USGS Semi-Controlled Mosaics


Availability: Data Accessible Elsewhere


This data set consists of 30 quadrangles of semi-controlled paper photomosaic maps of the Martian surface, ordered by quadrangle map number, e.g., MC-1. Each quadrangle on 76- x 91cm [30-x 36-in.] paper) consists of (1) the photomosaic map, and (2) the individual, unrectified B-camera (high resolution) frames that comprise the map. The individual frames are on a 110-x 15-cm (4-x 6-in.) format and are identified by DAS number. The mosaic maps are made with computer-enhanced photos, rectified and scaled to polar stereographic projection near the poles, Lambert conformal projection for midlatitudes, and Mercator projection for low latitudes. Descriptions of methods used are included on each map. The location and scale of each quadrangle with respect to the Martian surface are indicated in an insert map.
