A caller reports they are at a location described as '2 miles east of the water tower on County Road 18.' What type of landmark is a water tower for dispatch purposes?
Answer: A fixed, visible reference point useful for rural location estimation
Water towers are permanently fixed, often visible from a distance, and commonly used as reference landmarks in rural and suburban areas.
A mutual aid request sends your unit into an unfamiliar neighboring jurisdiction. Which action should you take first before entering that area?
Answer: Obtain a map or GPS coverage of the neighboring jurisdiction's street layout
Having a map or GPS data for the unfamiliar area prevents navigation errors and delayed response in mutual aid situations.
A caller reports a structure fire and says the building's address faces north, but they are calling from the rear (south side) of the building. Responding units should be told to access via:
Answer: The alley or rear road on the south side of the building
Directing units to the rear of the building helps them position correctly when the caller is reporting from the south side where the fire may be most visible.
On a dispatch map, what does a 'dead end' or 'cul-de-sac' notation mean for responding units?
Answer: There is only one way in and out, requiring careful positioning of units to avoid blocking egress
Dead ends and cul-de-sacs have only one entry/exit point, so units must position themselves to avoid blocking the only escape or additional response route.
A caller says they are at 'the old mill building on River Road.' The CAD system shows no address match for this description. What is the dispatcher's best next step?
Answer: Ask the caller for the nearest cross-street or any visible street address on surrounding buildings
When a landmark description doesn't match the address database, the fastest solution is to get a verifiable nearby intersection or visible address from the caller.
Which map reading skill is most critical when dispatching to a large campus (hospital, university, or industrial complex) with multiple numbered buildings?
Answer: Identifying the correct building number and the nearest accessible gate or entrance
Large campuses have multiple structures, and directing units to the specific building number and accessible entry point prevents critical delays.
A caller says their GPS is telling them they are at coordinates 'north 41 degrees, west 87 degrees' (approximate Chicago-area coordinates). A 911 dispatcher who understands geographic coordinates can use this to:
Answer: Plot the caller's position directly on a GIS-enabled dispatch map
Latitude and longitude coordinates can be entered directly into GIS-enabled CAD systems to pinpoint a caller's exact location on a map.
