In this case, a scanning algorithm to identify buildings contours and rooftop would do the trick quite accurately. The rest is integrating the Google sun tool and matching the elevation data to any map provider to get addresses… I know it’s doable. I just don’t have the technical capabilities to do it. Again, this is my non-expert opinion and there might be some technical or other limitations that I am not aware of. Hence my reach out.</div><div><br></div><div>Kindest regards,</div><div>Sid</div></div><div><br></div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Calibri; font-size:11pt; text-align:left; color:black; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM: 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; BORDER-RIGHT: medium none; PADDING-TOP: 3pt"><span style="font-weight:bold">From: </span> <<a href="mailto:b.j.kobben@utwente.nl">b.j.kobben@utwente.nl</a>><br><span style="font-weight:bold">Date: </span> Saturday, August 2, 2014 at 4:32 AM<br><span style="font-weight:bold">To: </span> "S.A.
