This video demonstrates, step by step, how to create contour lines and DEM ( Digital Elevation Model) using free tools : Google Earth, TCX Converter and QGIS 2.10.

You know that QGIS can generates DEM and contours from a points cloud which contains altitude information.

So, we used the Path tool in Google Earth to create the points cloud and we exported them to a KML file.

Then, we used TCX Converter to get altitude data of the points (internet connection needed) and export them to a CSV file.

Finally, we imported the CSV in QGIS 2.10 and we used SAGA tools to generate a DEM and contour lines.
