Union

Computes a Geometry representing the point-set which is contained in both Geometry columns. The union of two geometries of different dimension produces a result geometry of dimension equal to the maximum dimension of the input geometries. The result geometry may be a heterogenous GeometryCollection. If the result is empty, it is an atomic geometry with the dimension of the highest input dimension. Details are available here

Input Ports

: Table containing two geometry columns in GeoJSON format with other attributes. The geometry column name should be prefixed with "the_geom".

Output Ports

: Table containing a single geometry column after computing row-wise union of geometries. The geometry column name is prefixed with "the_geom".
