Restrictions on the composition of fields and their type

In the cartographic view, the user can only be represented with that composition of the fields of the initial table of the spatial database, which is defined in the DBM file in the form of the correspondence between the fields of the table and the semantic characteristics of the map objects. Editing the semantic characteristics of objects is also available only in this volume.

There can be restrictions in work with fields of specific types of data which does not have an equivalent in the map classifier. Correct work is guaranteed only with numerical and string fields.
