Clauses

The following groups of clauses exist:

Specific polygons

Clause	As a polygon	As an item	Type
AREA	The requested data must intersect with this area.	It must be data of this area specifically.	ID indicating a specific area.
NEIGHBORHOOD	The requested data must intersect with this neighborhood.	It must be data of this neighborhood specifically.	ID indicating a specific neighborhood.
ZONE	The requested data must intersect with this zone.	It must be data of this zone specifically.	ID indicating a specific zone.
TERRAIN	The requested data must intersect with this terrain type.	It must be data of this type of terrain. There are no specific "instances" of terrain.	ID indicating a type of terrain.

Unspecific polygons

Clause	As a polygon	As an item	Type
AREA_WITH_ATTRIBUTE	The requested data must intersect with at least one area with this attribute.	N/A	Attribute name of one or more areas.
NEIGHBORHOOD_WITH_ATTRIBUTE	The requested data must intersect with at least one neighborhood with this attribute.	N/A	Attribute name of one or more neighborhoods.
ZONE_WITH_ATTRIBUTE	The requested data must intersect with at least one zone with this attribute.	N/A	Attribute name of one or more zones.
TERRAIN_WITH_ATTRIBUTE	The requested data must intersect with terrain with this attribute.	N/A	Attribute name of one or more terrains.

Grids

Clause	As a polygon	As an item	Type
MAXGRIDVALUE	It must have at least this value on a grid overlay.	N/A	Decimal number.
MINGRIDVALUE	It must have at most this value on a grid overlay.	N/A	Decimal number.
GRID	It must fall within this grid.	It must be data of this grid overlay specifically.	ID indicating a specific zone.
GRIDTYPE	It must fall within this type of grid.	It must be data of this type of grid, not a specific "instance" of this grid.	Technical name indicating a type of grid overlay.

Note that each grid automatically covers the entire map, unless a minimum gridvalue or maximum gridvalue is defined. For queries such as GRIDAVG, this can be acceptable. However, for example, a query of SELECT_LANDSIZE_WHERE_GRID_IS_2 is functionally the same as SELECT_LANDSIZE.

Also note that when a GRIDTYPE is selected but multiple overlays of that type exist in the project, there are no guarantees on which overlay is used specifically.
