Questions & Answers
DT2 files: Frequently Asked Questions
What are DT2 files?
DT2 (DTED Level 2 Elevation Raster) is the finest standard level of the DTED family, with one-degree cells sampled every 1 arc-second, producing a 3601 by 3601 grid of about 13 million samples and a file of roughly 26 megabytes in low-latitude zones. The structure repeats that of the lower levels: an 80-byte UHL header, a 648-byte DSI record, a 2700-byte ACC record, and one data record per longitude line, each opened by the 0xAA sentinel and closed by a checksum. The longitude spacing widens in five latitude zones, from 1 to 6 arc-seconds, so cells near the poles hold far fewer columns. Elevations are stored as big-endian 16-bit sign-magnitude integers, and -32767 marks voids, which are common over water and steep terrain. Because of the size, graphics conversion benefits from tiling or downsampling, and mosaicking adjacent cells requires matching their edges, since neighboring files share boundary rows and columns. After decoding, the grid is rotated into image order and rendered as a 16-bit grayscale heightmap, a color-ramped relief, or a hillshade in PNG, JPEG, or TIFF, while GeoTIFF preserves the exact elevations. Supported by Global Mapper, QGIS, ArcGIS, Surfer, and Blue Marble Geographic Calculator.
