Hi
I am trying to get sst data for an area in NW shelf of Western
Australia. I got the images of the area and have processed them on
ENVI. I dont have any experience with IDL programming and I have been
reading through books to help me out but I am stuck now. I have hdf
files for each month of the year and I would like IDL to give me plots
of SST vs. Latitude/Longitude. Can any one please help me with it?
Below is the program I have already started
pro january2009
hdfid=hdf_sd_start('C:\Documents and Settings\Nayan\My Documents
\raw_data\2009\February\IMOS-20100505T144046_1851.hdf')
;index=hdf_sd_nametoindex(hdfid,'SST')
varid=hdf_sd_select(hdfid,sst)
hdf_sd_getdata,varid,data
hdf_sd_endacces,varid
;hdf_sd_end,hdfid
;tvcl,data
index=hdf_sd_nametoindex(hdfid,'lon')
varid=hdf_sd_getdata,varid,londata
hdf_sd_endacess.varid
hdf_sd_end,hdfid
print,londata[0],londata[n_elements(londata)-1]
;tvscl,data
tempvec=data[*,1000,1]
tempvec=tempvec*0.01
set_plot,'ps'
;device,file='C:\Documents and Settings\Nayan\My Documents\raw_data
\2009\February\test.ps'
plot,tempvec,yrange=[0.40],ystyle=1
;device,/close
end
I get an error which says 'HDF_SD_SELECT: Unable to select the HDF-SD
dataset (HDFID).
% Execution halted at: JANUARY2009 4 C:\Documents and Settings
\Nayan\My Documents\raw_data\2009\January\january2009.pro'
ANY HELP WILL BE APPRECIATED.
CHEERS
NAYAN
