Interface  Description 

BBOX 
Spatial operator that evaluates to
true when the bounding
box of the feature's geometry overlaps the bounding box provided in this object's properties. 
BBOX3D 
An extension to the general BBOX filter for supporting 3D Bounding Boxes that have a minimum and maximum Zvalue.

Beyond 
Concrete distance buffer operator that evaluates as
true when all of a feature's geometry lies beyond (i.e. is more distant) than
the given distance from this object's geometry. 
BinarySpatialOperator 
Abstract superclass for filter operators that perform some sort of spatial
comparison on two geometric objects.

BoundedSpatialOperator 
Marker interface for spatial operators that are a subset of the BBOX relationship.

Contains 
Concrete binary spatial operator that evaluates to
true if the the first geometric operand contains the second. 
Crosses 
Concrete binary spatial operator that evaluates to
true if the first geometric operand crosses the second (in the sense defined
by the OGC Simple Features specification). 
Disjoint 
Concrete binary spatial operator that evaluates to
true if the first operand is disjoint from the second (in the sense defined
in the OGC Simple Features specification). 
DistanceBufferOperator 
Abstract superclass for spatial operators that check that one shape satisfies
some relation to a buffer around another shape.

DWithin 
Concrete distance buffer operator that evaluates as
true when any part of the first geometry lies within the given distance
of the second geometry.

Equals 
Concrete binary spatial operator that evaluates to
true if the geometry of the two operands are equal. 
Intersects 
Concrete binary spatial operator that evaluates to
true if the two geometric operands intersect. 
Overlaps 
Concrete binary spatial operator that evaluates to
true if the interior of the first geometry somewhere overlaps the
interior of the second geometry. 
SpatialOperator 
Abstract base class for operators that perform a spatial comparison on
geometric attributes of a feature.

Touches 
Concrete binary spatial operator that evaluates to
true if the feature's geometry touches, but does not overlap with the
geometry held by this object. 
Within 
Concrete binary spatial operator that evaluates to
true if the feature's geometry is completely contained by the constant
geometry held by this object. 
true
if the spatial relationship is satisfied. Otherwise the operator evaluates to false
.
The following is adapted from
Filter encoding implementation:
Spatial operators
are used to test whether the value of a geometric property, potentially referenced using the name of the
property, and a (potentially literal) geometric value satisfy the spatial relationship implied by the operator.
For example, the Overlaps
operator evaluates whether the
value of the specified geometric property and the specified literal geometric value spatially
overlap.
The BBOX
element is defined as a convenient
and more compact way of encoding the very common bounding box constraint based on the gml:Box
geometry. The BBOX
operator should identify all geometries that spatially interact with the box
in some manner.
The spatial operators DWithin
and
Beyond
test whether the value of a geometric property is
within or beyond a specified distance of the specified literal geometric value. Distance values
are expressed using the distance
attribute. The content of the distance attribute represents the magnitude of the distance and the
units attribute
is used to specify the units of measure.
