Geodata Assistant For First Responders

  1. 1. Geo Tools for First Responders R i c h a r d W e l t yWednesday, March 27, 13 1
  2. 2. Some Kinds of Geo Data Accurate GPS Maps Hydrant locations and capacities Building Footprints Chemicals at potential HazMat sitesWednesday, March 27, 13 2
  3. 3. How to Deliver The data is often already in existence Usually controlled by County GIS departments Often unwieldy in the field, or unavailable One Capital District FD has used rolodexes for hydrant data in the trucksWednesday, March 27, 13 3
  4. 4. Tablets Change THingsWednesday, March 27, 13 4
  5. 5. OpenStreetMap Changes Things Project to build a free digital map of the world Free in a difference sense than Google Maps or other online maps A “Wiki” project, crowdsourcingWednesday, March 27, 13 5
  6. 6. Hydrant MapWednesday, March 27, 13 6
  7. 7. Building FootprintsWednesday, March 27, 13 7
  8. 8. Tablet Features Good GPS Maps & Software Lots of memory for data Can preload data - don’t require Cell Service Affordable commoditiesWednesday, March 27, 13 8
  9. 9. GPS Issues First Responders don’t necessarily trust GPS Anecdotes about bad addressing Obvious problems with the street grid Updates in commercial GPS not timelyWednesday, March 27, 13 9
  10. 10. Tiger TIGER is a Census Bureau map database Public Domain All digital maps of the US started with a copy of TIGER (both online and GPS maps) TIGER is erratic, better some places than others OpenStreetMap in the US started with a copy of TIGER from 2005Wednesday, March 27, 13 10
  11. 11. Typical Tiger Issues Incorrect Road Names Bad Topology - “Not Hooked Up Right” Paper Streets Missing one way & access restriction information Out of date, missing new developmentsWednesday, March 27, 13 11
  12. 12. Street Grids in Old Cities Cortland Street Not Cortland StreetWednesday, March 27, 13 12
  13. 13. We can do better GPS maps don’t have to suck Enhanced 911 data for street addresses OSM crowd sourcing for completeness, currency, TIGER fix up Give control to the users of the dataWednesday, March 27, 13 13
  14. 14. Pilot Project Proposed Pilot - City Department or group of Volunteer Fire Departments Enhanced 911 address data owner - County GIS Department, other government agency Potential for grants to help fund pilotWednesday, March 27, 13 14
  15. 15. Proposed Delivery Android Tablet (e.g., Nexus 7 or Nexus 10) WiFi only (no cell) 32G OsmAnd GPS software Data in OpenStreetMapWednesday, March 27, 13 15
  16. 16. Advantages of Approach Commodity Hardware (32G Nexus 7 is $250 locally) OsmAnd is open source, already supports most needs OpenStreetMap provides Database No major IT infrastructure requirementsWednesday, March 27, 13 16
  17. 17. Department Involvement Need a desktop or laptop to build maps. Mac vs PC not important Need to train a few department staff in the maintenance of the system Figure out who the map geeks are and train themWednesday, March 27, 13 17
  18. 18. Measure Success Response times How good is current response time data? How much is enough to be valid Perception of users - importance vs. statistical measuresWednesday, March 27, 13 18
  19. 19. Open Issues Need to complete TIGER review in pilot area Need to import Enhanced 911 data into OSM Import Building footprints where available Need to improve US address handling in OsmAndWednesday, March 27, 13 19
  20. 20. Addresses & Routes Need to review a large enough group of randomly selected addresses for accuracy Before pilot deployment, spend time rerunning prior calls to see what routes are selected and whether the GPS really gets us to the right placeWednesday, March 27, 13 20
  21. 21. Policy, Vehicle Classes Policy on overriding One Way, Turn Restrictions Do we need different maps for different classes of emergency vehicles?Wednesday, March 27, 13 21
  22. 22. Hydrant Enhancements Include capacity (main diameter or AWWA classification) in database Display hydrants in different colors depending on capacity, e.g. green for 12” main, blue for AWWA class AA Display will be visible in GPS software to Firefighters as they travel to sceneWednesday, March 27, 13 22
  23. 23. Data Integrity Vandalism & mistakes (happens with wiki projects) Monitor changes to map (Changemonger) Only extract new GPS maps after validating changes Not a burden if you just stay on top of thingsWednesday, March 27, 13 23
  24. 24. Indemnification OSM and its volunteers do not have resources to fight a lawsuit How do we protect them in a modern, lawsuit prone environment?Wednesday, March 27, 13 24
