  6. GK12 Education • GIS is a major technology but… • …it is not for novice users • Like teachers • …it demands high-end hardware • Unlikely to be found in GK12 schools • Wish List Component-based customizable collaborativeGIS software with a simplified user interface University of Calgary - September 13, 2011

  7. WISE Prototype http://gk12.cnu.edu/ • Data • GPS location • Nutrients • Nitrite (NO2), Nitrate (NO3), Ammonia & pH • Macro-Invertebrates • Some species more/less resistant to pollutants • Sediments • Turbidity blocks sunlight University of Calgary - September 13, 2011

  8. WISE Prototype • Client/Server • Server hosts GIS software & data. • Clients use interface to add & access data. • Server • ArcGIS NN School CNU • Clients • Web browser & Adobe Flash NN School University of Calgary - September 13, 2011

  9. WISE Prototype • Data name name/initials name 1 School Teacher Student 1+ 1 * name, extent Site name, latitude, longitude 1 * GPS point 1 NO2,NO3,pH,ammonia,date * * * Sediment Macro Invertebrate Nutrient value, date deployed, date collected biotic index, date University of Calgary - September 13, 2011

  16. What is Next? • WISE Prototype • Short-term: Exploring feasibility & functionality • NSF Goal • Long-term: Educators need a GIS app builder Component-based customizable collaborativeGIS software with a simplified user interface University of Calgary - September 13, 2011

  17. What is Next? Component-based customizable collaborativeGIS software with a simplified user interface What do we mean by… • Component-based • Building-block functionality • Scalable & Robust • Customizable • User-defined composition • Collaborative • Distributed system: • Multiple locations • Multiple participants (+privileges) • Multiple devices • Simple GUI • Intuitive to use by novices (builders + users) • Easy to deploy & maintain (using limited resources) University of Calgary - September 13, 2011

  18. GIS Concepts APPENDIX • Geographic Information System • Software able to store, manipulate & display geographically referenced information (data identified by a location) University of Calgary - September 13, 2011

  19. GIS Concepts APPENDIX • Data Properties • Location • Attributes • Spatial relationships • Data Models • Vector: Point, Line, Polygon (area) • Raster: pixel pictures (satellite images) • Projections • Mercator, et al. (be consistent) • Query & Analyzing • Pulling information from a GIS • Overlaying & Buffering For more: Google: GIS tutorial University of Calgary - September 13, 2011
