  1.  Advanced users may be interested in getting the development versions of GRASS 6 (version 6.5) and GRASS 7. This is only possible if you have installed the Apple Developer Tools on your machine, and the KingChaos frameworks required for the GRASS 6 binary (http://www.kyngchaos.com/software/frameworks). Once these are installed, get the GRASS source code (http://trac.osgeo.org/grass/wiki/DownloadSource) and open a terminal window.

    Source configuration can be initialized like this: (from the command line)

    export NAD2BIN=/Library/Frameworks/PROJ.framework/Programs/nad2bin

    ./configure \
    --without-motif --without-glw --without-odbc --without-cairo --without-readline --without-postgres \
    --with-opengl=aqua --enable-sysv --with-x --with-cxx \
    --with-freetype --enable-largefile --with-wxwidgets \
    --prefix=/Applications --enable-macosx-app --with-macosx-archs=i386 \
    --with-includes=/usr/include \
    --with-libs=/usr/lib \
    --with-proj-includes=/Library/Frameworks/PROJ.framework/unix/include \
    --with-proj-libs=/Library/Frameworks/PROJ.framework/unix/lib \
    --with-proj-share=/Library/Frameworks/PROJ.framework/Versions/4/Resources/proj \
    --with-tiff-includes=/Library/Frameworks/UnixImageIO.framework/Versions/C/unix/include \
    --with-tiff-libs=/Library/Frameworks/UnixImageIO.framework/Versions/C/unix/lib \
    --with-png-includes=/Library/Frameworks/UnixImageIO.framework/Versions/C/unix/include \
    --with-png-libs=/Library/Frameworks/UnixImageIO.framework/Versions/C/unix/lib \
    --with-sqlite \
    --with-sqlite-includes=/Library/Frameworks/SQLite3.framework/Versions/3/unix/include \


    Adjust the configuration above to taylor GRASS to your needs, i.e. add postgresql support etc.

    If configure finished without error, compile and install the software with:
    make && sudo make install
    See the macos specific README within the GRASS source code for further discussion of the process.

  3. Put all AST*.zip files into one directory.  
    Then, in the GRASS GIS shell terminal, cd into this directory and run:
    # unzip all files in a loop:
    for map in `ls A*.zip` ; do unzip $map ; done
    # import and set elevation color table
    for map in `ls AST*/AST*num.tif` ; do
         r.in.gdal input=$map out=`basename $map .tif` -o
         r.colors `basename $map .tif` color=elevation
    # set computational region to include all imported maps (the list of DEM names we retrieve automatically):
    g.region rast=`g.mlist rast pattern="AST*"` -p
    Now you can display and analyse the ASTER GDEM maps. If you want to mosaik the DEM tiles into one single map, use r.patch:
    r.patch input=`g.mlist rast pattern="AST*"` output=complete_ASTER_GDEM
    r.colors complete_ASTER_GDEM color=elevation
