The background image is clipped from the LRO LROC NAC high-resolution controlled mosaics at Apollo 15 landing site (
nac_roi_apollo15lob_e259n0038, 1.4m/pixel). The middle of the map is a small subset of LROC ortho-image (
NAC_DTM_APOLLO15_M111578606_50CM, 0.5m/pixel) with visible tracks. Both data products were produced using USGS ISIS by the LROC team at Arizona State University. The traverse line is from Phil Stooke, University of Western Ontario. It was created by tracing tracks visible in the LROC data as well as using surface photos and descriptions.
