5. CONCLUSION 
We are able to virtually navigate over SPOTS scenes and now, 
we wish to treat in the same manner the future images of the 
future high-resolution satellites as Pléiades-HR. We saw that, in 
order to take into account these images (with sub-meter 
resolution), it is necessary to increase the resolution of the 
geometry on which the image is mapped. This increase in data 
resolution imposes to consider all the various objects 
constituting the scene (buildings, trees, etc). 
We set up an automatic data processing sequence allowing to 
solve the many problems of consistency of available data and to 
carry out all the treatments needed to merge in an exact way the 
3D data into a traditional DEM. These merged data are from 
now on available for any virtual overflight. 
Finally, we wish to bring a solution to the problem of textures 
for the building walls. After a geometry simplification step. we 
wish to perfect an automatic process of radiometric facet 
extraction in the various available images.
