Interpolating vegetation map

Added by Guilherme Martins over 7 years ago

Hi all,

I'd like to interpolate my vegetation map, but I'm not sure that operator I have to use. I don't know if I can use remapbil in the categorical values like in my map.

My file is in attchment and your resolution is 10km and I'd like to interpolate to 50km resolution.

Can anyone give me a tip?

My file information.

#
  1. gridID 1 #
    gridtype = lonlat
    gridsize = 6480000
    xname = lon
    xlongname = longitude
    xunits = degrees_east
    yname = lat
    ylongname = latitude
    yunits = degrees_north
    xsize = 3600
    ysize = 1800
    xfirst = -179.95
    xinc = 0.1
    yfirst = -89.95
    yinc = 0.100000000000009

Thanks,

Guilherme Martins.

Hi Guilherme,

Interpolation between different categories often doesn't make sense. I would recommend to use the operator remaplaf for categorical values. This operator find the category with the largest area and use exactly this category without any changes.

Cheers,
Uwe
