When I use the Check Geometry tool in ArcGIS Pro, it asks whether I want to validate using ESRI or OGC methods. What is the difference between these two methods?

edit

I originally asked a second question in this post but it was too far off the first one.

Second question now here: Check for ESRI geometry validity using shapely or similar

  • @SonofaBeach fair enough. Opened a new question here: https://gis.stackexchange.com/questions/468669/check-for-esri-geometry-validity-using-shapely-or-similar – jesnes Oct 19 '23 at 01:07

According to the Check Geometry tool's help page...

The Esri validation option ensures that geometry is topologically correct using the Esri Simplify method. Only the Esri validation is available for data stored in an enterprise geodatabase.

The Open Geospatial Consortium (OGC) validation method ensures that geometry complies with the OGC specification as defined in OpenGIS Implementation Standard for Geographic information – simple feature access – Part 1: common architecture.

  • The banana polygon is what user meets most often https://postgis.net/workshops/postgis-intro/validity.html. And a single two-part hole that touches itself is the ESRI way https://desktop.arcgis.com/en/arcmap/latest/manage-data/using-sql-with-gdbs/geometry-validation.htm but an error for OGC. – user30184 Oct 19 '23 at 00:44
  • As a hole, that would be an inversion. It's inversions which are the difference, and plain vanilla inversions are way more common (especially in raster-to-vector conversions). – Vince Oct 19 '23 at 03:37
