3		img2rr is a command line application used to create reduced resolution data sets for an image. These datasets are created by iteratively downsampling the full resolution image. The results are stored using a pyramid image structure called overviews. These overview files improve the efficiency of arbitrary access to different spatial resolutions and areas of interest. This is important if you want to zoom in and out of ossim applications like [wiki:OssimPlanet ~~OssimPlanet] or imagelinker~~ and are critical for rapid resizing using [wiki:orthoigen] and [wiki:igen].

5	5	Overview files created by img2rr use a ".ovr" extension. img2rr will also create a ".omd" file which contains basic radiometry information. Users also have the option to create histogram files when generating overviews. These files have a ".his" file extension.
