LOLA data for candidate South Pole landing sites

Each directory contains 5 m/pix GeoTiffs with south polar stereographic X/Y coords in meters, MOON_ME reference frame of ephemeris DE421.

X/Y coords follow the Generic Mapping Tools 'pixel-registered' convention (i.e., they are the centers of the pixels).

*_surf.tif : surface height Z (meters) with interpolation filling empty pix
*_ldec.tif : LDEC map, number of LOLA returns in each pixel
*_toterr.tif : Total Z uncertainty in meters (formally, the RMS error)
*_slp.tif : Slope (degrees)
*_slperr.tif : Slope uncertainty in degrees (formally, the RMS error)
Clones/ : Directory containing 100 clones of LDEM

Also in each directory are the data that make up the LDEMs:
*.xyzi - final point clouds after track adjustments and cleaning
Data format: Binary double precision floating point tables with 4 columns: X, Y, Z, RDRid
where X,Y,Z are the polar stereographic coordinates (in km) and RDRid is the LOLA RDR ID for each point with the format: YYDOYHHMM
*_ROIs.tgz - archive containing shapefiles (for GIS)
