The attempt of integration of DTM that present different The t 
characteristics of grid spacing or extension requires automated provi 
procedures that are still under development. In fact, before techn 
integrating data, it is necessary to check and remove the offset deteri 
among the different DTM in comparison with reference data. Maxi 
Tests of orthorectification performed with the two DTM showed chara 
an improvement in metric accuracy of the orthoimage, but not majot 
so significant as it should be expected from the use of a more from 
detailed DTM. Probably it has to be due to problem with GPS succe 
signal reception that compromised in such cases a good LIDAR effect 
survey (and, therefore, the generation of DTM). obser 
The use of intensity data from LIDAR survey allowed a better data 
interpretation of the territory, above all in those areas that in the 
satellite images are covered by shadows and clouds. A further 
work will be directed to perform a real automated integration 
and fusion of lidar intensity values and satellite images in order 
to make a complete and detailed description of the study area. Satell
