Geographic Information Systems (GIS) @ GIS at UCSD Here to help you explore our world
GIS at UCSD what it is and what it means to you Tracey Hughes UCSD GIS Coordinator 2006 Image from Google Earth
An outline
A little about me GIS Coordinator Information Professional Librarian Spatial analyst AICP Planner
What GIS is Geographic Information System Implemented with software tools Spatial mindset Spatial analysis Visualization in 2D, 3D, or 4D
Representation of the real world Layers with attributes Attributes can be almost anything Two main data types Raster Vector Image from ESRI
Three views of GIS Database Map Model
The GIS Process Ask a question Obtain necessary data Determine best method of analysis Temporal Spatial Attribute Analyze Present results
How GIS relates to you Visualize, explore and shape environments Built environments Urban & regional planning Economic & community development Architecture Culture Natural environments Science Environmental justice Earth Atmosphere Ocean Social environments Education Social equity Policy Image from http://oceanexplorer.noaa.gov/technolog y/tools/mapping/mapping.html
The questions you answer with GIS Measurement How far are sewage outflows from protected habitats? Location Is there a spatial relationship between cultural and marine resources? Condition Examine land areas which have appropriate transportation and emergency facilities for ecotourism. Proximity Identify census tracts within 1 mile of a floodplain. Pattern Do tagged shark populations tend to be observed in deeper or more shallow waters? Visualization in 2D, 3D (height/altitude/depth), 4D (3D+time)
Communicate [GIS] incorporates the geographic visualization of databases, metadata and history, and has become a fundamental communication modality to government, academic and nonprofit agencies. --Rosemary McKeon, UCSD Visual Arts Graduate Accessed on 10/18/06 at http://jupiter.ucsd.edu/%7erose/teaching.htm.
How GIS relates to you Sell your position as the saying goes, a picture is worth a thousand words!
GIS in action London Cholera Epidemic of 1854 Image from http://www.ph.ucla.edu/epi/snow/watermap1856/watermap_1856intro.html Map on following page from http://www.crissycorkboard.org/gis_class/london.htm
A spatial issue? Each dot represents one death from cholera. 500 people died in the epidemic, caused by a contaminated well.
