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 collaborative GIS software with a simplified user interface

WISE Prototype Data
• GPS location• Nutrients
Nitrite (NO2), Nitrate (NO3), Ammonia & pH
• Macro-Invertebrates Some species more/less resistant to pollutants
• Sediments Turbidity blocks sunlight

What is Next? WISE Prototype
• Short-term: Exploring feasibility & functionality
NSF Goal• Long-term: Educators need a GIS app
builder
University of Calgary - September 13, 2011
Component-based customizable collaborative GIS software with a simplified user interface
17
What is Next?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)

GIS Concepts 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
