T3D3 and GTOPO30 DATA

Ready to use GTOPO30 data for TD2D are available for download here

Africa East Area , 8MB, for Bulwer, The Dam, Barberton,...
Africa West Area, 3MB, for Porterville, Cape Town ,...
Europe Area 8MB

Create a new directory
Unzip the files under the new directory.

for example create a directory structure ... C:/T3D2/DATA/GTOPO30/E020S10 with 3 files in it

a HDR header file
a JPG picture file used as background for the scan window user interface
and the DEM file with the grid data

For other GTOP30 data use http://edcdaac.usgs.gov/gtopo30/gtopo30.html
get another area file
and on a UNIX box

gzip -d the file

tar -xvf the file

T3D2 needs the DEM and JPG file in binary and the HDR as ascii text file
in a Directory which gets defined to T3D2 using the Configuration button

How to do a scan and create a new Site inT3D2

In the code choose a GTOPO30 directory . Like E020S10

Enter the Center coordinates of your flying site Or the start coordinates of your flight In decimal degrees. Like -31.1234 South is negative. West is negative

Define the amount of strips to each side
A GTOPO30 Strip is about 1km
10 = means 10km to the North and 10km to the South of it

and the same applies for East West

give the new site a name
Press GO scan
A directory with that name gets created under the sites directory
The code shows some output as it tries to find the site inside the GTOPO30 data.

Once done, exit, close down the program. Restart and now you should fin the new created site i the site selection multichoice. Select the new site

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 about this track log is.
It then cuts out of the DEM data the area that you are flying over. Then displays it as a site called Auto or whatever you define it in the Config options.
