Outputs
Result table [Table]
Spatial Match
Description
This component establishes the spatial relationship (contains, intersects, touches, etc.) between two sets of spatial objects. The component accepts a set of spatial objects from the Target Input and a set of spatial objects from the Universe Input. At least one input stream should contain Polygon type spatial objects.
Inputs
Targets [Table]Universe [Table]Target Spatial Object Field [Column]Universe Spatial Object Field [Column]Type of Spatial Match [Selection]Output Intersection Object (Intersects Only) [Boolean]
Outputs
Result table [Table]
ST Difference
Description
This component creates a new table containing the difference between the geographies of the input table and the combined boundary of the geographies in another table. That is, the part of the original geography that doesn't fall within the boundary of the ancillary table.
Geographies in the secondary table must be of type polygon.
Inputs
Source table [Table]Polygons table [Table]Geo column in source table [Column]Geo column in polygons table [Column]
Outputs
Result table [Table]
External links
ST Intersection
Description
This component creates a new table containing the intersection between the geographies of the input table and the geographies in another table.
Columns from both tables are copied to the output one, and a new one with the intersection is added.
Inputs
Source table [Table]Polygons table [Table]Geo column in source table [Column]Geo column in secondary table [Column]
Outputs
Result table [Table]
