Hello I'm an artists trying different ways of drawing contours in QGIS using points with income values. I was able to import a shp file with the data, create a layer with centroids of the census blocks and create another with
of the centroids and etc.
I tried clipping the water out of the contours with a vector layer of the boroughs but couldn't get it to work. I also tried creating the contours from an IDW raster but couldn't get the contours to work using extraction->contour.
How can I make the contours more smooth? I just want to create a 10 layer accurate and smooth contour map of income in NYC. What's the best way to do this w/o GRASS (had issues using it in QGIS) and SAGA (had issues installing on OSX)?
