[edit]

There were some misconceptions promulgated in the previous definition that I've clarified (or hope that I have) with some new verbiage:

  • The term geospatial PDF is too broad to be applied only a particular geospatial encoding. It's been used generically since at least 2002, and has been specifically used since 2008 to mean simply "PDF with any georeferencing payload".
  • There are two georeferencing techniques used today: an OGC best practice and Adobe's geospatial extension; a PDF file with either is rightfully considered a geospatial PDF as it's commonly used today.
  • Both techniques are open, published specifications. Neither is a standard with the imprimatur of a standards organization.
  • GeoPDF is not a format, it is a trademark used to brand geospatial PDF products created by TerraGo software.
  • GeoPDF uses geospatial PDF as a container; all GeoPDF is geospatial PDF, but not all geospatial PDF is GeoPDF. GeoPDF products can use either the OGC BP or Adobe's encoding -- encoding has nothing to do with "GeoPDFness".
  • Many of the features described in the original posting were not developed with geospatial in mind -- they are just PDF features that have convenient application in geospatial contexts.

Hope this helps!
