System Table TB_INTERSECTION

The following table stores intersection definitions.

Note: The properties are set with the data model administrator.

Attributes of TB_INTERSECTION

Description

ID

Stores the unique key, which is system-generated.

NAME

Specifies the name of the intersection.

TYPE

OO = Polygon/Polygon => Polygon

OL = Polygon/Line => Line

OP = Polygon/Point => Point

LL = Line/Line => Point

LP = Line/Point => Point

ADJUST_SECOND

True/false: Adjusts the area of the second feature class to the area of the first feature class. Only useful for polygon/polygon intersections.

ADJUST_EXCLUDE

Specifies the condition that excludes features from an adjustment. Example: s.area <100.

BUFFER_PRIM_FC

Defines a perimeter for a buffer. All features inside the perimeter are returned.

F_CF_CLASS_NAME_PRIM

Primary feature class.

F_CLASS_NAME_SEC

Secondary feature class.

F_CLASS_NAME_INTER

Specifies the name for intersection feature class. If the table does not exist, it is created automatically. The name must not contain blanks.

PRIM_JOBID

SEC_JOBID

Specifies the job used to get data from DB. If “JOBID= 0”, the currently selected job is used.

PRIM_UPDATE_STATEMENT

SEC_UPDATE_STATEMENT

Selects values from other tables to store in the intersection feature class. These values can be used for reports. This method is faster than creating a view that joins information from other tables and from the intersection results.

STORE_GEOMETRY

Stores “AREA” and “AREA_NOMINAL” on OO intersections (polygon/polygon). Set to true or false.

TOL_AREA_NOMINAL

Stores the maximum value of the difference between the area of the primary and summary of the secondary feature class where no adjustment is started.

TOLERANCE

Sets the spatial tolerance for the intersection. This tolerance is equal to the smallest tolerance of primary and secondary feature class.

WHERE_CLAUSE_SEC

WHERE_CLAUSE_PRIM

Restricts features participating in the intersection. The restriction can be defined as a WHERE Clause.

TB_STATE_INTERSECTION defines the state in which the intersection applies. If an intersection is called with the same primary and secondary feature classes, it must be executed before the merge job. All other intersections can be called after the merge.
