Preliminary digitization of lunar lobate scarps between 60N and 60S latitude.

Map of lunar lobate scarps digitized as polylines. Digitization completed on a monochromatic (643nm) LROC Wide Angle Camera (WAC) image mosaic, optimized for geomorphology, at a resolution of 100 meters/pixel, where available LROC Narrow Angle Camera (NAC) images at resolutions up to 2 meters/pixel, and regional NAC mosaics. Near-global coverage, limited to the equatorial region between 60N and 60S latitude. Polylines were digitized at a scale of up to 1:20,000. Minimum digitized segment lengths of approximately 300 meters.
