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. However, GeoPDF products conform to published specifications including both the OGC best practice for PDF georegistration as well as Adobe's proposed geospatial extensions to ISO 32000, making them readable by applications such as Adobe Acrobat, Adobe Reader, Avenza PDF Maps, Global Mapper, and others. GeoPDF products often include other advanced PDF features such as layers and object data which can add significant GIS functionality to the file, particularly when used with the TerraGo Technologies plugin to Adobe Reader or other TerraGo clients.

Naming
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.
