Using GLOBE data to create a new Site


GLOBE data is located at
 

http://www.ngdc.noaa.gov/seg/topo/globedoc.shtml

for South Africa use

http://www.ngdc.noaa.gov/seg/topo/report/s10/s10.html

One can get it via ftp
 

FTP: ftp.ngdc.noaa.gov
USERID: anonymous
PASSWORD: [your email address]
: dir
: cd GLOBE_DEM/data/elev
: binary
: get [filename] or mget [filespecpattern]
: bye

For Java one has to do a byte swap

dd if=inputfilename of=outputfilename conv=swab


Create a directory for the GLOBE data.
In my setup I use C:/T3D2/DATA/GLOBE/ and a new directory that I called AFRICA or EUROPE or whatever area your GLOBE file represents
For example create a C:/T3D2/DATA/GLOBE/AFRICA directory.
Into the AFRICA directory put the GLOBE file and call it AFRICA.DEM .
It has to be the same name as the directory.
Also put a screen grab from the area as AFRICA.gif

In the T3D2 code choose from the GLOBE data your area,
type in the center coordinates of your flying site
the amount of strips , ( 1 strip is rougly 1km) towards each side
and give it a name

One can also reuse a previously defined site and modify the values and save it under a new name


AutoView

One has to choose a DEM data area, like Africa
Click on the AutoView button, select an IGC track log, and the code determines where this track log is located.
And the code then cuts out of the DEM data the area that you are flying over. And tThen displays it as a site called Auto.
