Abstract
Some embodiments provide a non-transitory machine-readable medium that stores a program. The program receives an input specifying a location field of a dataset. In response to the input, the program further retrieves a set of geographical hierarchy definitions. The program also retrieves, from the data source specified for a level in the geographical hierarchy defined by a geographical hierarchy definition in the set of geographical hierarchy definitions, a subset of a set of geometries representing a set of geographical regions belonging to the level in the geographical hierarchy. For each geometry in the subset of the set of geometries, at least one record in the dataset has a spatial point in a location field that falls within the geometry. The program further provides the subset of the set of geometries in a view of a map.
