2. Selection Guide

Country :

Depending on the flight you may have to select one or more of the countries or regions

Date : TherMap provides maps of selected dates from the beginning of April to the middle of September (Months 4 to 9). Select the maps showing the date closest to the flight date.
The map date/time is included in its file name (month-day-hrZ)
Time:
UTC is now generally used, wherby 3 map times per day have been included in the map collection, namely one for the latest full hour before the highest elevation of the sun, and two others 3 and 6 hours later, respectively. If we tolerate that the map-time may differ up to 90 minutes from the flight, these three maps basically cover a total time interval of up to 9 hours.

UTC is normally also used in the flight records. Select the map closest to the time of overflight. A longer flight will therefore require several maps. This also applies to flight analyses, for which we recommend however to make use of the Google Earth overlays of TherMap.

3. Map Download Menu (old version)

Note that the following menu contains the old download maps of TherMap1.6 (100% coulour coded), whereas the more advanced TherMap2 maps cover also US regions and show surface areas with low thermal potential as topographic backdrops, to make the maps more readable.

Each OK fields of the following table represent a map of a region at a given date and time. Select the one closest to your flight path. (about 6-10 Mb per JPG map). Then either

  • double click on the field of the map to be viewed (about 6-10 Mb per JPG file),
  • or right click on the target field and request the map to be saved directly in a directory of your PC.

The complementary maps either show the basic topography or the slope determined view of the region.
