In order to convert .tff -> .osga, run:

        osgdem -xx 10 --yy 10 -t filename.tif -l 3 -a archiveName.osga

For more information, refer to:

        http://virtualplanetbuilder.osgforge.org/
        http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/osgdem
        ~/plugins/Image/Image.txt
        osgdem --help

To load the .osga file into covise, the file needs to be included in:

        covise/config/monash.xml  ->   under <Image><Files> <nameInPluginsList value="filename" />  </Files></Image>

• osgdem is located at /home/covise/covise/extern_libs/src/VirtualPlanetBuilder/bin
• ivl.xml is a lab specific config. file
• sand.xml is a machine specific config. file

Data Workflow

First we need to decide which area to download. For UCSD campus the coordinates are:

• Latitude from 32deg 51' 33" N to 32deg 53' 12" N
• Longitude from 117deg 13' 22" W to 117deg 15' 18" W

Texture Data

TIFF image with texture data can be downloaded from seamless.usgs.gov. Click "Define Download Area by Coordinates" in National Map Seamless Server window. Make sure that National Elevation Dataset (NED) 1/9 Arc Second is selected. Output format: GeoTIFF The server will offer two images to download, because the area selected covers two stored tiles.
