Start anywhere in Anytown.
A street fits its nearest block. An address selects its building.
FIRE BUILDING
Tap the scene at street level to position this company.

TARGETS
LINES
Tap a bed, then tap the entry: a building wall or the ground. Loads come from the Fleet tab.
RESERVED AREASPick an area, then tap the scene. Sizes are illustrative. Truck setup and ladder-removal space are checked against them.
ONE-WAY STREETSArrows mark every street with a recorded direction: solid = confirmed by the department, open = a public map (OpenStreetMap, matched to the city centerlines). No arrow = no recorded direction; the arrival routes it as two-way and says so. Your word beats the map.
WHAT THIS WAY IS
Apparatus drive it
A line goes through it
A rig at its mouth blocks a line
Read-only on a phone. Set a direction, or what a way is, in the Workshop on a desktop.
OBSTRUCTIONSTrees come from the city: the tree inventory (height and drip radius as surveyed) and the base map's street trees. Tap one to hide or edit it for this exercise. OpenStreetMap maps a few wires and poles here, with no clearance; a street with none is unknown, not clear: Wire the block puts poles along a curb line in one tap. Everything here blocks the aerial and cuts its scrub; numbers left at a default are assumptions.
Parked carsThe exercise's condition, not map data: per block, both sides, one side or none. Illustrative cars at 6.5 m centres, with gaps at corners, driveways and hydrants. A rig cannot stand on one; a line across one is a finding. Off unless you park a block.
PLACEMENT FEEDBACKGeometry only: footprints, working space, mapped pavement and buildings. A clear result is not a correct-position grade.
OVERHEADWhere this scene's wires come from. The lidar wire class is not loaded; OpenStreetMap maps few lines here and no clearances. A street with none mapped is unknown, not clear.
COMMAND BOARDWhat the ground shows against each company's job on the board: a water supply company with no line to a plug, an attack company whose line does not reach, a roof company whose aerial is bedded or reaches no roof edge, a staged company sitting in the scene. Facts, not a grade; nothing here says which assignment is right.
ACCESSWhat the lines on the ground do to the next company in: the streets they cross, the working spaces and reserved areas they run through, and the street each rig sits on.
HOSE LINESStretch a line from an engine (Position tab) or lay supply (Water tab).
Length on the ground against the bed's load. No friction loss, pressure or flow is modeled.
ARRIVALEach company comes in by the approach set in the exercise, or from its house: the route over the mapped street centerlines, obeying one-way streets, with what is on the ground before it. A laid line closes a street where it crosses it. Distance only: no drive times, driving simulation, lane widths or turning.
STREETSEvery one-way street in view, its direction in words and where that comes from. Confirmed is the department's word; public map is OpenStreetMap or the city GIS. A street with no recorded direction is not listed and is routed as two-way.
SCRUBScrub is the stretch of each face the tip can sweep: within reach, with nothing between the turntable and the wall — the truck's own cabs, other rigs, authored wires and trees, other buildings. Sector geometry only; no stream reach.
AERIAL REACHSet up a truck near the fire building to see what the position lets the aerial touch.
From the reach table where it publishes a point; between points an assumption, marked so. Obstruction is other buildings and the wires and trees authored for this exercise; no dataset carries them.
HYDRANTSThe city's hydrants and mains.
The city’s GIS water layers (utility field data, 2017): each hydrant where the city recorded it, the main size on its record, and the bonnet colour the city recorded where it recorded one. The colour is the city's NFPA 291 class, not a flow test run in this app. No flow, pressure or capacity is modeled. Tap a hydrant for its record, its nearest mapped main and its distance along the streets to the selected apparatus.
Bonnet, as the city recorded it (NFPA 291, rated at 20 psi residual): Red · Class C, under 500 gpm Orange · B, 500–999 Green · A, 1,000–1,499 Light blue · AA, 1,500+ Not recorded
Map camera: mains under the streets, drawn by diameter and labelled “6 IN” like the tablet. Zoomed out, plugs thin and only the big mains are labelled.
SUPPLY LINESLay from the plug.
Forward lay: tap the plug, tap bends along the approach, then tap where the engine stops. Reverse lay: the engine stays where it is; tap the plug and the line runs from its rear supply bed to it.
Select a fire building to list the hydrants around it.
