The data consists of raster images and other graphics generated by scanning source documents. ADRG is geographically referenced using the equal arc-second raster chart/map (ARC) system in which the globe is divided into 18 latitudinal bands, or zones. For example: mission_l.dat (L-Band) and mission_c.dat (C-Band).ĭistributed on CD-ROM by the National Geospatial-Intelligence Agency (NGA). Multiple files with an L, C, or P in the file name followed by. ArcGIS supports the polarimetric AIRSAR data (POLSAR). FormatĪirborne Synthetic Aperture Radar (AIRSAR) PolarimetricĪIRSAR is an instrument designed and managed by NASA's Jet Propulsion Laboratory (JPL). For more information, see Displaying specific raster formats. It also lets you filter data at data-load time. You can specify which products you want ArcGIS to recognize ( Customize > ArcMap Options > Raster > File Formats) turning off products you don't use can improve performance. The following table gives a description of the supported raster formats (raster datasets) and their extensions and identifies if they are read-only or if they can also be written by ArcGIS. The geodatabase is the native data model in ArcGIS for storing geographic information, including raster datasets, mosaic datasets, and raster catalogs however, there are many file formats you can work with that are maintained outside a geodatabase. To determine if your data is supported as a raster product, raster dataset, or raster type, see List of raster dataset and type support. Each raster product applies enhancements, band combinations, and functions toĮnhance image's display according to settings within the software.Ī raster type is similar to a raster product, but is specifically designed to add data to the mosaic dataset. They are designed to help you display and use your imagery The metadata file that is used to generate them, such as satellite Will appear in the Catalog in place of the metadata filesĪssociated with specific vendor products as it's the information in Rows and columns, number of bands, actual pixel values, and other A raster dataset defines how pixels are stored, such as the number of
In ArcGIS, there are three ways to work with raster data: as a raster dataset, as a raster product, and as a raster type.
