Dear GRASS-User List,
I have a CSV file with X,Y,Z coords of 150 point in a time series (50
measuring).
I imported it in a for cycle of $i (1..50):
v.in.ascii input=su1_data.csv output=su1_v_$i format=point fs=';' skip=2 x=2
y=3 z=$iplus4 cat=0 --overwrite
and made surface with:
v.surf.rst input=su1_v_$i layer=1 dmax=25 dmin=5 zmult=1 tension=40
segmax=200
npmin=100 zcolumn=dbl_$i elev=su1_v_surf_rst_$i --overwrite
I displayed the maps with:
d.erase
d.rast su1_v_surf_rst_$i
d.legend map=su1_v_surf_rst_$i
and would like compare it visually.
The problem is, that the scaling
and coloring of surfaces is different by each map.
Is it possible to set with a parameter of v.surf.rst that
all maps legend should have use the legend
with the same highest and deepest point?
I don't find so a parameter.
Is there another solut ion to visualize the time series?
This is not a v.surf.rst issue, but a r.colors issues. You can either
create a customized color table in a file and use r.colors rules= to
apply these rules to all your maps, or, if you have one raster map which
is the reference map, you can also use r.colors raster=
