1. Geographic Information Systems (GIS) Group Wingyan Chung, SCU OMIS Albert Esterline, NCAT CS Greg Ferrara, NCSU Ron Hughes, NCSU Lawrence Kiage, Georgia State U Richard Plant, UC Davis Group Session 3 Report, Sat. 8:00-9:00 am

2. 2 GIS Concepts Effects of Map Scale Data capture Database management and data schema/structure Data quality Programming Visualization Data transformation Pattern analysis Display / delivery / communication Network analysis Geospatial analysis

3. 3 Terminology Difference Same terms but different meaning Data structure Database schema Scale -- spatial scale vs. performance Topology (e.g., point) Different terms but same/close meaning Pattern analysis vs. data mining

4. 4 Computing/IT as a tool Programming.NET, Visual Basic, Java, Javascript programming GIS visualization software Data management MS Access database management SQL queries Pattern analysis (trends) Simulation Web technologies (not widely taught now) XML family, Web services, protocols

5. 5 Computing/IT as a concept Data management and analysis Data modeling, knowledge representation Database design and development Data mining concepts Programming skills From a user to a developer (SE cycle) Programming skills and patterns User interface design concepts Simulation Process modeling and visual representation

6. 6 Ideal Implementation (1) Using SE methodology at advanced GIS projects May need students from different disciplines for a common exciting goal Problem-based learning - use cool X to teach uncool Y A capstone course, example project: Precipitation estimates on different locations Get estimates of nearest weather stations => need computational geometry concept and algorithm design Finding Malaria hotspots / Socially-responsible GIS apps. Process modeling Creating traffic model using Petri-net Multi-agent simulation (e.g., forest fire modeling) Modeling an area’s soil erodibility, habitability

7. 7 Ideal Implementation (2) Social computing in the Introduction to GIS course (also in intro CS course) Location-aware computing, GPS apps, mash-up, Google map Privacy, IP, ethics Accessibility of location information, open-source GIS software (* GIS typically is not a major, but a part of geography or something else (exception))exception
