Dear all, I have a jpg map of altitudinal contours in my study area which I would like to map and use in R to calculate the altitude and slope of GPS coordinates. So far, I have painstakingly traced these contours in ArcMap to create a shapefile (of polylines) with altitude. I have now imported this file shapefile into R.
What I would like to do is turn it into a raster of slope and altitude, but I can't seem to find any method of doing this in the online R help archives. Does anyone have any idea which package I should be using, or perhaps if it is even possible to turn this type of shapefile into a raster? Thanks in advance!
