Hi,
In fact, now it seems to work, I had a problem in my data input. Otherwise, I
have a model of terrain larger than my orthoimage, do you know how to cut the
terrain model to obtain only the part with the orthoimage? Are there any
options of VPB for this?
Thank you!
Cheers,
lucie
Hi Lucie,
to cut your terrain you can use a lot of tools...google is your friend,
you'll find a lot of info on that topic.
If you have the budget for it, one of the most convenient tool is
probably GlobalMapper: http://www.globalmapper.com/
Of course gdal_translate can do it too:
Hello Pierre,
I send you in attachment what I get in my console with OSG_NOTIFY_LEVEL =
INFO when I run osgdem --geocentric -d data.dem -t data.tif -l 3 -o data.osg
and when I run osgviewer data.osg.
Otherwise, I use osg-2.8.2, VPB 0.9.10 and gdal 1.5.
I will try to use Boston data.
Thank you!
Hi,
I tested the boston example but I'm not sure that the projection has worked
well.
I run osgdem.exe --geocentric -d boston-dem-downtown-5m-utm19n-meters.tif -t
boston-10m-utm19n-meters.tif -l 5 -o test2.osg.
I send what I obtain in attachment.
Can you tell me if it worked well?
Thank you!
Hello Lucie,
When looking at your log I see that the tiff texture is reprojected...

Hi,
I tried everything you told me but the projection does not work.
When I run gdal_info data.tif, I get :

Coordinate System is:

Hi,
I also tried with dem and orthoimage downloaded at:
http://www.geobase.ca/geobase/en/index.html
I get the same problem, the projection doesn't work.
With gdal_info data.dem, I get :
Driver: USGSDEM/USGS Optional ASCII DEM (and CDED)
Files: 013c07_0100_deme.dem
Size is 1201, 1201

Hi Lucie,
maybe you could try to use the OSG_NOTIFY_LEVEL=INFO flag to know a
little bit more about your problem...
What are the version of osg, vpb and gdal you are using ?
Also you could maybe try to use some known to work data like the Boston
sample of the OsgGis project ?
and dt1 files...
