Aeronautical Maps

Our maps available for offline use, so that the app does not require any internet connection in flight. The maps are updated once per day, provided that new data is available. Note, however, that we do not guarantee regular updates.

The aeronautical maps are compiled from databases provided by the openAIP and the open flightmaps projects. While openAIP covers most of the world, the open flightmaps cover fewer countries but contain more detailed information.

List of maps

For simplicity, our maps are divided in “Class 1” and “Class 2”.

• Class 1 maps are compiled from openAIP and open flightmaps data. These maps contain complete information about airspaces, airfields and navaids. In addition, the maps contain (mandatory) reporting points. Some of our class 1 maps also show traffic circuits and flight procedures for control zones.

• Class 2 maps are compiled from openAIP data only. They contain complete information about airspaces, airfields and navaids.

Base Maps

Our base maps are generated from Open Streetmap data.

Terrain maps

Our terrain maps are derived from the Terrain Tiles Open Dataset on Amazon AWS. The underlying data sources are a mix of:

• 3DEP (formerly NED and NED Topobathy) in the United States, 10 meters outside of Alaska, 3 meter in select land and territorial water areas

• ArcticDEM strips of 5 meter mosaics across all of the land north of 60° latitude, including Alaska, Canada, Greenland, Iceland, Norway, Russia, and Sweden

• CDEM (Canadian Digital Elevation Model) in Canada, with variable spatial resolution (from 20-400 meters) depending on the latitude.

• data.gov.uk, 2 meters over most of the United Kingdom

• data.gv.at, 10 meters over Austria

• ETOPO1 for ocean bathymetry, 1 arc-minute resolution globally

• EUDEM in most of Europe at 30 meter resolution, including Albania, Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Kosovo, Latvia, Liechtenstein, Lithuania, Luxembourg, Macedonia, Malta, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, and United Kingdom

• Geoscience Australia’s DEM of Australia, 5 meters around coastal regions in South Australia, Victoria, and Northern Territory

• GMTED globally, coarser resolutions at 7.5”, 15”, and 30” in land areas

• INEGI’s continental relief in Mexico

• Kartverket’s Digital Terrain Model, 10 meters over Norway

• LINZ, 8 meters over New Zealand

• SRTM globally except high latitudes, 30 meters (90 meters nominal quality) in land areas
