###Matt Jahn

  • how accurate is accurate is mobile location on street?
  • how accurate is mobile location indoors?
  • Matt works for an indoor location company that’s tested a lot of different indoor location solutions
  • many solutions rely on in phone sensors, works best when paired with input from wireless networks in building
  • coolest tech: phones utilizes magnetic field map of building to pinpoint location
  • major barrier to innovation caused by hardware and software solutions that apply to small part of ecosystem

###Matt Veenstra

  • works on projects in downtown Seattle that reference the Denny Regrade (removal of hill that used to be just east of Belltown)
  • very few maps exist from that era
  • data used by existing projects is not free
  • geo-referenced historical map of Seattle from 1890s

  • loaded the data into Google Earth and it looks amazing, office buildings half submerged in glacial till
