Re: [R-sig-Geo] Spatial Downscaling in R

Thank you for your replies. I will try with the packages you mentioned - they look very useful, I guess my issue is that all I have a vector of global mean. Thanks again! Sincerely, Milu On Thu, Mar 15, 2018 at 9:34 AM, Bede-Fazekas Ákos wrote: > Dear Milu, > > You can

Re: [R-sig-Geo] Spatial Downscaling in R

For downscaling, and especially if you work with relatively smooth surfaces and large rasters, I recommend using gdalwarp cubicspline technique e.g. (http://www.gdal.org/gdalwarp.html): gdalwarp input.tif output.tif -r "cubicspline" -tr 250 250 -co "COMPRESS=DEFLATE" If you prefer to do

Re: [R-sig-Geo] Spatial Downscaling in R

Dear Milu, You can use any spatial interpolation method as statistical downscaling approach. See package gstat for IDW (inverse distance weighted) and several types of kriging. In case of temperature, you might use elevation data from a DEM or radiation data as auxiliary variables in those

Re: [R-sig-Geo] Spatial Downscaling in R

Try ClimDown package, otherwise more generally raster function disaggregate. Cheers On Thu, 15 Mar 2018, 06:53 Miluji Sb, wrote: > Dear all, > > Please forgive my inexperience with spatial downscaling. I am interested in > spatial downscaling of global temperature to grid

[R-sig-Geo] Spatial Downscaling in R

Dear all, Please forgive my inexperience with spatial downscaling. I am interested in spatial downscaling of global temperature to grid cell. Is there a package in R that can perform this function? Any help/guidance will be highly appreciated. Sincerely, Milu [[alternative HTML
