After 5 years of continuous growth the deegree project currently provides the most comprehensive implementation of OGC/ISO standards in the Free Software world. To support the community process the first get together of users and developers will be held on June 8, 2006, at the University of Bonn. deegree day is designed to be a platform for interaction between users and developers, and knowledge exchange. Developers will present both current and upcoming features. Users have the opportunity to report on latest project solutions. Pressing open issues in technology, communication, and project organization will be discussed on deegree day. The preliminary agenda covers plenary sessions and parallel work shop tracks, including presentations, tutorials and discussion. Call for Papers We invite you to submit papers to be presented at deegree day. Papers should be of general interest to the conference participants and be related to the deegree project. This is a good chance to document your project results and your expertise and to discuss solution strategies with experts and users. Please send your abstract to: deegreedaypapers at deegree.org Abstracts should be a maximum of 1000 words and are due no latter than May 11, 2006. Proposals will be evaluated by the programme committee and those accepted will be included in the online Conference proceedings.

I think GRASS has some triangulation routines, but I don't think there's a routine to generate contours from the triangulated mesh. Maybe I'm wrong? Any other suggestions?

Do you have > experience? The i.ortho.photo implementation follows the algorithms described in this book: Elements of Photogrammetry, With Air Photo Interpretation and Remote Sensing by Paul R. Wolf, 562 pages Publisher: McGraw Hill Text; 2nd edition (January 1983) You can still find it for a few Euros/Dollars. In GRASS 5, there is a src/libes/image3/ library which is an extended version including LANDSAT ortho-rectification but it was never completed (as far as I know). Related commands are i.points3 and i.rectify3 in GRASS 5. It would be great if capable programmer(s) make this code (treasure?) ready for GRASS 6.

I have looked at converting SRTM files into XYZ but this means a 50gb database for Australia - a little to big for me at this stage - but if I have to then OK. are they any tools that will do this for me?? or a webservice that I can use to query SRTM files??

So it is doable, good. But, being a complete Postgres/Postgis ignorant I'd prefer some other solution if possible. Anybody? If there is really no other way, I'll have to try Postgis.

Lines are labeled with UTM easting and northing values.

Then v.in.ascii and voila'. Untested: A better solution is to use v.example [1] and just invert the reading order (descending instead of ascending) for each line and write it out. But I am not sure why you need this. GRASS is supporting forward *and* backward direction. So you could just modify the line attributes.

I need to: 1. turn my lines of watercourses in the proper direction - the way the water flows 2. transform stream's ending nodes to points (v.to.points, easy) 3. upload the DEM elevation under each stream node into datatable (v.what.rast, dito) 4. calculate whether the cell under the ending stream node is lower than the one under the starting node, as to DEM elevation (easy with 'along' attribute we have from v.to.points) 5. if starting is lower than the ending one, lower DEM under the starting one as needed 6. feed my watercouses and the modified DEM into CachmentSIM GIS; it will enforce drainage direction on the DEM, based on watercourses location and the difference in elevation of starting and ending stream cell http://www.toolkit.net.au/catchsim/index.htm?Overview/WatercourseInterp/WaterCFrame.htm~mainFrame (they are talking about the case when the input is contour lines, but feeding a ready-made DEM and eforcing drainage right over it is also possible, and that's what I'm gonna do) Weird, but will work.
