The visit
You start with a mission. The AI suggests a first scan. After that scan, the result is where to stand next, drawn on the view you already have, so the mission can be answered. On the administration building a mission might be the wall a new opening has to meet, the parapet a lift has to reach, the water on the walks, or one map for the crew.
One mission, as the person sees it
This is a replay. A crew set the administration building's 19 stations; the bridge planned its spots afterwards from each station's own points, and the agent's replies are scripted runs on the simulator.
The wall a new opening has to meet
Is the long facade plumb, within a quarter inch in ten feet?
The suggestion is a first scan with the wall in view. Station 3 is that scan. Drawn on it is where to stand next: on the road, about 40 m along the wall, past the shelter.
Where to stand
On the road, about 40 m along the wall, past the shelter.
From that spot
Nothing stands in front of the wall.
4.1 mm out of plumb (3/16 in) over 14.6 m. The top leans toward the side it was scanned from. The tolerance gives no allowance for 14.6 m of height. Flat to 7.6 mm RMS. Stations 3, 4, 5, and 6 saw it. The plane runs 44.4 m.
The parapet, and how high the lift goes
How tall is the wall, from the ground at its foot?
The suggestion is a first scan with the bays in view. Station 17 is that scan. The top is still ahead, and drawn on the picture is where to stand next: on the road, about 30 m past the rail.
Where to stand
On the road, about 30 m past the rail.
From that spot
The top of the wall is in view.
16.2 m, from the ground at its foot to the parapet the scan saw. Stations 15, 16, 17, and 18 saw it. The wall runs 15.4 m.
The walks, and the water already there
Where will water stand in this lot?
The mission is the water. The scans the other missions asked for already hold the ground. Crowns stand up. Gutters sit down. The road by station 4, the setup for the long wall, is one of the low places.
23 places of 0.5 m² or more, 10 mm or deeper. On the road by station 4, one of them holds 74 litres: 5.6 m², 28 mm deep. The deepest, 203 mm, is a planting bed in the courtyard. The ground falls about 3 m across the site.
One map for the crew
Give me the whole site in one map.
The mission is one map. Each mission placed a station. The mason, the windows, and the paving are looking at those stations in one frame.
The most any two overlapping stations disagree is 22 mm. The map is redrawn after every station.
