HelloI have a geotiff file of sea ice concentration.When I use gdal_info it
gives a series of values like:
Metadata:
COLORINTERP=Palette
Color Table (RGB with 65536 entries)
0: 9,60,112,255
1: 9,60,112,255
2: 9,60,112,255
3: 9,60,112,255
4: 9,60,112,255
5: 9,60,112,255
6: 9,60,112,255
7: 9,60,112,255
8: 9,60,112,255
9: 9,60,112,255
10: 9,60,112,255
etc...
When I use gdal_translate to convert to netcdf:
gdal_translate -of netCDF test.tif test.nc
and I look at the values in the test.nc file
...

-1362500 4212500 216
-1337500 4212500 316
...
My question is: when gdal_translate convert to netcdf what does the value in
the third column represent?
Points that are equal to 2540 seem to be land cells, while points with 0 value
are ocean cellsAre points with value rating from 0 to 1000 (where sea ice
concentration exists) in per thousands? (i.e 100 = 10% sea ice concentration,
1000 = 100%?)
