A trademark branded instance of geospatial PDF. Use this tag ONLY for TerraGo software produced pdfs.
Geospatial PDF is a set of geospatial extensions to the Portable Document Format (PDF) that relate a region in the document page to a region in physical space.
GeoPDF refers to map and imagery products created by TerraGo software applications. GeoPDF products use geospatial PDF as a container for maps, imagery, and other data used to deliver an enhanced user experience in TerraGo applications.
The GeoPDF trademark should not be confused with georeferencing techniques such as the OGC best practice or Adobe's geospatial extensions to ISO 32000 or with geospatial PDF files in general. Nothing about the georeferencing metadata in a GeoPDF product is proprietary; these metadata are embedded in conformance with published specifications and best practices. GeoPDF is best thought of as a branded instance of geospatial PDF.
