Hello, I have municipalities (preferred as polygons, but point features also possible) with "journey time" from a central location as a continous metric attribute. For about 5 percent of the municipalities the attribute value is missing and I want to automatically generate a value for these features. I have tried interpolation with inverse distance weighting which produces good results as raster data. However, I haven't figured out how to get values from the raster transferred into the original polygon or point features' attributes. Now my questions are: - How can I transfer values from raster data into (given) point or polygon features? - Is there solution other than interpolation which is more practical? For example, it would be sufficient to generate an average value from all bordering polygons or points within a certain distance. Thank you for your help! Regards, Alex
