Geo Tools for First Responders - SOTM US 2014 - Full Version

  1. 1. Geo Tools for First Responders Richard Welty SOTM-US 2014 1Sunday, April 13, 14
  2. 2. Relevant Types of Geo Data • Enhanced 911 Addressing for GPS • Hydrant data (location) • Hydrants on water systems (capacity) • Dry Hydrants (lift, seasonal issues) • Ponds, Streams • Landing Zones for Medical Evacuation • Hazmat • PrePlan data 2Sunday, April 13, 14
  3. 3. CAMEOfm • from the EPA • PC based • need a laptop in the field • lots of interesting capabilities for Hazmat in an aging format 3Sunday, April 13, 14
  4. 4. Alternatives • “Data Terminals” • Princeton Project • Active911.com • CAMEOfm • Others 4Sunday, April 13, 14
  5. 5. Existing Data Terminals • Fire Department terminals derived from long standing Police models • Many functions require radio link to Dispatch • GPS from commercial map data • Expensive 5Sunday, April 13, 14
  6. 6. iPad/iPhone apps • One from Princeton for iPad (student project) • Data in Cloud, needs Cell Service • Active911 - Commercial App • Started as messaging app • GPS capabilities from Google Maps 6Sunday, April 13, 14
  7. 7. How to Deliver • The data is usually already “somewhere” • County, City GIS departments • Often unwieldy • One Capital District department used a rolodex in each truck for hydrant data • Albany NY hydrant data on paper maps 7Sunday, April 13, 14
  8. 8. OpenStreetMap Changes Things • Project to build a free map of the world • Open Data project • A Wikipedia of maps, if you will 8Sunday, April 13, 14
  9. 9. Project Inception • Considering potential for Emergency Services Application since 2009 • Summer 2012 - realized the near term potential for a usable GPS map of Albany • Digital Maps of US have common problems • Urban Street grids have issues too 9Sunday, April 13, 14 Common problem: old TIGER
  10. 10. Street Grids in Old Cities Cortland Street Not Cortland Street 10Sunday, April 13, 14
  11. 11. Commercial GPS Issues • All digital maps of the US derived from Census Bureau TIGER data • Lots of errors (much better recently) • Commercial map vendors fix lots of errors, but not all of them 11Sunday, April 13, 14
  12. 12. Commercial GPS Issues • TIGER errors not fixed in less populated places • Long delays in updates • Release schedules typically quarterly • Limited motivation to deal with issues in less populated areas 12Sunday, April 13, 14 Rensselaer bridge over RR tracks
  13. 13. OSM GPS Maps • Potentially way better • Continuous updates • Apps usually offer opportunities for consumers to pull/build current maps • Wiki - Errors can be fixed by users 13Sunday, April 13, 14
  14. 14. OpenFireMap 14Sunday, April 13, 14
  15. 15. Geo Data Assistant • WiFi only Android Tablet (Nexus 7) • OsmAnd GPS application • Plugin to support Emergency response specific features • Additional data may come from elsewhere 15Sunday, April 13, 14
  16. 16. Advantages To Approach • Commodity Hardware • 32G Nexus 7 is $300 pretty much everywhere • OsmAnd is Open Source • OpenStreetMap for base database • No major IT infrastructure requirements 16Sunday, April 13, 14
  17. 17. Internet/Cell Access not a requirement • Poor to non-existent service in many rural areas • Good tablets have more than enough storage to support application & data 17Sunday, April 13, 14
  18. 18. Mutual Aid • Primary use case (at least initially) is Mutual Aid • Departments/Engine companies responding outside of their normal operational area • Firefighters experience many problems responding out of area 18Sunday, April 13, 14 addressing in large apartment complexes lack of knowledge about neighborhoods water system issues - private hydrants, no way to determine capacity of hydrants
  19. 19. Out of Area Response • Do not know neighborhoods • Do not know water system • Apartment Complexes • Private Hydrant systems 19Sunday, April 13, 14
