CRTI Data
ChicagoRTI.org
Urban forestry data
Chicago Region Trees Initiative
 In a period of rapid data expansion
 Many cities have:
• Land cover
• Inventories
• Surface temperature
• Socioeconomic, traffic or other
related data
ChicagoRTI.org
Urban forestry data
Chicago Region Trees Initiative
 Which data has CRTI utilized
 How did we collect it
 What did we learn from it

Z = (Value - average value)
standard deviation
Priority municipalities
 Low canopy
 High impervious
surfaces
 High vulnerable
populations
 High surface
temperature
Priority plantings
Chicago Region Trees Initiative
 Layers vary by stakeholder and area
 Need to communicate with stakeholders
to make priority maps that are relevant
