How to combine information from raster and vector layers? That is exactly how it works. It took me some time to get used to YAGT (=yet another GIS-Tool :-) but in the end the effort payed off. Saga-Gis is really good with its modules. |

How to combine information from raster and vector layers? Yes, I noticed the problem with the multi-cell polygons too. That can be solved be adding geometries and then using the polygon-areas as a weight-factor. Problem is: calculating the geometries takes as long as generating the intersects, meaning forever :-) But it works. |

How to calculate raster statistics for polygons? THX for the idea. I was hoping to get this done without adding and learning yet another software. I will keep PostGIS in mind for later though. |

How to exclude missing values from raster layer? The ASCII-GRID/gdal-question has been moved to gis.stackexchange.com/questions/22791/…. gdal2xyz is perfect for exporting the data. The real problem is not getting data out, but getting processed data back in, with the correct projection and coordinates etc. That is very easy for vector-layers (just open the dbf of a shapefile in oo-calc) and apparently very difficult for raster. |

How to exclude missing values from raster layer? GeoTIFF with NODATA works, thanks. In the german version of QGIS this matter is very confusing because the setting is called "Kein-Datum-Wert" which means "No-Date-Value" or "No-Datum-Value". It does not mean anything like "No-Data-Value". Thanks for clearing this up for me. |
