Re: [osg-users] [vpb] Building a geocentric database with heigh data
Hi Mauricio, did you ever get your geocentric database with height data up and running? We are currently struggling to do the same, and are having similar problems. Osgdem works perfectly when using either a non-geocentric (flat) Earth model with height data or when building a geocentric database with no height data applied. However, when using both height data and the --geocentric option, osgdem always aborts with a message stating that the destination graph cannot be build. Perhaps we're using the wrong parameters, but I just wanted to check if it does work at all, or if support for geocentric databases might be broken at the moment (we've checked out vpb from the trunk). Thanks a lot in advance! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=12311#12311 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [vpb] Building a geocentric database with heigh data
Hi Timm, You really need to provide more information about what osgdem options you are using. It's normally trivial to generate databases with elevations, and to osgdem it doesn't make any difference whether its geocentric or flat earth, it works fine for both, and the majority of VirtualPlanetBuilder users will be doing just this.

Perhaps we're using the wrong parameters, but I just wanted to check if it does work at all, or if support for geocentric databases might be broken at the moment (we've checked out vpb from the trunk). I just successfully built a geocentric VPB database with osgdem using 90m SRTM data (geographic WGS84) in BT format and 30m Landsat imagery in four large geographics WGS84 tiles (from the Telascience archive of the OnEarth mosaic). I'm using VPB from SVN-head from last week. I made a couple of tweaks (submitted to osg-submissions) to allow setting the less-than-full build extents in geographic coords but those shouldn't impact your application. My commandline is roughly osgdem.exe -gb (my X,Y area bounds) --geocentric -t Image1.tif -t Image2.tif -t Image3.tif -t Image4.tif -d MyDEM.bt -l 10 --terrain -o MyModel.ive -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ There is no Truth.

Re: [osg-users] [vpb] Building a geocentric database with heigh data
I'm having a hard time reading the text in your attachment (maybe I'm going blind) but it looks like there may be some info missing in the tif files. Can you do a gdalinfo on the tif files and send us the output? Either that or you could just attach the actual tif files and we can look at them directly... -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Mauricio Sent: Wednesday, April 15, 2009 4:37 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] [vpb] Building a geocentric database with heigh data The source data are ordinary tiff files.

Perhaps you can provide more info on what osgdem reports when it crashes.
