    992. Once you have entered the AREA_LL project, import the elevation spheroid as below;
    10    "r.in.ascii input=~arsf/dems/geoid-spheroid/ww15mgh.grd output=wwgsg"
     10{{{
     11   r.in.ascii input=~arsf/dems/geoid-spheroid/ww15mgh.grd output=wwgsg
     12}}}

    12 3. Now you can exit AREA_LL, go back to your UTM project
     143. Now you can exist AREA_LL, go back to your UTM project
    1315   1. Import/Re-project the elevation spheroid as below;
    14    "r.proj -n input=wwgsg location=AREA_LL mapset=PERMANENT output=wwgsgUTM"
    15    2. Now elevate the DEM by adding the spheroid;
    16    "r.mapcalculator amap=yourDEMmap bmap=wwgsgUTM formula=A+B outfile=yourelevatedDEMmap help=-"
     16{{{
     17   r.proj -n input=wwgsg location=AREA_LL mapset=PERMANENT output=wwgsgUTM
     18}}}
     19   2. Now elevated the DEM by adding the spheroid;
     20{{{
     21   r.mapcalculator amap=yourDEMmap bmap=wwgsgUTM formula=A+B outfile=yourelevatedDEMmap help=-
     22}}}
