comment How to merge two rasters when are on the same place
Do you want to visually blend them (r.blend) or truely merge the values? If the latter, what if both have a pixel value in a certain position?

comment GRASS GIS : ScriptError : Unable to fetch interface description for command 'd.rast'
Can you consider to update your installation? GRASS GIS 6.4.3 is rather old (latest stable is GRASS GIS 7.0.0, see grass.osgeo.org/download)

comment GRASS make local relief error
In general GRASS GIS 7 is able to manage huge datasets in the multi-GB size. Is your current region really rows: 12500, cols: 10000? Can you edit your posting and add the output of g.region -p just to better understand the problem?

comment Is this error “invalid context…fatal error” due to GRASS GIS bug or the system?
Hard to say without knowing which GRASS GIS version you are using... we had such an issue in the past which got fixed since then.

comment Duplicated vertices in contour features of GRASS?
Note: r.contours of GRASS GIS itself will not create duplications since it is a topological GIS. They must originate from somewhere else...

comment DEM with bathymetric contour lines in GRASS
Note the non-square pixels - better to use the align flag -a of g.region with res=XX to set it properly (you need to do that at the very beginning of your workflow to not propagate odd resolution throughout your work).

For zonal statistics, you can also use r.univar, v.rast.stats, v.vect.stats (see at page bottom of grass.osgeo.org/grass70/manuals/…)
