FeaturesData Types and Integration Image Analysis for ArcGIS is tightly integrated with ArcGIS and can run on ArcView, ArcEditor or ArcInfo. ESRI’s ArcGIS allows direct access to many raster data formats. Image Analysis forArcGISallowsforthecreationofaTIFF,ESRIGRIDorERDASIMAGINE®.imgfileafter processing. Image Analysis for ArcGIS also supports the import and export of numerous satelliteandimagefileformats.

Image Processing and Analysis Image Analysis for ArcGIS provides access to a number of tools that are useful in general image preparation as well as several standard image processing and GIS techniques that will enhance andanalyzedata.Forexample,ausercansubsetanimagetocreateanewimagethatcontainsjust one particular area of interest, or mosaic a number of images and make use of the software’s color balancing options.
