# Floor plans

> Marking up a drawing of a site, and colouring it by what needs attention.

The register knows where every asset is and can't show you. A floor plan answers *which of these is
the one with the problem* in one look.

## Uploading a drawing

On the **Floor plans** tab of [a site](/sites/detail): **Upload a drawing**, as a PNG, JPEG or WEBP
image. Say whether it's of the whole site or of one location — a plan of the whole site marks its
locations and anything standing on them; a plan of one building or floor marks the places inside it
and the assets in them.

A site can hold several plans — a ground floor, a first floor, a yard — shown as a row of chips you
can drag into the order you want.

## Marking areas

With a plan open, draw a rectangle or a polygon over an area and link it to a location or an asset.
Drawing and reading are different modes, so opening a plan never risks moving a region by accident —
switch into drawing mode deliberately.

## What the colours mean

Each area is coloured by the worst thing currently true of what's linked to it:

| Colour | Means |
| - | - |
| **Needs attention** | An asset here is down, or a service level is breached |
| **Worth watching** | Work here is open or overdue, or maintenance is due |
| **Nothing open** | Nothing currently needs attention |
| **Nothing here** | The area holds nothing — deliberately not shown as healthy |

Which signals count as "needs attention" versus "worth watching", and the health-score thresholds
that go with them, are a configurable rule — **What the colours mean** on the tab shows and edits it.
Colours refresh on their own roughly once a minute, because they describe a live condition rather
than a property of the drawing.
