The Lunar Orbiter Laser Altimeter (LOLA) Gridded Data Record Roughness Counts (GDRDRC) data products are the data counts (samples per pixel) used to generate the roughness maps (GDRDRM). The GDRDRC data products contain the binned, interpolated altimetric measurements on a uniformly-spaced grid. The data are derived from LOLA RDRs, geolocated using high-precision GRAIL-based GRGM900C orbit solutions.
Global standard products use the Equirectangular map projection, also known as Simple Cylindrical, while products with polar coverage use the Polar Stereographic projection.
