GIS, GIScience, and Spatial Data: An American Perspective Michael F. Goodchild University of California, Santa Barbara Walton Fellow, NCG
Uptake of GIS n What’s in a name? –geospatial –facilities management –land information systems n Uptake in all areas that deal with the surface of the Earth n 3D GIS –mining, geophysics –atmospheric science
Why GIS? n Management, inventory, maintenance –in any domain where location is important n Implementing policy –general principles applied in local context –database = local conditions –procedures, algorithms = general principles –simulating outcomes, what-if scenarios n Evaluating policy –mapping outcomes –identifying areas for intervention
Simulations n 1.8 vehicles per driveway n Driver behavior influenced by: –lane width –slope –view distances –traffic control mechanisms –information feedback –driver aggressiveness n 770 homes –clearing times > 30 minutes 2D clip 3D clip
Policy implications n Addition of new outlets n Better deployment of traffic control resources n Understanding the risk n Reduce cars used per household n Problems of shut-ins, elderly, latch-key kids
New technologies n Google Maps n Google Earth n Published APIs n Abundant data n A simple user interface
Animations n http://i.beatthetraffic.com/beatthetraffic3 d2.mpg http://i.beatthetraffic.com/beatthetraffic3 d2.mpg n Bedwell hike Bedwell hike n Alan Glennon’s geo/vantage Alan Glennon’s geo/vantage
New application domains n Public health –health service delivery location analysis –epidemiology cluster detection morbidity, mortality –data management data modeling –GIS in the GP’s office
A 5-stage model 1. Specify 2. Search 3. Assess 4. Retrieve 5. Open
A data model for disaster management n A prepared template n Rapidly populated –using prepared routines n Prepared analysis functions n Up and running within minutes
Computing in the presence of the subject matter n U = S –or S = U 1 through U n n Managing the disaster on the spot n Collaborative technologies n Augmented not virtual reality n Mobile, ubiquitous GIS –location-based services
The technologies of U = S n Portable, wearable devices –user interfaces n Positioning –the device knows where it is n Wireless communication n The Spatial Web –everything knows where it is –GPS, RFID, etc.
Geographic information science n The science behind the systems n Research that will improve future GIS n www.ucgis.org
Current GIScience topics n Extending GIS representation –3D, time, uncertainty n Extending GIS analysis –simulation modeling –data mining –visualization n Spatial data infrastructures –standards –geoportals
