Next time you drop by our Philadelphia offices to say hi, don't be surprised to find us wearing mustaches, trench coats,  and conversing with our good friend Dr. Watson.  For the past several months we've been sleuthing, exploring, and solving spatial mysteries.  We've developed new ways to search Japanese Gardens, have traversed the entire Philadelphia map to determine the most 'walkable' neighborhoods in the city, and have added heat map 'hunch' visualizations to our HunchLab software.   Our newly exercised sleuthing skills enabled us to find ourselves among the ranks of the 2009  Inc. Magazine 500|5000 list of the nation's fastest growing companies!  Welcome to another edition of the Azavea Journal.
