Hi 1. I have two raster files *.asc (identical size) 2. The data in each contain presence or absence data in each cell represented by a 1 or 0 respectively 3. I would like to take the location of each 1 (presence cell) in raster file 1 and measure the euclidean distance to the nearest 1 (presence cell) in raster file 2.
Obviously in some cases there will be overlap so the distance will be zero. 4. I would like the output file to have each individual measurement on a seperate line in a single file. I am very new to R, so any help would be appreciated.
