<br>
I have 10x10 meter cell sized, 1 meter precision elevation data,
but I have to create a contour map that features 0.5 meter steps<br>
hence the current level of precision is insufficient. Can I do
this with grass gis?<br>
<br>
I tried the fallowing command, but I didnt get what I want,
beacouse it create the .5 meter countours as the .0 meter
countours 10 meter buffered line. <br>
<br>
r.contour input=ddm-10 output=contour_05 step=0.5 cut=0<br>

Does the raster have integer values or floats?<br>
try r.info -t ddm-10<br>
<br>
If it's a CELL type, then do:<br>
r.mapcalc ddm-10_float=1.0*ddm-10<br>
to create an equivalent floating point raster.<br>
<br>
Then rerun the r.contour command<br>
