Prediction error for Ordinary Kriging
Hi ALL,
Can you please help me on how to determine the prediction error for ordinary
kriging?Below are all the commands i used to generate the OK plot:
rsa2 <- readShapeSpatial("residentialsa", CRS("+proj=tmerc

+ellps=intl +units=m +no_defs"))
x2 <- readShapeSpatial("ptna2", CRS("+proj=tmerc +lat_0=39.66666666666666

write geotiff with projection - RGDAL package
...s missing spatial reference so it cannot be projected, but it is displayed correctly. I guess somewhere i am doing a mistake when i define the projection in R. My code follows:
data.grid <- read.csv(x, header=TRUE)
gridded(data.grid) = ~East.m.+North.m.
proj4string(data.grid) = CRS("+proj=tmerc +lat_0=0.00000000000 +lon_0=-81.00000000000 +k=0.99960000 +x_0=500000.000000 +y_0=0.0000000 +ellps=GRS80 +units=m")
tr <- "e:\\JELA_veg\\test_gtiff\\test.tif"
writeGDAL(data.grid["class.pca"], tr)
