7. CONCLUSIONS
In this project, the images that have been orthorectified are spot
images, with spatial analysis 10m the panchromatic and 20m
the multispectral. The problem during the orthorectification was
the exact location of the control points in the images due to
their low analysis. Finally the resolution of the panchromatic
orthoimage is 8,9m and of the multispectral is 4,9m.
The synthetic image maintains the spectral and spatial
characteristics of the initial orthoimages, as the statistical tests
demonstrate.
As for the classification, the statistic tests that were done led to
very satisfactory results, 83,64% for the urban area and 81,48%
for the hilly area.
The results of visualization give one very realistic
representation of the anaglyph, especially for the hilly area
because the urban area has smooth anaglyph. The elevation
differences are clearly attributed and shown, by the
visualization of the DTM and the 3D flight-video over the area
of interest.
