==TIF Analysis==
Using Burlington, VT at the elbow, we plotted the hulls and TIFs. This is in WorkingMapV2.mxd. Some potential measures include:
*Overlapping Hull and TIF area
*Fraction of Hull area covered by TIFs
*Non-overlapping Hull and TIF area
*Adjacent Hull and TIF area (and non-adjacent) -- expand out hull area to allow for new inclusion without affecting density
*Count or Fraction of locations in TIF areas
The data needs to be reprocessed to be in the format:
place statecode year tifname geog
Or at least start-year and end-year...
Plotting Chicago (-87.7, 41.9) in 2017 using chosenlayer (layer=92) reveals some insights. There aren't any TIFs in the city core, but there are lots of startups. And conversely likewise, there are lots of TIFs covering suburbs that have few if any startups. There are, however, some areas of overlap. And some possible pattern of startups appearing exactly where TIFs aren't -- In a few cases (one notable), the startups are essentially surrounded.
And Houston in 2017, using layer=20 (as no chosen exists and 20 has max nohull at 7), it seems that there is little overlap between hulls and TIRZ but considerable overlap between Rice's "Innovation Corridor". The Sears Building, at (29.7255505,-95.3887225) [https://www.google.com/maps/place/Sears/@29.7255505,-95.3887225,14.79z/data=!4m8!1m2!2m1!1ssears+building+near+Houston,+TX!3m4!1s0x0:0xedfec0ea6b614672!8m2!3d29.7342719!4d-95.3822708] and Houston Exponential's building at (29.7521572,-95.3778919) [https://www.google.com/maps/place/Houston+Exponential/@29.7521572,-95.3778919,17z/data=!4m12!1m6!3m5!1s0x8640bf41ab209b51:0x4b09faaacfaffa81!2sHouston+Exponential!8m2!3d29.7521572!4d-95.3757032!3m4!1s0x8640bf41ab209b51:0x4b09faaacfaffa81!8m2!3d29.7521572!4d-95.3757032] are both in the Midtown TIF, albeit at opposite ends! There are other TIFs impacted by Rice's proposal too. The East Downtown, Market Square, Montrose, and at least three others all intersect the "planned" innovation corridor.
