Relevant Typesof 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
Alternatives
• “Data Terminals”• Princeton Project• Active911.com• CAMEOfm• Others
3Sunday, April 13, 14
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

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
7Sunday, April 13, 14
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
8Sunday, April 13, 14
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
9Sunday, April 13, 14
addressing in large apartment complexeslack of knowledge about neighborhoodswater system issues - private hydrants, no way to determine capacity of hydrants
Extreme Mutual Aid
• 9/11• Hurricane Sandy

dry barrel - discuss featuresSteamer vs hose connectionscolor schemes contain no real information
Hydrant Gallery
• Wet Barrel• West coast• UCLA colors

Hydrant Gallery
• Wynantskill, NY
• AWWA color scheme
• Blue Caps & Bonnet
• Class AA Hydrant
• > 1500 GPM
13Sunday, April 13, 14
capacity helpful, but you don’t know the capacity until you see the hydrant
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
14Sunday, April 13, 14
distinguish between static (head) pressure and pressure while operating hydrant
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
15Sunday, April 13, 14
Hydrant Gallery
• Bethlehem, NY• Green = large main• Orange = medium
main• Red = small main

Hydrant Gallery
• Tag on Steamer connection instead of paint for flow capacity
17Sunday, April 13, 14
problem with painters
Hydrant Gallery
18Sunday, April 13, 14
no Steamer connection on left, only steamer connection on right
Snow
• “If I have to dig one out of the snow it better be a good one”
19Sunday, April 13, 14
Out of Service
• Not all Hydrants are operational
20Sunday, April 13, 14
Out of Service
21Sunday, April 13, 14
can’t see out of service condition until you see the hydrant
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
22Sunday, April 13, 14
reference extreme mutual aid
Is this a hydrant?
• Rural VFD, no pressurized water system
• Lawn Ornament

Dry Hydrant, but...
25Sunday, April 13, 14
water source is higher than hydrant
Wrench Types
26Sunday, April 13, 14
also apparently triangular and conventional hex heads

Color Code extension
29Sunday, April 13, 14
color code for capacityUse case: observing hydrant capacity while riding in to the scene, stopping tostart laying hose on the way in
OSM Tagging
• Some current tags• emergency=fire_hydrant
• fire_hydrant:type={pillar,pond,underground}
• colour={red,yellow,green,blue,...}
• diameter=12 inches
30Sunday, April 13, 14
pillar - used in Germany, correct in US usage but not common. not used in UK.diameter - main diameterpressure - in bar (head pressure?), not relevant to US operating practicepond - inappropriate conflation
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?
31Sunday, April 13, 14
LPM for non-US jurisdictions
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}
32Sunday, April 13, 14
Other Properties
• Outlet sizes, threads• Wrench type and size
• triangular, square, pentagonal, hexagonal
33Sunday, April 13, 14
• Orientation
• Steamer valve perpendicular to curb vs 45 degree angle
Orientation probably not that important
Dry Hydrant Tags
• Dry hydrant conditions• weeds• low water levels (winter)• lift
34Sunday, April 13, 14
Landing Zones
• Landing Zones (Med Evac)• current tags that are relevant
• name• operator
• need to characterize additional information
35Sunday, April 13, 14
don’t want to use the existing aviation tagging, as that is for general purpose landing facilities, not for emergency LZs
Hazmat Data
• In the US, this actually information of public record
• Probably not be appropriate in OSM• Candidate for private data store
36Sunday, April 13, 14
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
37Sunday, April 13, 14
Other Considerations
• Policy on overriding One Way, Turn Restrictions
• Do we need different maps for different classes of emergency vehicles?
