This thread Reprojecting raster from lat/lon to UTM in R? was of no help to me.
I have the following raster which I first need to create in lat/long in order to crop it to rworldmap. However, I then need to work in UTM. How do I convert the raster to UTM? The above thread just assigns the UTM projection from the start, which I know how to do. I just don't know how to convert back.
# Make raster layer of study area ras = raster(ext=extent(-70, -55, -60, -38), res=c(0.01,0.01)) #give all ponints a "1" ras <- 1 #project the grid to lat/long projection(ras) <- "+proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0" # load land library(rworldmap) worldMap <- getMap(resolution = "high") projection(worldMap) <- CRS(proj4string(ras)) #crop and mask raster by land r2 <- crop(ras, worldMap) r3 <- mask(r2, worldMap, inverse = T) plot(r3) #convert raster back to UTM ....??
