GEOSPATIAL PDF
A Geospatial PDF refers to a Portable Document Format (PDF) with certain geospatial encoding that relates a region on a PDF document page to a region in physical space. The establishment of this relationship is a process called georeferencing. The georeferencing metadata in the provided files uses the Adobe PDF 1.7 specification for writing geospatial PDF files.
The creation of Geospatial PDFs has enabled the 2011 Upper Mississippi River and 2013 Illinois Waterway Navigation Charts to be imported into location aware applications.
Avenza Systems’ free mobile application called PDF Maps allows users to download USACE chart files and view them on an iOS or Android device and received real time GPS locations. The Atchafalaya River, the Lower Missouri River, and the Upper Mississippi River Charts are currently available in the application store.
