What we know about spatial reasoning … and maps
• Generally - a poorly developed skill,
• More engaging if well known area or familiar (home)
• Oblique (airplane) view closer to most people’s prior experience vs. nadir view
• Map view requires prior experience with symbology
• Contours hard to interpret
• Colors/shading can help but …
• Artificial band combinations can be confusing

Concept vs. Reality

Watershed Processes:Enduring Understandings
1. Definition & representation (maps & scale)
2. Basics: WS components and processes
3. Change: WS’s change over time (natural, anthropogenic)
4. Function: WS’s are complex systems
5. Management: WS management is complex
6. Issues: familiarity with SW watershed issues