  20. 20. Extreme Mutual Aid • 9/11 • Hurricane Sandy 20Sunday, April 13, 14
  21. 21. Hydrant Gallery 21Sunday, April 13, 14 dry barrel - discuss features Steamer vs hose connections color schemes contain no real information
  22. 22. Hydrant Gallery • Wet Barrel • West coast • UCLA colors 22Sunday, April 13, 14
  23. 23. Hydrant Gallery • Wynantskill, NY • AWWA color scheme • Blue Caps & Bonnet • Class AA Hydrant • > 1500 GPM 23Sunday, April 13, 14 capacity helpful, but you don’t know the capacity until you see the hydrant
  24. 24. AWWA Classification Class Flow (@ 20PSI) Cap & Bonnet Color AA More than 1500 GPM Blue A Between 1500 GPM and 1000 GPM Green B Between 1000 GPM and 500 GPM Yellow C Less than 500 GPM Red 24Sunday, April 13, 14 distinguish between static (head) pressure and pressure while operating hydrant
  25. 25. Capacity • Why is capacity important? • Big fire, need lots of capacity • Drawdown of water in main can damage appliances in residences (notably hot water heaters) • Risk of main collapse 25Sunday, April 13, 14
  26. 26. Hydrant Gallery • Bethlehem, NY • Green = large main • Orange = medium main • Red = small main 26Sunday, April 13, 14
  27. 27. Hydrant Gallery • Tag on Steamer connection instead of paint for flow capacity 27Sunday, April 13, 14 problem with painters
  28. 28. Hydrant Gallery 28Sunday, April 13, 14 no Steamer connection on left, only steamer connection on right
  29. 29. Snow • “If I have to dig one out of the snow it better be a good one” 29Sunday, April 13, 14
  30. 30. Out of Service • Not all Hydrants are operational 30Sunday, April 13, 14
  31. 31. Out of Service 31Sunday, April 13, 14 can’t see out of service condition until you see the hydrant
  32. 32. Out of service (But it’s a secret) • NYC “Stubby” hydrant • High pressure system operated from ca 1905 through 1979 • Stubby hydrants still around in NYC 32Sunday, April 13, 14 reference extreme mutual aid
  33. 33. Is this a hydrant? • Rural VFD, no pressurized water system • Lawn Ornament 33Sunday, April 13, 14
  34. 34. Hydrant Gallery 34Sunday, April 13, 14 Sources: ponds, lakes, streams seasonal issues, lift
  35. 35. Dry Hydrant, but... 35Sunday, April 13, 14 water source is higher than hydrant
  36. 36. Wrench Types 36Sunday, April 13, 14 also apparently triangular and conventional hex heads
  37. 37. Hydrant Display 37Sunday, April 13, 14 OsmAnd+ screenshot
  38. 38. Building Footprints 38Sunday, April 13, 14
  39. 39. Color Code extension 39Sunday, April 13, 14 color code for capacity Use case: observing hydrant capacity while riding in to the scene, stopping to start laying hose on the way in
  40. 40. OSM Tagging • Some current tags • emergency=fire_hydrant • fire_hydrant:type={pillar,pond,underground} • colour={red,yellow,green,blue,...} • diameter=12 inches 40Sunday, April 13, 14 pillar - used in Germany, correct in US usage but not common. not used in UK. diameter - main diameter pressure - in bar (head pressure?), not relevant to US operating practice pond - inappropriate conflation
  41. 41. Tagging Issue • fire_hydrant:type conflates physical type of hydrant and water source • pillar vs pond 41Sunday, April 13, 14
  42. 42. Tagging Issue • Add new tag • fire_hydrant:water_source={pond,stream,main} • evolve fire_hydrant:type values • retain pillar,underground • deprecate pond • add pipe, dry_barrel, wet_barrel 42Sunday, April 13, 14
  43. 43. Capacity Tags • Proposed, not currently official • fire_hydrant:capacity=700 GPM • fire_hydrant:class={AA,A,B,C} • fire_hydrant:water_source={main, pond,stream} • Capacity on streams? 43Sunday, April 13, 14 LPM for non-US jurisdictions
  44. 44. Additional Tags • More proposed tags • color:reflective={white,blue,yellow} • color:bonnet={red,blue,green,white,...} • color:cap={red,blue,green,orange,white} • color:cap=grey;yellow • in_service={yes,no} 44Sunday, April 13, 14
