I have a map made of many different vector layers. There is a contour layer of polylines. I also have DEM data in a .gdb file with lots of MultiPolygon data it in.
I'm using QGIS/OSGeo4W64 and I would like to add shading to show the elevation changes. I read a bit about hillshading and I've found some instructions but it all seems to deal with raster data. As far as I can tell the .gdb file is all vector data. Do I work with the contour vector layer? Or, do I work with the DEM data in the .gdb file? Are there qgis plugins that will help? Do I need to deal with colorramps?
