Tutorial: Create a groundwater level map from borehole data and a DEM
Conditions d’achèvement
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
- Create and visualise contour lines
