Open HGT File

HGT files are a type of data file originated by the Shuttle Radar Topography Mission (SRTM). These digital elevation model (DEM) files contain gridded elevation data for the Earth�s land surface. Recognized for their direct application in geography and astronomy, HGT files offer an invaluable resource for 3D cartography and terrain visualization. This article shall explore the possible formats and ways to use HGT files, along with the applications that can open and manipulate these files.

Understanding HGT Files

HGT files are binary files which store data in rows and columns, each encompassing an area of 1 degree of latitude by 1 degree of longitude. The size and precision of data within a HGT file can vary. These can range from an extremely precise 1-arc-second resolution to the less precise, but more memory-efficient 3-arc-second resolution. The original source of these files is NASA's Shuttle Radar Topography Mission.

Applications for Opening HGT Files

There are various applications and software that can read and display HGT files. For instance, GDAL (Geospatial Data Abstraction Library), a powerful tool beloved by cartographers, can open and manipulate HGT files. This open-source translator library manages raster and vector geospatial data forms. The key strength of GDAL is its capacity to translate between a large number of file formats, including HGT.

Another useful tool is LP DAAC ASTER Global DEM Version 2. It is capable of converting HGT files into GeoTIFF files which can be used with conventional image editing software. This is a format that adds geographic information to the TIFF format, allowing the file to be georeferenced within the physical space.

GIS Software for HGT Files

Geographical Information System (GIS) software such as QGIS and ArcGIS can also open and process HGT files. These tools can create contour and color ramp visualizations of the elevation data, or even 3D visualizations. By utilising such software, users can fully engage with the data held within HGT files.

HGT File Important Information

It is important to note that although HGT files contain a wealth of topographical data, caution must be exercised when interpreting this information. While the data is generally accurate and of high resolution, it may still contain discrepancies in certain areas, which could impact its application in some use cases.

In conclusion, HGT files provide an extensive array of geographical and topographical data, valuable to a wide range of professions and applications. By understanding the various ways in which these files can be opened and manipulated with corresponding software, users can maximize the utility of HGT files to their specific needs.
