I guess mine is a very simple task, however I don't know how to solve it. I m trying to display the outlines of a raster created from a polygon shp. What I would like to come up with is an image where I can visualize the outlines of each poligon within my raster image. This image has two different colours (namely two "classes") and one is switched off, so only one is visible. Here is an example of what I need (but this is a shp, my image now only displays the yellow parts, while I also need the black lines):
I work both with ArGIS 10.1 and QGIS 1.8. Any idea?
