The new 4x4 Explorer App has 5 different map types. Is there more information on what these are?

Within the 4x4 Explorer there are five different map layers as follows:      

      • Premium Explorer Map - Hema’s complete topographic map with comprehensive on-road and off-road coverage plus complete Hema styling and attribution. This map has been built up over the last 30 years through Map Patrol field work. It's data is sourced directly from our mapping database that is used to create our printed maps (however incorporates all the latest updates). This is available as part of the app for online use. Offline use can be accessed via subscription ($49.99 per annum).                                                                                                                    4x4 Explorer App Map Hema Premium Map Style
