Hi!
I have using osgdem. My input dates are file: .tiff
with lat/lon/elev. I obtain a file and its
representation is correct.
But I want to add 3Ds models, so, I obtain the z of
the terrain and observe that the coordinate z of the
center of terrain is not correct. How I can obtain
that coordinate?
Next, I put the head of the file .osg:
CoordinateSystemNode {
DataVariance DYNAMIC
nodeMask 0xffffffff
cullingActive TRUE
Format "WKT"
CoordinateSystem "GEOGCS[\"WGS
84\",DATUM[\"WGS_1984\",SPHEROID[\"WGS
84\",6378137,298.2572235630016,AUTHORITY[\"EPSG\",\"7030\"]],AUTHORITY[\"EPSG\",\"6326\"]],PRIMEM[\"Greenwich\",0],UNIT[\"degree\",0.0174532925199433],AUTHORITY[\"EPSG\",\"4326\"]]"
num_children 1
PagedLOD {
DataVariance DYNAMIC
nodeMask 0xffffffff
cullingActive TRUE
Center -1.638410091400147 41.35421371459961
0.002561626955866814
....
In summary: The elevation that appears in the center
of coordinates (red colour) must be 530 m because This
is the value that I obtain when I open the image in
Erdas software.
Where is value and How can I solve it?
Thanks,
Neus Aparicio Ferrando
