Dear ferret user,
I would like to say my sincere apology in this mailing list, especially to William.
I just realized that I am not careful in set the step of degree.
Now I can start to use my data using suggestion command from William.
yes? define axis/x=114.3389435E:115.1776276E:0.00453/unit=degree longitude
yes? define axis/y=8.0546379S:8.7746868S:0.00453/unit=degree latitude
yes? define grid/x=longitude/y=latitude bathymetry
yes? file/format=(186f12.3)/var=ps/grid=bathymetry/columns=186 bathy_input.btm
yes? set data bathy_input.btm
yes? show data
And the result:
currently set data sets:
1> C:\Program Files\TMAP\fer_dsets\data\bathy_input.btm (default)
name title I J K L
ps ps 1:186 1:160 ... ...
and I also try this command:
yes? set grid ps
yes? show grid ps
grid ps
name axis # pts start end
longitude longitude 186mr 114.34e(114.34) 115.18e(115.18)
latitude latitude 160r 8.774s 8.052s
normal Z
normal T
Thank you very much, I will try to learn for next command.
Kindest regards,
dessy
