    Default Where can I find heightmap real world data?

    Hello does anyone knows where I can download real world heightmap data? Both of moon , mars, earth and whatever else there is available inthe starsystem as heightmaps in grayscale?

    what do you need ?
    there are many sources for the earth - it depends on the resilution you need

    for the moon the current is the LROC-NAC stereo gridded data

    for mars the old MOLA data for the full planet
    or
    the stereo HIRIS and CTX data ( only a few places )

    for other things like mars's two moons there are 3d meshes , even some of saterns moons have meshes
    For Jupiter's moons there are a few that have some height data

    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)
    https://pdsimage2.wr.usgs.gov/archiv...EM/GLOBAL/IMG/

    jpg2000 version
    https://pdsimage2.wr.usgs.gov/archiv...OBAL/JPEG2000/

    Venus
    http://pds-geosciences.wustl.edu/mis...gxdr/index.htm
    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
    https://drive.google.com/file/d/0B6Z...ew?usp=sharing


    Mars
    the mola data
    http://pds-geosciences.wustl.edu/mis...mgs/megdr.html

    -- 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
    https://drive.google.com/file/d/0B6Z...ew?usp=sharing

    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

    Useful post, thanks John. I used to have a list but my links are probably out of date now. You seem to have high res versions of all the non gas giants.

    I have an earth heightmap, it's 16 bit @ 300 ppi and 4 pixels per mile, if you want some of it. I'd love to post the whole psd file but it's 23g and I have no way that I know of to host or transfer that much data. I forget the source of it and the original resolution and all that but later when I can open the file I will post a bit so you can see if it's any good for you.
