Model building
Now, we will build our model using all the data we have computed. We want to make a DataFrame of the elevation value, slope value, and an indicator variable indicating whether the location is unsafe or safe. First, load the elevation data corresponding to the safe zone:
dem_safe = read.csv("F:/Hands-on Geospatial Analysis Using R and QGIS/Chapter 10/Data/dem_safe.csv")str(dem_safe)# Remove id columndem_safe$id = NULLstr(dem_safe)
By investigating the output, we can be sure that we have, in fact, removed the ID column from dem_safe.
Now, load the slope data corresponding to the safe zone and remove the ID column as previously mentioned:
slope_safe = read.csv("F:/Hands-on Geospatial Analysis Using R and QGIS/Chapter 10/Data/slope_safe.csv") ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
