Geo Geometry Validation Filter


Description

Checks the geometry event if the geometry is simple and / or empty.


Required inputs

  • JTS Geometry
  • EPSG Code
  • Validation Type
  • Validation Output

Configuration

Validates geometry of different validations categories.

Point Geometry Field

Input Point Geometry

EPSG field

Integer value representing EPSG code

Validation Type

  • IsEmpty - Geometry is empty.
  • IsSimple - Geometry is simple. The SFS definition of simplicity follows the general rule that a Geometry is simple if it has no points of self-tangency, self-intersection or other anomalous points.
    • Valid polygon geometries are simple, since their rings must not self-intersect.
    • Linear rings have the same semantics.
    • Linear geometries are simple if they do not self-intersect at points other than boundary points.
    • Zero-dimensional geometries (points) are simple if they have no repeated points.
    • Empty Geometries are always simple!

Validation Output

Chose the output result of the filter.

  • Valid - all valid events are parsed through
  • Invalid - all invalid events are parsed through

Output

All events that match the validation output.
