Seven Parameters Calculation File Format
Control points should have at least three pairs and should be saved correspondingly in source and targeted coordinate files. Supported coordinate formats are spatial Cartesian coordinate system (X, Y, Z) and geographic coordinate system (B, L, H) (in the format of degree or degree:minute:second). Each point should be written in one row, and the geographic coordinates should be written in format of latitude, longitude, and height, separated by comma.
