Houston land cover: 1997-2016
Hakkenberg et al. 2017 2016 1997
Goal: •  Characterize spatio-temporal dynamics of land cover change in the greater Houston area between 1997-2016.
Goal: • Characterize spatio-temporal dynamics of land cover change in the greater Houston area between 1997-2016. • Thematic resolution: 10 classes
“How” is Houston growing? o where are farms and forests being converted to urban areas? o where are urban areas growing denser? o how fast are these changes occurring?
Kinder UDP Land Cover Products: • Validated annual classified maps from 1997-2016 at a 30m resolution • Validated change maps/time series • Spatially explicit uncertainty estimates
A novel product: • No land cover classification exists at this level of spatio-temporal detail – Houston is the first in the US! • Unique algorithm just received ~1M NASA grant • Novel technologies give rise to a new class of interdisciplinary questions
Curating Built Environment Datasets Kelsey Walker, Kinder Institute for Urban Research
Built Environment Datasets Publicly available data produced by local governments Two varieties of curation Distilling Assembling
Distilling Harris County Appraisal District Data Recent construction Demolition permits New building permits
Distilling Harris County Appraisal District Data Kinder Institute report and interactive map HoustonInFlux.com Collaborations: National Trust for Historic Preservation: Character Score Reinvestment Fund: Market Value Analysis
Assembling Parks Data Overlapping jurisdictions: City of Houston Harris County Houston Independent School District (SPARK Parks) State of Texas Smaller cities
CITY OF HOUSTON
HARRIS COUNTY
HOUSTON INDEPENDENT SCHOOL DISTRICT
Shining a Light on Crime: Streetlights and Crime in Houston, TX Heather A. O’Connell Julia Schedler
Brighter = Safer? Do more streetlights mean fewer reported crimes?
Streetlight Density
All Reported Crimes
All Reported Crimes
So much to learn… Crime patterns – do they change over time? Health and the local environment – are crime and streetlight density related to physical activity?
EMS Data – What can we learn? Loren Raun and Kathy Ensor
EMS + Fire Response • Cardiac arrest first responders • Augmenting the EMS network with response by firemen decreases the overall emergency response time.
Saving lives • The expedited response time by firemen increases the return of spontaneous circulation of cardiac arrest patients. • Blue is good!
EMS Data + Air Quality • GOAL: Reduce frequency of childhood asthma EMS calls by better managing care • Collaboration with City of Houston and HISD • Identified the air quality mixture that produces a measurable increase in the frequency of EMS calls for asthma. • Developed an air quality alert network and readiness plan for actionable days.
Understanding Air Pollution and Asthma NO2 and Ozone matter
Reducing Asthma emergencies • Map of EMS ambulancetreated asthma attack rate per 100,000 (2004 – 2011) • Eleven community centers ranked by rate of EMS ambulance-treated asthma attack • 12 out of 248 schools do not have nurses, some located in the high rate region

UDP Users • The UDP Oversight Committee reviews requests for access to UDP resources including software. • Level of access provided will meet all federal, state, county and city regulatory requirements. • Once request is granted, users are provided access to the data directories housing the required data.
Explore what’s available • A public link will be available for prospective users to explore what data sources are available through the UDP. • Some public data curated by our team will be publicly available for use with citation by others outside of Rice. • Census / ACS / HCAD • As much as we can…
