The document discusses several GIS mapping projects and the barriers faced in each, as well as the solutions and requirements. It describes projects mapping security zones in Los Angeles and San Francisco, youth organizations for UN-Habitat, and the Zayo Group's network infrastructure. Common barriers included cost, terms of service, incompatible plugins, and limited functionality. Solutions leveraged open source software, APIs, and custom development to create accurate, extensible, and transparent maps while overcoming barriers like international audiences, iterative processes, and unique analytical needs.

1. GIS on the Web: Breaking Down Barriers Ed Russell - President, Computer Terrain Mapping Michael Hinke – Principal Consultant, Decision Support Resources

2. Barriers Cost Terms of Service Incompatible Plug-ins Limited Analytical Functionality Cookie-cutter look of dominant software

3. Mapping Security Zones in Los Angeles and San Francisco Barriers: Client inexperience Data collection Data QA/QC Satellite Coverage Small budge t

4. Mapping Security Zones in Los Angeles and San Francisco Requirements: Open: results available on the WWW, Accurate: spatially and temporally, Extensible: website is set-up to let people add data from other cities, Defensible: methods must withstand rigor of peer review

5. Mapping Security Zones in Los Angeles and San Francisco The Solution: 3G iPhone, PostgreSQL/PostGIS, Mapserver, XifPix, Google Picasa, in-house software development

8. Mapping Youth-led Development Organizations for UN-Habitat Barriers: International audience of decision-makers Plug-ins Data QA/QC Terms of Service Budget

9. Mapping Youth-led Development Organizations for UN-Habitat Requirements: Open: results available to decision-makers (wherever they may be), Accurate: spatially, Extensible: website is set-up to let project administrators add and QA/QC data.

11. Mapping Youth-led Development Organizations for UN-Habitat Remaining Issue: Extensibility The website - as it stands now - is not set-up to allow project administrators to: Add data Edit data Solution: Drupal

12. Zayo Group – Mapping Network Infrastructure Barriers: Users located all over the United States

13. Zayo Group – Mapping Network Infrastructure Requirements: Open: maps available to anyone Accurate: spatially (roughly) and temporally Extensible: website is set-up to be extended to other business groups and to allow a variety of people to update the kml

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”

24. Slice and Dice – Part 2

25. Sight Line Tool – Viewsheds and Skylines

26. Cross Section Tool Elevation profile from selected sight line

27. 3D Visualization – Browser Based

28. Summary of Solutions Leveraging Open Source software, APIs, and EdWare Server-side analysis – reduces reliance on plug-ins/client-side technology Rolling our own to meet the needs of our clients, the results: User generated content Custom look and feel
