[ferret_users] importing an ascii file

[Antonio Rodríguez <antonio.raju@xxxxxxxxx>]

Hi,

I've tried to find a solution browsing the help archives, but I couldn't find one. My problem is that I have an ascii file with chlorophyll data in this format:

latitude longitude chlorophyll
  36.00   -11.00     0.126305
  36.00   -10.00     0.119080
  36.00    -9.00     0.102295
  36.00    -8.00     0.109347
  36.00    -7.00     0.130324
  36.00    -6.00     0.552572
  36.00    -5.00     0.597104
  36.00    -4.00     0.237877
  36.00    -3.00     0.231190
  36.00    -2.00     0.216570
  36.00    -1.00     0.205664
  36.00     0.00     0.180958

The data represent the concentration of chlorophyll for a particular day.
I've tried to define a new grid:

define axis/x=11w:1e:1/units=degree clorx
define axis/y=30n:47n:1/units=degree clory
define grid/x=clorx/y=clory clorgrid

then import the data

file/form=delim/type=numeric/grid=clorgrid  jun1.dat

but no way. Any help will be appreciated

Best regards,

Antonio
