Semantics

On the Semantics tab, you can select objects based on a combination of conditions applied to the values of their semantic characteristics. For example, to select objects whose absolute height value is greater than 100 meters, you need to form an expression like: absolute height > 100.

Groups: All — the object will be found only if it contains all of the specified semantics and their values in the group at the same time.

Groups: At least one — the object will be found if at least one of the specified semantics or its value in the group matches.

Add	Adds a condition based on a semantic value. The selected semantic is added to the current group condition. Multiple selection of semantic characteristics is available.
Add Group	Adds a group condition for semantics
Delete	Deletes the selected semantic condition or group condition
Copy	Copies the selected semantic condition or group condition
Undo	Restores the original semantic conditions
Reset	Resets all semantic conditions
Set General Condition	Sets a general condition for semantic groups: "All (AND)" – All group conditions are considered. "At Least One (OR)" – At least one group condition is considered.

Edit Group Condition

!=	The semantic characteristic value is not equal to the specified one
*	Any value for this characteristic is allowed
<	The semantic characteristic value is less than the specified one
<=	The semantic characteristic value is less than or equal to the specified one
=	The semantic characteristic value is equal to the specified one
>	The semantic characteristic value is greater than the specified one
>=	The semantic characteristic value is greater than or equal to the specified one
х	Any value for this characteristic is forbidden
~	Partial match. For each line in the list, the search for a partial match is performed for every substring separated by a space, period, comma, semicolon, or tab. If a substring contains only digits, the same substring is searched for without other digits at its edges (for the substring "21", the substring "121" or "213" will not be found, but "21.0" is acceptable). This allows, for example, finding an address by the first letters of the street name and the exact house number. For example, for the string "Nog Rog 117", objects with the semantics "Noginsk, ul. Rogozhskaya d.117", "Noginsk Rogozhskaya 117", and similar will be found.

Edit Value

Double-click the left mouse button in the "Value" field. Activates the field for entering values.

For a semantic with a value selected from a classifier, a list is generated. The first value from this list is set by default.

For a quick search, enter a value, and the list will be filtered by any case-insensitive partial substring match.

Drag&Drop Mechanism

Dragging one or several semantic conditions is done by selecting the required conditions from different group conditions in the "Group Condition" field.
