Disjoint node

​

Description​

The Disjoint node takes two geographic inputs. It filters the items in your query by checking if the first area falls completely outside the second area.

Usage​

The Disjoint node is a condition, so it can be added to the query branch directly after the root node or a logical node.

It can be populated with these nodes:

Configuration​

alt text

  • ​ Swap - change the comparison node. If any segments hold values, they'll remain but the node types offered will be limited.

  • ​ Delete - remove the node from the query.

  • Link negated - enable this to invert the condition imposed by the node. Items must now fail the condition to be included in the query results.

Note

If you enable Link negated when comparing an Attribute node, the query will also fetch items where the attribute holds no value at all. If this isn't desirable, use the Within node instead!

Example​

Fetch all inspections outside of this area

In full detail:

Fetch items of the Inspections interface where their Geometry attribute falls completely outside the defined area
