Operations between Geometries

KNIME Spatial Processing Nodes version 1.2.2.v201911131528 by EIFER (European Institute for Energy Research)

Takes two tables containing geometries in WKT format. These two tables should have the same count of entities. Line by line the operation will be applied and the result will replace the geometry of the first table.
  • difference: the parts of the first geometry minus the second one
  • intersection: the parts common to the first and second geometries
  • union: the union of both geometries

The actual computation is done by the Geotools library.
