The Visual Imaging Subsystem Cameras A and B (VISAB) High Resolution Mosaicked Digital Image Models (MDIMHs) are a cartographic extension of the Experiment Data Records (EDRs). They contain cartographic compilations made by processing the raw images to reduce radiometric and geometric distortions to form geodetically controlled images.
There are 8 volumes of MDIMHs. Each of the volumes contains MDIMHs of the areas specified at 1/1024 deg/pixel (58 meter/pixel) resolution. For this high resolution data set, each MDIM 1:500,000 quad for which high resolution coverage was available has been divided into sixteen tiles, each approximately 1.25 x 1.25 degrees squared.
The contents of the 8 volumes are below (with links to the volume).
