6. CONCLUSION AND FUTURE WORK 
We have presented a method for the extraction of buildings 
from high-resolution LIDAR data in densely built-up areas. 
Preliminary results from a test site in the City of Vienna have 
shown the high potential of the method. Future work will not 
only include the implementation of the modules still missing, 
but also the assessment of quality parameters for the results. 
With respect to the building outlines, this can be accomplished 
by a comparison to existing GIS data. In addition, we will 
perform research work in order to improve the results of 
building extraction by additionally using digital aerial images 
for matching of roof edges with image edges.
