The simple way to interpolate a set of point elevations to a DEM is with the gdal_grid tool. It appears in the QGIS menu: Raster->Analysis->Grid(Interpolation). You need to choose the interpolation method, which column contains the Z values, and the final grid resolution that you want. HTH ------ Original Message ------

Hello! I need to create a digital elevation model for the visualization of an old landscape based on archaeological data. Usually I'm working with AutoCAD, but this software has no capabilities for DEM. My option is now QGIS!My data is an xyz-file. I managed to import this file into QGIS. Nice green points! My CAD trained brain now thinks, this layer has to be marked and a tool for making digital elevation models has to be started. But this does not work. It seems to me, QGIS wants to load a rasterlayer. I have got no rasterlayer, just my points... Can anyone help me? GIS workflow is very confusing to me... -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Elevation-model-from-xyz-data-GIS-archaeology-tp5252164.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list [email protected] List info: http://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: http://lists.osgeo.org/mailman/listinfo/qgis-user This mail was received via Mail-SeCure System.
