I think the closest it can get with current QGIS abilities is to use halo (or background) effect with color sourced from table which will be based on the elevation value and color scheme same as used for underlying grid. Of course this would not take into account hillshade and everything else below the halo in the map. Random color example: With some bit ...


Yes, doable. Normally I'd suggest a partially transparent buffer, but I see why you want to do this cartographically. This could be slow, and you need to manually decide where you want the labels to go - but cartographically speaking, that's not a bad thing! Here's a screenshot... As you can see, no buffers. The raster underneath is unaffected. I've ...

here is a video for ArcGIS 10 on contours that should help. You need to use a DEM as an input. It is a raster file.


Assuming you have a vector layer with the elevation as an attribute, you can open the attribute table and click on the column title of the elevation field. This will change the sorting from low to high and from high to low (or the other way around). You can also use the statist plugins to get statistics of that field.
