    long list
    i have most of it but here are the links to the original data
    earth
    https://topotools.cr.usgs.gov/gmted_...obal_grids.php
    https://dds.cr.usgs.gov/srtm/version2_1/

    Mercury
    the pds global heightmap ( in pds "img" format)

    the height data
    http://pds-geosciences.wustl.edu/mgn.../mg_3002/gtdr/

    -- Now i have a repaired and cleaned up version of the venus data
    -- rework of the original data , and by chance i just the other day posted a lores 16384x8192 copy of it
    -- 16 bit unsigned with each value set to 0.5 meters in height

    jupiter and the rest are scattered on various sites


    if you are using MS windows " Bjorn Jonsson " has a comandline tool for pds
    "img2png"
    http://www.unmannedspaceflight.com/i...showtopic=4979

    gdal opens img files and converts them to geo-tiff's
    you need both the img and lbl files
    img == image
    lbl == lable

    example for mercury
    Code:
    gdal_translate MSGR_DEM_USG_SC_I_V01.LBL MercuryDEM.tiff
    now this WILL!!! be 16 bit SIGNED INTEGER format
