problem in krige function
temiz wrote:
following the topic GRASS and R kriging interpolation from grass6 tutorial
I came here without problems
But here:
zz <- krige(z ~ 1, locations = el1 , newdata = mask_SG , model = efitted)
Error in predict.gstat(g, newdata = newdata, block = block, nsim = nsim, :
var1 : data item in gstat object and newdata have different
coordinate reference systems
how can I solve this problem ?
How about making sure they are equal? If you know they are equal, do proj4string(el1) = CRS(proj4string(mask_SG)) else use spTransform from rgdal to re-project. gstat checks that the projection strings are exactly equal; this is a check too strong, and should be replaced by some check that they represent exactly the same projection. Does anyone know how to perform this check? -- Edzer
