  • Commerce, e.g. Retail Analysis
  • Sample Global Questions from Earth Science
  • How is the global Earth system changing
  • What are the primary forcing of the Earth system
  • How does the Earth system respond to natural and
    human included changes
  • What are the consequences of changes in the Earth
    system for human civilization
  • How well can we predict future changes in the
    Earth system

Example of Application Domains
  • Sample Local Questions from Epidemiology
  • Whats overall pattern of colorectal cancer
  • Is there clustering of high colorectal cancer
    incidence anywhere in the study area
  • Where is colorectal cancer risk significantly
  • Where are zones of rapid change in colorectal
    cancer incidence

  • Evacuation Route Planning

Spatial Statistics Hotspots
  • The 1854 Asiatic Cholera in London

Academics GIS across Disciplines
Future of GIS Related Work
  • Steven Reader
  • Has not progressed beyond mapping, querying,
    spatial data inventory
  • Potential analytical power of technology to help
    solve complex societal and environmental problems
    has yet to be realized
  • Ron Briggs
  • future (e.g. traffic when I get there)
  • UAVs
  • K. Clark (Textbook on GIS)
  • Impact of computing trends,
  • Social issues geo-privacy,
  • Dobson (1983)
  • Automated geography

Future Prediction Vs. Vision
  • Predictions
  • 640K ought to be enough for anybody.
  • I think there is a world market for may be five
  • Everything that can be invented has been
  • People
  • Bill Gates, Chairman, Microsoft, 1981,
  • Thomas Watson, Chairman, IBM, 1943
  • Charles Duell, US Office of Patents, 1899.
  • Hard to predict future
  • despite tools like induction, deduction
  • Stochastic nature of natural and social processes
  • Why engage in futurology ?

Visions are important!
  • If you do not shape the future, someone else
  • Tim Phillips
  • many are short of really big ideas focus on
    immediately (day to quarter) issues, sometimes
    they forget that they got to be around in 10, 20,
    or 30 years.
  • The futurologists are not trying to make them
    happen, they are just considering the
    implications of them happening.
  • GIS Implicatons of Societal Needs
  • GIS Implications of Disrupting technologies and
    basic research

Societal Needs and Implications for GIS
  • Is G.I.Science relevant to Global Challenges ?
  • Next Decade Global Challenges World Fed. Of
    United Nations Asso.
  • Sustainable development for all
  • Clean water
  • Balance population and population growth
  • Policy making more sensitive to global long-term
  • Make information and communication technologies
    work for all
  • Reduce threat of new and reemerging diseases
  • Shared values and security strategies to reduce
    conflict, terrorism, WMD
  • Stop transnational organized crime networks
  • Meeting growing energy demands safely and
  • (6 more)
  • What are the implications for GIS ? Ex. Energy
  • Shortest path ? Fuel efficient routes, e.g.
    UPS/DHL reduce left tuens
  • Vehicle fuel efficiency vs. luxury
  • control increase A/C airflow on sunny side

Technology Evolution and Implication for GIS
  • Time
  • Continuous time, e.g. vehicle tracks, events.
  • Slow update rate - Rarely real-time
  • Future Limited Predictive capabilities,
    Spatio-temporal statistics
  • Network
  • Statistics on Spatial Networks (e.g.road maps)

Geospatial Intelligence
Predictive View
Recorded View
Situational Awareness
Knowledge Discovery

(correlating signatures to predict events)

How many SAMS have moved more than 25 miles today?
What other events could occur with this pattern?
Problem Complexity
Data Base Maintenance
Predictive Analysis

Computing Trends and GIS Implications
  • 2020 Information Technology M. Gough, CEO (NCC)
  • PC Terflop CPU, Terabyte memory, Peta-byte
  • Ubiquitous computing and sensing
  • Spatial Sensors location orientation posture
  • Web 2.0, social networking, virtual life
  • Q? What is the impact on G.I.Sc. ?
  • Point and ask in real world (w/ laser pointer ?)
  • Increase computing capacity
  • Scale up spatial models (e.g. spatial
    autoregression, agent based)
  • Wider use of LIDAR, Global-Hawk UAVs
  • Will web 2.0 change importance of location ?
  • Impact on clustering of brainpower and wealth

Technology Trends Beyond Computing
  • Future Shock Livewire, Summer 2007, AI
  • Robotics
  • Mind-controlled interfaces
  • Personal networking
  • Smart Building
  • Smart Fabric
  • Nano
  • Bio-technology
  • Semantic Web
  • Q? What is the impact on G.I.Sc. ?
  • Bio-technology
  • Neurosurgery how to locate safe pathways to
    target in brain ?
  • Autonomous robots (.g. DARPA grand challenge)
  • Navigation on dessert terrain gt real-time GIS

Another Real-Time Application Homeland Defense

If you do not shape the future, someone else will!
  • What do we want G. I. Sc. to be in 2015 ?
  • What are barriers to achieving our 2015 vision?
  • What may we do to make 2015 vision more likely ?
  • Why coordinate GIS academic research and business

What do we want G. I. Sc. To be in 2015 ?
  • Government An essential part of governance
  • Juliani effect post 9/11
  • Agencies like NGA, Roles like GIO
  • Spatial Budget processes
  • Ex. Gas tax ? Road user charges system
  • Predict Police budget for new developments
  • Business
  • Horizontal Many Fortune 500 leader considers
    GIS essential!
  • Marketing, Logistics, Facility location ?
  • Spatial pricing models for floor cleaning
    machines, ...
  • Academia, University
  • Discipline (department) vs.Interdisciplinary
    (center, institute) ?
  • Research Enterprise Science grand challenges

What are barriers to achieving our 2015 vision?
  • What would someone do to stall a 2015 vision?
  • Academic Discipline (department) or
    Interdisciplinary (center)
  • Is it a critical need for the university, state,
    nation and society?
  • Are there deep intellectual issues ? (Is it only
    pretty pictures?)
  • Is it a passing fad ?
  • Will the unit be financially self-sufficient ?
  • Tuition service courses, major
  • Research grants
  • Resource constraints space, faculty lines,
  • Government
  • Business

What may we do to make 2015 vision more likely?
  • Work together
  • On hard problems of societal importance
  • Communicate societal benefits to decision makers
  • Academia needs support of Business and Government
    to establish need for new disciplines,
    departments, centers, institutions
  • And vice versa
  • Goodchild, Haining and 12 others (IJGIS, 1992)
  • if GIS as science is to continue to garner
    academic recognition and funding, be able to
    demonstrate the important and usefulness of its
    research to GIS applications so that wider GIS
    industry becomes an advocate and financial

Personal view on interesting research?
  • Personal view on interesting research
  • Problem, why is it important? Why is it
  • Solution / Approach, Is it novel? Is it better
    than state of the art?
  • Role of industry (beyond resources)
  • Source of problems of societal interest
  • May help assess state of the art in industry
  • Contribute new ideas to solution and approach
  • Expose entrenched academic assumptions

Complicated Hotspots
  • Complication Dimensions
  • Spatial Networks
  • Time
  • Challenges Trade-off b/w
  • Semantic richness and
  • Scalable algorithms

Example Basic Research Needs
  • Location Prediction and
  • Spatial interest measure e.g., avg, dist(actual,
