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 and opposite solar azimuth angles (east and west) were used to increase areal coverage. After map projection, the images were shifted in latitude and longitude to minimize offsets in regions of overlap, and the pixel values were scaled to reduce brightness contrasts caused by differences in illumination angles.

Due to the large size of this NAC ROI mosaic, the highest-resolution tiffs and pyramidal tiffs were down-sampled from 0.55 m/px to 0.80 m/px to fit the size constraints of the TIFF format.
