GMapHD for Windows gives you a great moving map for your desktop flight simulator!
This is a versatile app, designed to run on Microsoft Windows (7 or later) but supports the most widely-used desktop simulators on the market (MSFS, P3D, FSX, FS2004, X-Plane or Aerofly FS 2) on multiple platforms.
It comes pre-packed with a huge collection of bonus Aero Charts and Nav Data (usable within GMapHD only) giving you a large map display to aid navigation, especially on VFR flights.
The map also features several weather data overlays including US Nexrad, world-wide Metar/TAF stations, cloud, rain, pressure and wind.
