Editing of semantics

To each map object some characteristics can be attributed. For example, it may be own name or height of object. All these characteristics are described in Semantics bookmark. For each characteristic the classifier of values can be created. Thus for numerical characteristics usually a range of values corresponds  to one code (for example, width of the river: up to 5м - 1, from 5 up to 10 - 2, etc.), for symbolical characteristics one value corresponds to one code (a building material: a tree - 1, a brick - 2, etc.).

If for the characteristic the classifier of values is created, this characteristic is declared as numerical one in the semantics table (physically its value is a numerical code, but at work with this characteristic in system of digital maps the logic value corresponding to the current code will be displayed). If the classifier of values for the described characteristic is not created it can be declared as numerical or character one. In this case physical and logic values of semantics coincide.

In Semantics bookmark at the left the list of classifier semantics is submitted as the table of 3 columns: a codea code, a key and semantics name. These fields cannot be edited.

Pressing one of columns in Sort by group it is possible to sort the semantics by code or by name.

In the bottom part of dialogue those objects are displayed for which chosen semantics is used. Objects for which semantics is obligatory are bordered by a yellow frame, for which semantics influences an image, are bordered  by blue frame.

Click twice on the necessary object for transition to the Objects bookmark.
