Craters 5 km to 20 km in diameter (60S to 60N, 90E to 180E). 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 90E to 180E 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.
