16. Santa Fe Escarpment Re-Mapping Barriers to Overcome 1. Long distance client 2. Iterative process 3. Need for end user validation 4. Requires unique web-based analytical capabilities

17. Santa Fe Escarpment Re-Mapping Requirements 1. Accurate: Old zone had misaligned polygons 2. Defensible: Analytical foundation; acceptable methodology 3. Transparent: Access to data layers; validation tools 4. Flexible: Needs to adapt to community values and political will

18. Accuracy Issues Polygons don’t follow ridgelines

19. Defensibility Why are these mapped ... but not this one?

20. Transparency – No Favorites Client needed the ability to review data layers and validate analytical results

21. Flexibility – User Generated Content This ... ...This? or Final results must reflect community values and political will

22. Browser-Based Spatial Analysis Tools 1. Reclassification - “Slicer and Dicer” 2. Sight Lines – Visibility and above-skyline visibility “ on the fly” 3. Cross Section – Elevation profiles for sight lines 4. 3D – Render from sight line or other vantage points

23. Reclassification Tool - “Slicing and Dicing”
