Change of object type

This mode is used for recoding map objects. The task is performed in group mode (for pre-selected objects) or in single mode (for an object selected on the map). If objects were selected on the map before the mode starts, the user is offered the option to perform group recoding of those objects or to switch to single mode. In this case, a check is performed to ensure that all selected objects belong to the same map. If objects from different maps are selected, recoding is not performed.

If objects with different localizations are selected on the map, a warning and a request to continue processing are displayed.

The new object type is selected from the classifier. If the localization of the source objects differs from the localization of the new object type, then when recoding to a point object, the user is prompted to choose a metric conversion type:

• take the coordinates of the first point of the metric;

• calculate the coordinates of the geometric center of the object;

• calculate the average position of the coordinates of the object's points;

• form a multipoint object;

• form an array of point objects.

When recoding area objects to a vector object, the user is prompted to choose a metric conversion type:

• calculate the metric from the geometric center of the object;

• form the metric from the metric of the longest edge of the area object (useful, for example, when recoding buildings).

If during processing it is detected that the semantics of the object being recoded are invalid for the new object type, a request is made to delete the invalid semantics.

In turn, single mode can be performed either by selecting a new type for each object selected on the map or by “fixing” a new type. In this case, an object is selected on the map as the type reference, and objects subsequently selected on the map will be recoded to the new fixed type.

Switching the method for selecting the new object type, the metric conversion methods, as well as the procedure for handling invalid semantics in single processing mode are switched on the auxiliary panel of the mode.
