The basic parameters of task are entered in the frame "Settings":
- Coordinate system - determines the orientation of x, y axis. Entered coordinates x, y are not recalculated after a change of coordinate system.
- Type of terrain model and layers smoothing. Intermediate smoothing is recommended for realistic models and fast generation.
- Altitude system of task - is used just in the description of geological documentation. It has no influence on the model generation. Altitude coordinates z are not recalculated after change of altitude system.
The orthophotomap can be projected on the generated terrain model (DMT). This map is defined by three points (1, 2, 3), which are placed to the coordinates of the model. Points 1 and 2 define bottom corners of the map, point 3 defines its perpendicular distance to the bottom edge of the map (the connection between points 1 and 2). It is necessary to input points 1 and 2, the point 3 can be undefined (then the original ratio of the map is applied). The input of point 3 can also be used for mirroring of the map - in this case, points 1 and 2 define the upper edge of the map.
If we do not have a file with ortophotomap, we can load maps from public sources in the "Source Data" frame.
