{jcomments on}This beginner QGIS tutorial explains how to generate contours using a points dataset. The points dataset used in this tutorial was created in the first half of this two part tutorial, called ‘How to sample raster datasets using points in Quantum GIS (QGIS)’. That tutorial explains how to create a regular grid of points and effectively sample the raster elevation values for use in the contour plugin.

Note: This tutorial can be completed with any other point dataset as long as it has an elevation attribute column associated with the point data.
