Point location queries also retrieve the polygon that includes the point.
Object Data Queries
Any topology object can be queried using object data, such as node, link, and
polygon identifiers; the "from" and "to" node information on links; the left
and right side information on links; polygons; and so on.
Topology queries can retrieve data such as areas, perimeters, numbers of links,
and more. For example, a query to retrieve objects with an area greater than
a specified value gives different results with the two query types:
A query defined with a standard Define Query Of Attached Drawings
retrieves closed polylines with areas of the specified value.
A Define Topology Query retrieves all polygons with areas of the specified
value, whatever the objects making up the polygon (lines, arcs, or open
polylines) are.
