Okay, we have a swamp in Ankeveen with lots of water and inside the water a myriade of little islands. I found the possibility of multypolygons and I have to investigate that in more depth. Also the layer stuff I want to understand completely. This is important when doing work on such complex natural feature as our swamp or marsh, I think.

This swamp came into existence when in the old days people dug out peat for their fuel in stoves and such. They appearently did that in a not so orderly fashion, because, as said, it left a myriade of islands. On the up side, it's now a much appreciated peace of semi-wild nature, adored by the good people of Ankeveen. It's also a beautiful place to go skating in the winter. Well, not so much in the last few years, because the temperature drops not often and long enough below zero, to make it freeze over.

I already did a lot of way-correcting and already I changed the class of some islands from natural:water into natural:wood. I also created a body of water with layer 1 and gave the overlapping islands of wood layer 2. So hopefully the water will lay under the wood. Let's see what happens in the 2 rendering engines the coming days.

I found out that Osmarender and Mapnik render the layers differently. That's tough to work with, since osmarender is the first to show at least something but Mapnik seems to do a better job. Only for the Mapnik render I'm already waiting two days, for my first addition to show up in there.

I also downloaded and installed OSMTracker on my HP Ipaq HX4700 and it looks like it's working just fine. I'm definitely going to use that to map the footpath's in the parks we have in our next door town of 's-Graveland. So lot's of fun work to be done here!
