I'd call this an early pre-release, especially because you have to hack the coordinates of your preferred location into the URL, but it could help working towards a solution to this issue. I've set up a Mapserver on our Landcover-DB that contains lots of funny stuff - including three different sources for shoreline data. Please, _please_ read _before_ everyone enters the URL into their web browser :-) While the machine performs quite well as WWW-, FTP- and database server (as well as our local fileserver !), is was not sized to to the job of an online web mapping server. The server is running only with 256 MByte of RAM at a 400 MHz clock cycle, so please take care with these rare ressources - try to use it asynchronously ;-) In the Mapserver page you can select different layers. The DB contains all layers that are being used for the current Scenery (and some more) but not all layers in the DB are listed in the drop-down chooser. The single reason for this constraint is that I simply didn't find the time to determine colours that represent all those different landcover types in a reasonable manner .... Somewhere down the list you'll find 'landmass_default', 'swbd' and 'gshhs coastline'. The first is from VMAP0 and seems to represent political boundaries, the second is the SRTM water body data, the third - you name it. So, here you are: http://document.ihg.uni-duisburg.de/landcover/ SWBD contains some really interesting details that others don't because it is a real 'picture' of the current situation when The Shuttle came by. This means it doesn't know about tides .... some small islands are represented with the double of their actual width because of low tide. There is notion of lakes where not lake actually is - maybe because of strong rain falls. Some lakes don't show up in any of the three datasets .... VMAP0 is about political boundaries so it appears not so much to care about small details in the shoreline. GSHHS is very accurate at those places where I had a look at and is now split into four categories: coastline, lakes, islands in those lakes, ponds on those islands. Please have a look and try to determine which one matches best. The map starts at Lake Constance with VMAP0 lakes only. The pan-buttons in the corners currently don't work (I'll have to look after this) but you can click into the map to re-center it. You also can enter the respective coordinates in the 'imgext' part of the URL. I'll soon have a modified page where you can enter a location for the start. Have fun, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -------------------------------------------------------------------------- ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
