The two Narrow Angle Cameras (NACs) provide high-resolution (0.5 to 2.0 m/pixel) panchromatic images over a combined 5 km swath. Images acquired over many orbits and multiple months can be combined to create mosaics. NAC images acquired under similar lighting conditions (e.g. high sun/low sun) were map-projected using the GLD100 (WAC derived 100 m/pixel DTM) and LOLA derived crossover corrected ephemeris. In some cases images with similar incidence angles have opposite solar azimuth angles (east and west). A local semi-controlled network was then generated to align images into large mosaics of the region.

Due to the large size of this NAC ROI mosaic, the highest-resolution tiffs and pyramidal tiffs were down-sampled from 0.70 m/px to 0.82 m/px to fit the size constraints of the TIFF format.
