"I would like to calculate the Euclidian distance from a residence to a public service of interest e.g. the distance from a residence to a green space (as the crow flies) in QGIS. After browsing the Internet it seems that I need to rasterize my vector before I can use the Proximity tool provided by GDAL. When I try to make the conversion from vector to raster my thought was to take the shp.file which contains the polygons. The function "rasterize" tells me to chose an "output file for rasterized vectors (raster)" but I have no idea what to chose here. Should I create a raster for this? And how do I this? I'm using QGIS 1.8 Mac and GDAL 1.9. Thanks in advance."
Ok, it seems like I have not done my homework good enough. Let me start over: I have a vector layer with points from which I want to calculate the distance to vector layers with lines or polygons. Still I want to calculate the Euclidian distance (as the crow flies) from the points in the first layer to the lines or polygons in the other layers: The distance from a residence (point) to a stream (line) or forest (polygon). Additionally, I would like to put the distances in the attribute table of the vector layer with points in a new column. Sorry for the inconvenience.
