Hello everyone, I want to get a 1km by lkm grid raster image using my csv data. If I call latitude=a, longitude=b and preciptation=c.
a<-(1,2,3,4,5) b<-(6,7,8,9,10) c<-(10,20, 30,40, 50) Then I found an example in r help which goes like pts = read.table("file.csv",......) library(sp) library(rgdal) proj4string(pts)=CRS("+init=epsg:4326") # set it to lat-long pts = spTransform(pts,CRS("insert your proj4 string here")) gridded(pts) = TRUE r = raster(pts) projection(r) = CRS("insert your proj4 string here") Because I am new to R, I have no idea what to put into the proj4 string and all that. Can anyone help me on this? If there is a different way of doing this, that is also fine.
