ACKNOWLEDGEMENT 
The project was funded by the US National Science Foundation 
(NSF) under contract number NSF 0131893. We would like to 
thank the project administrators at the City and County of 
Denver for granting permission to use their data. We especially 
thank Wolfgang Schickler at Analytical Surveying Inc. for their 
kind helps with the delivery and checking of the aerial images 
and digital surface model of downtown Colorado, CO.
