mhm.. I think of that (and you may not be the first who asked something like that) then that would need to be programmed as a new type of mouse tool. A cumbersome approach would be to draw lines from source to target (attach the point attributes) and then calculate the length of those.
but did you play around with PostGIS? ..because in postgis you could do a SQL query for that - I think. shall I consider this as a feature request for a new function? (i.e. select a item and select a layer and compute all distances to the selected item and attach those as new attribute) stefan Rahkonen Jukka wrote: > Hi, > > Is it possible somehow to count the distance of features from one > selected feature?
