GM_SpatialOps Methods

The OperationParams_t . GM_SpatialOps type exposes the following members.

Methods

	Name	Description
	DistanceInit	Initializes a GM_Distance_t struct members
	RunSpatialScript	Run a GM spatial script
	SpatialBuffer	Create a buffer
	SpatialCenter	Create a center point for each feature or collection of features
	SpatialCentroid	Create a center point for each feature or collection of features
	SpatialCircle	Create a circle around each feature or collection of features
	SpatialConcaveHull	Create a concave hull
	SpatialContains	Two-layer contains predicate
	SpatialConvexHull	Create a convex hull
	SpatialDifference	Two-layer difference operation
	SpatialDisjoint	Two-layer disjoint predicate
	SpatialDissolve	Single-layer dissolve operation
	SpatialEquals	Two-layer equals predicate
	SpatialIntersection	Two-layer intersection operation
	SpatialIntersects	Two-layer intersects predicate
	SpatialMBR	Create an MBR for each feature or collection of features
	SpatialOperation	General spatial operation
	SpatialOpsParameterInit	Initializes a GM_SpatialOps_Params_t struct members to their default values
	SpatialOverlaps	Two-layer overlaps predicate
	SpatialPredicate	General predicate function
	SpatialRelate	Two-layer relate predicate. This function is a general purpose predicate that implements the DE-9IM standard for specifying spatial predicates beyond the common 'named' predicates like 'equals', within', etc. See https://en.wikipedia.org/wiki/DE-9IM for more information. The aStr parameter must be a 9 character string containing 'T', 'F', or '*' characters as discussed in the Wikipedia article, denoting the desired spatial predicate.
	SpatialSymmetricDifference	Two-layer intersection operation
	SpatialTouches	Two-layer touches predicate
	SpatialTransform	Spatial transform types
	SpatialUnion	Two-layer union operation
	SpatialUnionSingle	Single-layer union operation
	SpatialWithin	Two-layer within predicate
	SpatialCrosses	Two-layer crosses predicate
	SpatialCovers	Two-layer covers predicate
	SpatialCoveredBy	Two-layer covered-by predicate
