Setting the appearance of the object

The appearance of the object on the map is determined by the conventional sign assigned to this object. Conditional signs are contained in the digital classifier of a vector map.

The assignment of a symbol to visualize the database object on the map during the import and export operations of the layers DTM from DB Oracle is performed on the base of correspondence the value in the field MADOITUONG of each table with spatial data from the geo database ArcSDE and the alphanumeric code of the object in the digital map classifier.

Under one value of the alphanumeric code of an object in a digital classifier of a map there can be several conventional signs.

When you select a conditional object by the value of the alphanumeric code, the nature of its localization is taken into account. Localization is a kind of spatial object: area, linear, point.

In addition, under a single value of the alphanumeric code of the object in the digital classifier, there can be a whole series of objects. In this case, when the final choice of a conventional sign is made, its semantic characteristics affecting the species are also taken into account for its mapping onto the map.
