Re: SDW BP Glossary Issue 195: Spatial Thing

Chris,

I think your proposal is not what is intended. I do not know who added the link to the "spatial object" definition in ISO 19107, but a spatial object in ISO 19107 is not what we call a spatial thing. A spatial object is a geometry or a topology object. A spatial thing is a combination of the real-world phenomenon and its abstraction (the feature).

Best regards,
Clemens
