Hi, this is my first time trying to use osgdem on a GeoTIFF file and I wasn't successful in viewing the generated osga file. The data (from http://webgis.wr.usgs.gov/ftphirise/index.jsp) look like this:
% ls DEM_1m_VictoriaCrater* DEM_1m_VictoriaCrater.asc.gz DEM_1m_VictoriaCrater.rrd DEM_1m_VictoriaCrater.aux DEM_1m_VictoriaCrater.tif DEM_1m_VictoriaCrater.prj % cat DEM_1m_VictoriaCrater.prj PROJCS["Plate_Carree",GEOGCS["EQUIRECTANGULAR_CYLINDRICAL_MARS",DATUM["D_MARS",SPHEROID["MARS",3396190,0]],PRIMEM["Reference_Meridian",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Plate_Carree"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",180],PARAMETER["false_easting",0],PARAMETER["false_northing",0],UNIT["Meter",1]] I then use osgdem command: % osgdem -l 2 -d DEM_1m_VictoriaCrater.tif -o test.ive -a test.osga % osgviewer test.osga But I didn't see anything when osgviewer first came up, but I know something is there because when I spin it, I see something spin by really fast. My question are: 1. Is the "-d DEM_1m_VictoriaCrater.tif" argument to osgdem all I need for a GeoTIFF file? 2. Is there a way for osgviewer to put the object in the center so I can see it or do I have to ask the USGS to generate the GeoTIFF DEM that has the DEM in the center so I can see? Thank you very much, Linh _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
