     I am seeking information regarding the use of 1:24,000 DEMs to 
     calculate (approximate!?!) actual surface area in a topologically 
     diverse region.
     I am especially interested in any GRASS scripts, dot commands, methods
     ect. which would provide surface area estimates instead of planimetric
     area values.
     I am also searching for any work which analyzed the differences in 
     surface area estimation that result when 1:250,000 DMAs are used 
     instead of 1:24,000 DEMs in a region of substantial topographic
