Control of presence of the common points on a vector map

This task is intended for control of presence of the common points of objects of a vector map.

The list of controllable objects is set by the filter installed into open maps.

Before starting of the program onto execution (Run button) the operator can choose checked objects. For this purpose it is necessary to press Filter button and in Choice of checked objects dialogue to choose objects which will be checked (Objects of the first group) and objects with which the control of presence of the common points (Objects of the second group) will be carried out. If the operator did not choose checked objects the control of presence of the common points will be carried out over all objects of a vector map.

Results of work of the program will be rendered on the created user map as multi-colored points. The name of the user map can be chosen by operator. By default the name of the user map coincides with a name of a vector map.

The analysis of work of the program consists in the analysis of color of points on the user map and calculation of quantity of common points in the given point for the chosen checked objects of a vector map. If color of a point does not coincide, it means a mistake in the metric description of a vector map in the given point. As at least two objects have the common point, the number of the common points is determined by quantity of the objects containing a concrete point.

Conformity of color and quantity of crossing points is submitted in the table.

№        Quantity of the common points          Color        

1        1                                              Black        

2        2                                              Violet        

3        3                                              Darkly green        

4        4                                              КBrown        

5        5                                              Grey        

6        6                                              Fuchsia        

7        7                                              Yellow        

8        8                                              Blue        

9        9                                                White        

The program counts up no more than 9 common points in a concrete point of a vector map. If quantity of the common points in the given point more than 9 it will be displayed by white color.
