Charts Download - GeoPDF Format

All 107 IENCs have been produced in the GeoPDF product format. The GeoPDF product opens in the widely available Adobe Acrobat Reader software and allows those users without formal Electronic Chart Systems or Geographic Information System software access to the IENC product and many additional geospatial tools. The GeoPDF format was designed by TerraGO Tech, and provides the chart user with many add-on tools when their free TerraGO Toolbar (hyper link, please, to TerraGO Toolbar text) is installed on the user's machine. In addition, professional GIS users can pass IENCs in the GeoPDF format to other GIS users for ingestion using embedded, vector-specific GeoPackage technology.

A software 'plug-in' is required in order to enable all functions of the GeoPDF product within Adobe Acrobat Reader. Please visit the TerraGO page for Free TerraGO Toolbar to download and intstall the 'plug-in'.
