Craters 5 km to 20 km in diameter (60S to 60N, 0 to 90W). Vector map of lunar craters greater than or equal to 5 kilometers and less than or equal to 20 kilometers in diameter centered between 60S to 60N latitude and 0 to 90W longitude. The map base consisted of the monochromatic (643nm) LROC WAC morphologic map with a resolution of 100meters/pixel. Crater rims were digitized at a scale between 1:250,000 and 1:500,000. This is one part of a six part series of lunar crater shapefiles. When citing this product, use the following reference: Povilaitis, R. Z., Robinson, M. S., van der Bogert, C.
