USGS Photomosaics 7.5M

NSSDCA ID: PSPA-00325

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Description

This data set consists of B/W 8 x 10 in. negatives of photomosaics, controlled by the 1:5 million Mariner 9 and Viking data, produced by the USGS at Flagstaff, Arizona. The images are mosaics of Viking 1 and Viking 2 Orbiter high-resolution pictures placed on an air-brushed background based on earlier data from Mars. The mosaics were created at 1:1.25 million and scaled to 1:7.5 million. Each mosaic covers the areal surface for the Mars subquadrangle maps. The legend on the mosaics includes the Mars subquadrangle map number and the center coordinates in deg of longitude and latitude. Longitude and latitude lines at 5 deg intervals are shown where the base image is not covered by the Viking mosaics. Mosaic coverage of the subquadrangle areas varies depending on available images at the time of creation of the mosaics. Footprint sketches showing the Viking picture numbers accompany the mosaics. These picture numbers can be used in ordering individual frames making up the mosaics.
