Is anybody able to offer some ideas on how to render hillshading/colour-relief in areas with coastline?
I have used the methods described in the OSM wiki and elsewhere to get nice colour-relief tiffs. I can render images using these so long as I put the layer(s) containing the tiffs first. The problem comes around the coastline. I think that I really need to paint the coastline using the processsed_p shape file (as the images produced from the SRTM data aren't good enough to define the coastline - especially with low lying islands). Clearly, if I just paint a filled coastline on top of the hillshade, I lose the hillshade and vice versa. I've tried lots of things but without the success that Opencyclemap have clearly achieved. http://www.opencyclemap.org/?zoom=12&lat=55.65104&lon=-1.85604&layers=B000 The best I've achieved is to use the linesymbolizer to draw round the coastline shapes rather than fill them - but this is both a bodge and it inevitably draws spurious lines.
