GeoTIFF - Georeferencing information to be embedded within a TIFF file.A compressed wavelet format, often lossy. ECW - Enhanced Compressed Wavelet (from ERDAS).
ECRG - National Geospatial-Intelligence Agency (NGA)’s Enhanced Compressed ARC Raster Graphics (Better resolution than CADRG and no colour loss). An SDTS format is used specifically for transferring raster data. SDTS - This format is used for transferring geographical information. GTOPO3O - Large complete Earth elevation model at 30 arc seconds, delivered in the USGS DEM format. 
Cell values in DEM represent the elevation for that position on the Earth’s surface. DEM is a raster format created by the USGS (US Geological Survey) for saving elevation data.
USGS DEM - The USGS’ Digital Elevation Model. Digital raster graphic (DRG) - digital scan of a paper USGS topographic map. Georeferencing and related metadata pieces of information are stored in one or more sidecar files. Binary file - An unformatted file consisting of raster data written in one of several data types, where multiple bands are stored in BSQ (band sequential), BIP (band interleaved by pixel) or BIL (band interleaved by line). ADRG - Arc Digitized Raster Graphic (ADRG) A general-purpose raster dataset for map displays on mission planning systems, Command and Control systems, and aircraft cockpits. Nevertheless, most GIS programs support other formats by having functions to import and export datasets. These file formats were created to optimize the efficiency of the program itself and were not designed to be used in other external programs. Nearly all GIS programs have their own file format. 
Each format has unique features and advantages: Shapefiles are widely used, Geodatabases support complex data structures, GeoJSON is compatible with web applications, and KML is used for Google Earth data. Below we have mentioned the List of Common GIS File Format used in GIS industry.Ĭommon GIS file formats include Shapefile (.shp), Geodatabase (.gdb), GeoJSON (.geojson), and Keyhole Markup Language (.kml). If you want to use GIS data that was saved in a particular format not supported by your GIS program, you must either find a way to transform the data or simply use another GIS program.

It is necessary to consider the file format of GIS data because software programs rarely support all file types. There are numerous formats available for both raster and vector data. Geographical features are often stored in Raster and in Vector format.
