Settings to be used in file checking. The checking is done either by separate check function or automatically always before triangulation. Settings are given separately in each case.
In the file check before triangulation same settings are forced to constant values. Arcs are newer allowed in triangulation and checks are made for all surfaces and feature codes. Same points are allowed, because they have no effect on terrain model structure.
Searches codes and surfaces not found in the code file. Empty surfaces or all surfaces can be allowed by separate settings.
If separate control file is given, correct point/line coding and surface/code matching are checked according to it. If the control file is not given or it is asterisk (*), same information is searched from the current code file code definitions. Surface check skips six number infra-surfaces.
Control file defines one code on each line and uses following format: code type surfaces description. Code can contain wildcards * and ?. Type contains character P for points and/or V for lines. Surfaces contains comma separated list of allowed surface codes. Description is optional.
Example:
10 P 1,2 Korkeuskiintopiste 11 P 1,2 Korkeustukipiste 12 P 1,2 Apupiste 20 V 1,2 Apuviiva 83 P 9 Kiskokosketin 88 P 9 Vaihteenkosketin 89 P 9 Varmistuslukko 120 V 1 Tien reuna 121 V 1 Tien keskilinja
Compares all points and lines regardless their surface code. By default only same surface points are compared.
Checks also surface 9 points.
Allows undefined or zero heights.
Allows arcs in the file. Arcs are not allowed in the check made before triangulation.
Searches equal lines and line sections. If whole lines are identical, only one error is generated. Otherwise separate error is generated from each identical line section. Line point horizontal distance is must be less than point-point distance and height difference less than height difference setting.
Allows points with exactly same coordinates. These kind of points cause no problems in terrain model generation.
Allowed minimum and maximum length for line sections. Check is made only if the maximum is greater than the minimum.
Allowed minimum and maximum height for points. Check is made only if the maximum is greater than the minimum.
Horizontal comparison distance between points.
Horizontal comparison distance between point and line.
Allowed height difference in comparison.
Comma separated list of codes skipped in the distance check. The check is skipped only if both compared objects have code that is found from the list. The setting is usable, for example, with curbs. Codes cannot be skipped in the check made before triangulation.
Copies settings from the file checking or triangulation depending on current location.
Reads or writes settings to file.
There are some special settings related to this function.
1 No crossing lines check. Skips crossing breaklines checking.
2 No code file checks. Skips all code file checks.
