SEVENPAR是一款计算Helmert变换的工具软体。 Helmert变换是计算不同系统之间的坐标变换，SEVENPAR可以精确计算出Helmert变换参数。计算出的参数可以直接输入到合适的变换软体中，如TRANSDAT坐标变换软体，或者GPS接收机的计算软体。 Helmert的七个参数是按照三个常用的标准计算的，三个标准是Coordinate Frame Rotation、 Killetsoft SEVENPAR 4.x Multilanguage | 2 MB SEVENPAR is a tool for the calculation of highly exact transformation parameters for the Spatial Helmert and Molodensky Transformation, which make possible precise coordinate transformations from one reference system into another. The determined transformation parameters can be entered directly into suitable transformation software, e.g. TRANSDAT Coordinate Transformations, or into the calculation software of GPS receivers to do exact coordinate transformations. The seven or three transformation parameters are computed with a set of individual identical points. Those are points with known coordinates in both reference systems (geodetic datum). Cartesian coordinates, geographical coordinates or UTM coordinates with or wihtout ellipsoidal height using the ellipsoid dimensions are suitable. Identical measuring points of higher order can be usually inquired or referred by the official institutions for measurement. The necessary ellipsoid half-axes and flattenings are available in the program for the selection from lists. The coordinates of the identical points are tested intensively on outliers and deviations by different statistic procedures. The quality of the computed parameters is documented by a residual matrix and by the computation of the middle, maximum and root mean square (RMS) deviations. The seven parameters of the Spatial Helmert Transformation are calculated in the three 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 multi language interface and comes with extensive online help. The program can be run on most common networks and it is possible to use Terminal Services on WINDOWS Servers. In case of a network installation the clients are installed automatically by the program.
