Geographic Coordinates

Using gdal library, I have reached the geographical coordinates of the dted file we have.
Results are:

Corner Coordinates:
Upper Left  (  29.9998611,  38.0001389) ( 29d59'59.50"E, 38d 0'0.50"N)
Lower Left  (  29.9998611,  36.9998611) ( 29d59'59.50"E, 36d59'59.50"N)
Upper Right (  31.0001389,  38.0001389) ( 31d 0'0.50"E, 38d 0'0.50"N)
Lower Right (  31.0001389,  36.9998611) ( 31d 0'0.50"E, 36d59'59.50"N)
Center      (  30.5000000,  37.5000000) ( 30d30'0.00"E, 37d30'0.00"N)

If we find texture of that area, we shall use it to improve visualization.

PS: The unit that is used to indicate elevations is in meters (m).
