  3. GEOGRAPHIC INFORMATION SUPPORT TEAM ITOS and the GIST Repository Data and Services Portal https://gist.itos.uga.edu GIST Portal

  4. ITOS and the GIST Repository • Data Processing and Metadata Services • Metadata Search Engine • Downloadable WAF • Live Mapping Services (thin and thick clients) – Global Map Series • FTP • Membership Directory • Document Library GIST Portal

  5. Data Creation and Crowdsourcing iMMAP/WFP/GISCorps

  6. Data Modelling ETL Models

  7. Custom Application Development UNHCR/GE

  8. Repository Holdings: Static Maps Static Map Holdings

  9. Repository Holdings: Vector Sets Static Map Holdings

  10. Two problems • Find point location information from descriptive strings • Find polygons for disaster areas: admin boundaries or footprints Objective

  11. Find location information from descriptive strings Existing Structure

  12. First, parse out locations but maintain the unique disaster identifier Structure

  13. Locations with unique disaster ID Structure

  14. Gazeteer Services • Input string into Gazetter (Directories) service and return the Lat/Long (as a starting point). • Possible services • Google Earth (easiest parsing mechanism) • Bing Maps (used to be Microsoft Virtual Earth, runs on old ESRI World Gaz. Service) • Taggeo.com • Geonames.org • Maplandia • http://alexandria.ucsb.edu/gazetteer/ • http://www.columbiagazetteer.org Methods

  15. Batch Services • There is a batch service for address geocoding in Google Earth for some countries • I have not seen a batch service for a gazeteer lookup or fly to search – may need to write a custom application (or do manually) Methods

  16. Bing GZ Service Methods

  17. Bing GZ Service Methods

  18. Result, post-geocoding • After geocoding you will have a cluster of points per event, you can • export to use in an image archive search engine (footprinting) • create a minimum bounding polygon or • select within themes to highlight admin boundaries. Methods

  19. Structure Summary (Nested Polygons) Structure

  20. Structure Summary (Attribution) Structure

  21. Level 0 (Country Level) Existing

  22. Level 0 – 20 Gaul Countries Not in GIST Database Missing

  23. Level 1 Missing

  24. Level 2 This list of 37 countries come from the GAUL website; we assume that Level 2 boundaries exist for these countries. GAUL has level 2 data for all other countries which have level 2 divisions. Missing

  25. Level 2 – 106 Missing from GM, 37 Missing from GAUL* Missing

  26. Level 2 – 37 Missing from both GM and GAUL Missing

  27. Level 3 GM has 16 level 3 datasets that GAUL does not have GAUL has 7 level 3 datasets that GM does not have Existing

  28. Level 3 –GM and GAUL 16 level 3 datasets in GM missing from GAUL 7 level 3 datasets in GAUL missing from GM Existing

  29. Levels 4 and 5 GM has 2 level 4 datasets that GAUL does not have Both GM and GAUL have Kenya as the only country represented with level 5 divisions Existing

  30. Level 4 – 2 level 4 datasets in GM missing from GAUL Existing

  31. Settlements and Urban Areas Existing
