I'm not sure I can parse your message here? You aren't building scenery yourself, but you are building a scenery building server??? I'm confused. There's no reason to get into trouble :-)) What we've been talking about for a while is a PostGIS database where the VMAP0 landcover data is being imported. After being done with this we are enabled to export the whole stuff as shapefiles - one file for each 'layer', each landcover type. This is why Ralf Gerlich started to modify the shapefile decoder of TerraGear. Using shapefiles for this type of data is convenient because the format is pretty common and flexible enough for our needs. In _my_ eyes - Ralf may comment on this if his goals are different, I also invite Norman to share his thoughts - the first big step in the process is to reach the state where Scenery can be built with landcover data exported from the PostGIS database, featuring identical results as building Scenery from stock VMAP0 files. In a second step we're going to refine the landcover data by importing work as Ralf and his friend already did for their area. We also might think about importing the VMAP1 and/or TIGER data and whatever is available under a license that meets our requirements. The whole process gives us the ability to merge and refine landcover data from many different sources - as we stick to a common interface by employing a PostGIS database - while maintaining a stable interface to TerraGear. The GSHHS shorelines for example are stored in the database as well. This gives everyone the chance to adjust their favourite river mouth to match the actual shoreline.

Ah, I forgot one: After the landcover part of the database has reached a satisfactory state we could think about storing contour lines as well, to override inaccurate terrain elevation data where it makes sense. This could happen in a manner similar to how Frederic Bouvier adjusts terrain elevation by inserting contour lines in FGSD, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -- ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

Ralf I have been wondering to improve a place in France in Provence surrounding the Mont Ventoux, the FG scenery gives some crazy visual situations with rivers climbing mountains or roads becoming rivers. The materials are not good , the mont ventoux top should be desert stone and not green grass Your Lake Constance result, could encourage me to work on that. You created additional tool: an addition to TerraGear for creating polygons from GRASS vector lines and points.

[Flightgear-devel] Custom Scenery for Lake Constance
Hello, some time ago I posted that I had some project for custom scenery around Lake Constance in the most southern part of Germany going. Now that the legal issues are solved I'm proud to present the first comparison screenshots :-) http://web44.netzwerteserver2.de/196.0.html The standard scenery (on the left of the pictures) is from today. And: No, the framerates are not representative. It's quite smooth on my Laptop under Linux (ATI Mobility Radeon 9600 M10). However, it could become tricky when all the roads and streets are added, which a friend of mine digitized. Actually I had to reduce them to major freeways and railroads as TerraGear choked on the smaller roads. Interestingly it's killed some time into the process by a SIGKILL which doesn't come from itself. I already had a look into the kernel logs but no out-of-memory-kill is logged and CPU-overload-killing would have seen SIGXCPU before. Besides: I have set no limits on CPU-load and memory is far from out when the KILL happens. I'll have to figure that out. We haven't digitised all area data (population, forest, etc.) around the lake yet so at some points it's just green, but as somebody living there I can tell you: The custom scenery is far more like the real thing than the standard scenery. ;-) For example, VMAP0 has a highway going nearly all the way through the area north-west of the lake. This highway does not exist. It was planned though, but never built. We already did quite a number of flights around the new scenery and now it's actually possible to navigate visually. VMAP0 is missing some of the towns so you never know what town it is you see below you ;-) Regards, Ralf ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
