Hi John, Jag has finally implemented a netCDF file using the projection and the 2 vectors to geo-locate the pixel values in IDV. You can find examples of these netCDF files under the following FTP server. ftp://ftp.eumetsat.int/pub/EUM/out/USD/Unidata_test_files We've noticed that in IDV, the projection generated for these files looks correct but it takes a very long time to load the pixels' values for 1 channel into the projection (takes hours). Can you pass these files to the IDV team to see why its taking so long to load them (Note: we tried allocating the a lot of memory to IDV (3GB) with no improvement in loading times). Regards, Pete.
hi peter: yes this looks good (see attached).I loaded in IDV, using "Color Shaded Plan View". Slow, but not impossible. The default "Contour Plan View" was so slow i didnt wait for it.
Ive forwarded this to idv-support (remove that if you reply to this email)(support: file is in /upc/share/caron/MSG2_W_XX-EUMETSAT-Darmstadt,VIS+IR+IMAGERY,MSG2+SEVIRI_C_EUMG_20100927130009.nc).
Also can try in toolsui:http://www.unidata.ucar.edu/software/netcdf-java/v4.2/webstart/netCDFtools.jnlp
go to FeatureType/Grid, enter filename, hit the red alien, then in that new window, hit the red alien.
its a very large image, nothing really else to do to speed it up, other than use a stride when you dont want/need the full detail.
congratulations! john
