WXtrackGL at work



This screen grab shows WXtrackGL at work.  I used the scroll bars to locate myself just to the north of the equator.  You can see the earth, with a relief map superimposed, and the tracks of a number of satellites.  The orbit of my primary satellite is shown as a red circle.  You can substitute your own surface image on the earth, making WXtrackGL capable of viewing a variety of information in a 3D format.

You can download WXtrackGL and use it free of charge.

Whether you want to work in real-time, or step ahead a month at a time is up to you.  Keep a constant viewpoint above your home location or anywhere on the earth, or fly along with the satellite.  The program's status bar maintains a continual display of time, viewpoint, and satellite position.

Another use for WXtrackGL is as a viewer of world information presented in a rectangular projection.  For example, here is combined thermal information from the world's geostationary satellites (produced by GeoSatSignal) showing white cloud areas superimposed on a shaded background map.

The composite rectangular image can be displayed in 3D and rotated to view as you wish.  In this case, the viewpoint has been set above Florida.
