of higher order can typically be inquired or referred by official institutions for measurement. The software program provides necessary ellipsoid half-axes and flattenings available in the program for the selection from lists.
The coordinates of identical points are tested extensively for outliers and deviations by various statistical procedures. The computed parameters' quality is documented by a residual matrix and through middle, maximum, and root mean square (RMS) deviations. The seven parameters of the Spatial Helmert Transformation are calculated in the three most usual standards Coordinate Frame Rotation, Position Vector Transformation, and European Standard ISO 19111. The three parameters for Molodenky parameter sets are calculated using the Standard Molodensky Transformation.
The program has a user-selectable interface available in five different languages, including English, Spanish, French, Portuguese, and German. Additionally, SEVENPAR comes with extensive bi-language online help, making it easy to use and understand. It is possible to run the software on most common networks, and it is also possible to use Terminal Services on WINDOWS Servers. Moreover, client installations are done automatically, saving time and reducing hassle.
Overall, SEVENPAR is an indispensable tool for professionals, scientists, and students who require highly precise coordinate transformations. It is efficient, user-friendly, and provides accurate results.
Version 11.04: Program faster and more stable using new development system. Outliers can be excluded from calculation. UTM coordinates of the southern hemisphere are supported. Instead of 30.000, now one million identical points can be processed. The quality of the Helmert Parameter Set is checked and documented.
