Available map layers:

• Topo maps 1:50.000 and 1:250.000 with seamless coverage for Guatemala, Honduras, El Salvador and Nicaragua. Belize, Costa Rica and Panama are covered with 1:250.000 topo maps.

• Google Maps (Satellite images, Road- and Terrain-Map)

• Bing Maps (Satellite images, Road-Map)

• Open Street Maps (OSM Mapnik and Cloudemade Cyclemap)

• Hillshading overlay layer for OSM, Google or Bing maps

On the 1:50.000 maps you'll find many small roads, pathes and 4WD tracks that are not included in Google, Bing or OpenStreetMaps. The topo maps have a very detailed topography with contour lines. There is no other online mapping service/app available that gives you more detailed geographic features like rivers, lakes, hills, vegetation, villages, etc. for this region.

The topo maps layer is a seamless mosaic of more than 1000 georeferenced maps. Although some of the maps are quite old (production range of the maps is 1955 - 2006) they are still very good for outdoor trips, especially if you are looking adventurous routes or abandoned places. Most maps of Guatemala are quite up to date (mostly created in the 90ies) while maps of eastern Nicaragua were created in the 60ies/79ies. Within the app you can open an overview map with the publishing dates of the maps.

In larger cities you'll find it more usefull to switch to Google or OSM maps but in the backcountry you will recognize the relevance of large scale topographic maps.

The 1:250.000 maps are JOGs (Joint Operations Graphic) which represent a medium scale map intended as both a topographic and an aeronautical chart.

Use this navigation app for outdoor activities like hiking, biking, camping, climbing, riding, canoeing or offroad 4WD tours.

Preload FREE map data for areas without cell service.

The topographic maps are enhanced with Atlogis® hillshading and placenames.
