Open-file Reports and Maps
Several Geologic Maps are available in GeoPDF Format
Geopdfs are an electronic map product that have all the same features of regular pdfs but also have location information as part of the map attributes. Using the Avenza Maps App, geopdfs of topographic maps, geologic maps, and other maps in geopdf format can be viewed on the iphone, ipad, and Android devices.
For information about the Avenza application see: Iphone/Ipad Android Devices
The main advantage of using geopdfs on iphone, ipad, or an Android device is that you do not need a data connection to access the maps. All of the map data is on the device.
Important note for ipad and other tablet users, the basic model tablets may not have a built in GPS.
If you have any problems with the GeoPDF's, please email Michael.Medina@ncdenr.gov or pbradley@ncdenr.gov
