ABSTRACT 
In spite of its high spatial resolution, HRV-SPOT images present some constraints for detailed intra urban 
and rural object discrimination and mapping. In this paper visual interpretation of HRV-SPOT images 
assisted by image processing was performed, aiming the analysis of intra urban street patterns, industrial and 
other large buildings, bridges and municipal roads. For this purpose, digital images were processed using 
spatial filtering and multisensor data integration techniques. They were displayed in full resolution. The 
results showed that, apart from some minor constraints that still remained, it was possible to map the objects 
of interest with higher precision and detail than using only analogical data.
