Geospatial PDF Viewer

ArcGIS Explorer App | Avenza (Geospatial PDF) App

"Mobile Apps" are native applications, applications that are downloaded and installed on a mobile device. The ESRI ArcGIS Explorer App provides interactive map functionality and requires cell service to work properly in the field. Geospatial PDF apps such as Avenza do not require cell service to work in the field if maps are downloaded prior to entering an area with spotty or no cell service.

Both will work with a smartphone's GPS to locate the phone's current position on a map.

SUPPORT: The North Dakota Game and Fish Department is unable to provide support for problems that may be encountered when installing and using the Avenza Maps Mobile App software. Please see the Avenza support website for software information and installation help.

Geospatial PDFs

Geospatial PDF maps can be very useful when hunting, fishing or hiking in North Dakota where many areas do not have good cell reception. These maps can be downloaded and saved on a smartphone prior to going into the field. Once in the field, the phone’s GPS can be used to display the user’s current location on the map. No cell service is required since the map is already stored on the phone.

To use a geospatial PDF on a smartphone a specialized application like Avenza Maps Mobile App must be installed. Avenza Maps Mobile App is currently free (though the free version limits the number of maps that can be loaded to 3 at any one time) and can be downloaded from both the Apple and Android stores. See below for more information.

Using the Avenza Maps Mobile App

After installing the Avenza application, maps can be added in a few different ways. The example below shows how to load a map from a URL on an iPhone. This process will look somewhat different on an Android.

Note: Many of our maps are available for free from the Avenza store as well. To find them search 'ndgf'.
