FAQ
DT1 to GIF Conversion
What are DT1 files?
DT1 is the file extension for Level 1 of Digital Terrain Elevation Data (DTED), a standardized elevation product described in the MIL-PRF-89020 specification of the U.S. National Geospatial-Intelligence Agency (NGA). Each file represents a one-degree by one-degree geographic cell and contains terrain heights sampled at a regular interval of 3 arc-seconds, equal to approximately 90 to 100 meters at the equator. Level 1 sits between the coarser Level 0 (.dt0) and the finer Level 2 (.dt2) products, and serves as a common choice for regional terrain analysis, flight planning, line-of-sight studies, and mapping at medium scales. The file starts with header records that identify the cell, its origin, and its accuracy, followed by the matrix of elevations. The format is a long-established standard in defense, aviation, and civil geospatial work.
What are GIF files?
GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
