Just a quick video to show you how to extract vector line contours from points by creating a raster from TIN (Triangulated Irregular Network) Interpolation. QGIS - qgis.org Spatial Modelling Solutions - smsgis.co.za
Hi, I wondered if you have a video to show how you incorporate breaklines into your contours for where you may have a cliff edge etc? Would be grateful if you could assist. Thanks in advance.
Hi, I have a problem with the TIN. I just started using QGIS because I no longer have access to ArcGIS. I want to create a lake bathymetry map from depth survey points. I created a polyline and converted it to a polygon so I can contain the interpolation within the shoreline boundary but when I run the TIN, it does not recognize the shoreline polygone as the extent and it interpolates out of that. What is wrong?
