Building of a visibility area by a matrix of heights as the raster image (input from the keyboard) |
The given mode allows to define visibility areas on a map using the information from a matrix of heights. For building of the review sector the dialogue window Construction of a visibility range is used. In this window it is necessary to establish coordinates of an initial point of supervision, a corner of the review, a direction - a directional corner, distance from a point of supervision up to sector border and height of supervision in meters. For areas of the sectors intersecting there are modes: - visibility from all points; - visibility even if from one point.
In Visibility from all points mode those sites are considered seen (transparent) in a zone of the sectors intersecting which one are seen from all points of supervision. In Visibility even from one point mode those sites are considered seen (transparent) in a zone of the sectors intersecting which one are seen even if from one point of supervision. All parameters of a session (a name of a file, color, a degree of visibility of a raster etc.) are kept in file PANORAMA.INI and restored at the subsequent loading.
