I have created a raster surface that is made up of elevation (z) values. I also have pts with z values that fall above and below this 3d surface. These are consecutive pts that in certain instances pt 1 may be below the raster surface and pt 2 may be above. What I need to do is connect these pts (and many others) with a line and find out where that line intersects the raster surface and extract that raster value for that cell.
Any help would be much appreciated.
