What is a .DT1 file?
The file extension .DT1 refers to a DTED Level 1 File, which stands for Digital Terrain Elevation Data. This type of file is primarily used in military Geographic Information Systems (GIS) to display detailed terrain elevation data. The data inside a .DT1 file is organized as a grid of elevation points that are evenly spaced apart. This grid helps in providing essential information about the terrain's elevation, slope, and surface contours, which are crucial for military planning and operations.
DTED files come in three levels of detail: Level 0 (.DT0), Level 1 (.DT1), and Level 2 (.DT2). Among these, Level 0 files have the coarsest detail, providing the least precise elevation data, while Level 2 files offer the most detailed and precise elevation data. The Level 1 files, such as the .DT1, strike a balance with a resolution of three arc seconds, which translates to about 100 meters. This makes them detailed enough for many applications while not being as large as Level 2 files.
To open a .DT1 file, you can use various specialized software programs that are capable of handling GIS data. Some of the most commonly used programs include: 1. **ESRI ArcGIS Desktop** - A popular GIS application used for creating and managing geographic data. 2. **Safe Software FME Desktop** - A versatile tool that allows for the conversion and integration of GIS data. 3. **Pitney Bowes MapInfo** - Another GIS platform that provides tools for mapping and spatial analysis. 4. **Blue Marble Geographics Global Mapper** - Known for its extensive support of different data formats and GIS capabilities. 5. **TatukGIS Viewer** - A free GIS viewer that supports a wide range of data formats including DTED files.
These programs enable users to view, analyze, and manipulate the terrain data contained in .DT1 files, making them valuable tools in military and other geographic applications.
