Trajectory file of scenario's object movement

To prepare trajectories of objects movement in “TX3” format it is possible to use the dialog of mode "Editing metrics of selected object" (the main toolbar of GIS window). In this dialog there are various modes of modelling heights and saving into a trajectory file “TX3”. For forming a file of a trajectory at first we set a trajectory on a plane in the form of any linear object on a map, and then by means of this mode we model heights and unload into TX3.

Dialog of "Editing metrics" at constructing heights in the object metrics sets them as absolute one. If object has relative heights, then it is necessary before an unloading into the trajectory file to go the dialog "Select Object", on the metrics bookmark by the right-click to call a pop-up menu and to set the flag "Height relative to surface".

When manually creating a file of trajectory TX3, for example, obtained from external text file with coordinates, the file should have the following structure:

1) in the first line - a label of TX3 file and, through a space, type of coordinate system, in which source points are set (possible options: CS42, WGS84 - coordinates are set without height, CS423D, WGS843D - in coordinates the absolute height is set;

2) in the subsequent lines there are set through a space the points coordinates of a trajectory in the following order X (B) Y (L) H (optional coordinate, depending on specified type of coordinate system). Each point of a trajectory is written in a separate line.

Example of a file of trajectory 1:

TX3 WGS84

044.31762891 038.73583392

044.31761000 038.73582364

044.31774829 038.73610959

044.31789656 038.73641621

Example of a file of trajectory 2:

TX3 WGS843D

044.31762891 038.73583392 178.04

044.31761000 038.73582364 698.04

044.31774829 038.73610959 702.32

044.31789656 038.73641621 677.06

As a trajectory of objects movement there can be used the files of format NMEA received from GPS-devices.