  45. 45. Examples emergency=fire_hydrant fire_hydrant:type=dry_barrel fire_hydrant:water_source=main colour=yellow colour:cap=blue colour:bonnet=blue emergency=fire_hydrant fire_hydrant:type=pipe fire_hydrant:water_source=pond colour=red colour:reflective=white 45Sunday, April 13, 14
  46. 46. Other Properties • Outlet sizes, threads • Wrench type and size • triangular, square, pentagonal, hexagonal 46Sunday, April 13, 14 • Orientation • Steamer valve perpendicular to curb vs 45 degree angle Orientation probably not that important
  47. 47. Dry Hydrant Tags • Dry hydrant conditions • weeds • low water levels (winter) • lift 47Sunday, April 13, 14
  48. 48. Landing Zones • Landing Zones (Med Evac) • current tags that are relevant • name • operator • need to characterize additional information 48Sunday, April 13, 14 don’t want to use the existing aviation tagging, as that is for general purpose landing facilities, not for emergency LZs
  49. 49. Hazmat Data • In the US, this actually information of public record • Probably not be appropriate in OSM • Candidate for private data store 49Sunday, April 13, 14
  50. 50. Hazmat Use Cases • Materials in building that’s on fire? • Materials in adjacent buildings • Plume direction/danger based on prevailing winds • CAMEOfm capability that may be easy to integrate • Potential interaction with GPS 50Sunday, April 13, 14
  51. 51. Other Considerations • Policy on overriding One Way, Turn Restrictions • Do we need different maps for different classes of emergency vehicles? 51Sunday, April 13, 14
  52. 52. Making It Happen • Find a department or group of departments that wants to spend grant money on a pilot • Need to control size, ambition of pilot 52Sunday, April 13, 14
  53. 53. Making It Happen • Need to complete TIGER review for pilot area • Import E911 addresses (and building footprints whenever available) • OsmAnd needs improvements to handling of US addresses • Test, Test, Test 53Sunday, April 13, 14
  54. 54. Test, Test, Test • Select random addresses and verify that you arrive at the right place via a sensible route • Replay actual calls from prior days • Simulate mutual aid by using prior calls from different stations 54Sunday, April 13, 14
  55. 55. Requirements for the Department • Desktop or laptop to extract and build maps. Mac vs PC not important • Need to train a few department staffers on the system • Figure out who the map geeks are and train them 55Sunday, April 13, 14
  56. 56. Private Data • May need to support data that is not appropriate for OSM • OsmAnd supports layers of data from elsewhere • May want to extend in plugin • May need to provide a low cost support service for departments 56Sunday, April 13, 14
  57. 57. Emergency Services Plugin • Add features to OsmAnd that aren’t needed for the general public • Special handling for POIs of interest to emergency responders • Hazmat support • popup dialogs on emergency services features with additional information 57Sunday, April 13, 14
  58. 58. Measure Success • Response Times • How good is current response time data? • How much data is enough to be valid? • Perception of users vs. hard data 58Sunday, April 13, 14
  59. 59. Data Integrity • Vandalism & Mistakes (OSM is a wiki project after all) • Monitor changes to map • Only extract new GPS maps after validating changes • Not a burden if you just stay on top of it 59Sunday, April 13, 14
  60. 60. Indemnification • OSM and its volunteers do not have resources to fight a lawsuit • How do we protect them in a modern, lawsuit prone environment? 60Sunday, April 13, 14
  61. 61. Contact Info • primary: rwelty@averillpark.net • secondary: nfgusedautoparts@gmail.com • OSM: nfgusedautoparts • Twitter: @nfgusedautopart 61Sunday, April 13, 14
  62. 62. Bonus Hydrant Image • Dry Barrel • Valve at water main • Safety Flange designed to fail • at grade level 62Sunday, April 13, 14
