Tutorial: Create a groundwater level map from borehole data and a DEM

1. Introduction

After this tutorial you'll be able to:

  • Load a borehole/wells dataset from an SDI into QGIS
  • Calculate the density of the boreholes in a polygon
  • Download the SRTM 1-Arc Second DEM
  • Clip and reproject a DEM
  • Style a DEM
  • Sample elevation at the borehole location and compare it with the elevation attribute
  • Make corrections and calculations in the attribute table
  • Interpolate groundwater levels of the boreholes to a raster
