DTED driver doesn't honour "Longitude count" field of Data Record
|Reported by:||Even Rouault||Owned by:||Even Rouault|
There are files in the wild that declare for example 3601x3601 cells. But they don't contain all the 3601 columns that are normally expected. They for example have just [colA, colB] columns. This situation can be detected by checking the value of the "Longitude count" field (at byte 4) of each data record. The columns that are not physically present in the files should be filled with nodata value.
