# Leaflet maps

Plan a letterbox drop — draw a delivery area, let Prenso order every address into a walkable route, adjust it by hand, and print a sheet for your team.

A map is a delivery area, the addresses inside it, and the order you walk them.
It is the unit you assign to a person, so a good map is one someone can finish
in a single outing.

If you have run a letterbox drop off a printed street map before, this is the
step that replaces it — with the difference that Prenso knows how many addresses
are in the area before anyone sets off.

## Creating a map

Open **Maps → Explore**. You get the full country with your workspace's address
data behind it and your existing maps drawn on top, so you can see what is
already covered before adding to it.

### Draw an area

Use the draw tool to trace a polygon around the streets you want. Click to place
each corner and close the shape to finish. As soon as an area exists, Prenso
counts the addresses inside it and shows the total, so you can adjust before
committing.

Drawing is the right choice when the boundary is something physical: a river, a
railway line, a main road nobody wants to cross with a bag of leaflets, or
simply how far someone can walk in an hour.

### Select boundaries

Turn on a boundary layer and click the areas you want instead. Prenso merges
your selection into a single map and names it after the areas you picked.

Selecting is the right choice when you want consistent, repeatable patches.
Statistical Area 1 units are small enough to be walkable and are published
nationally, so a map built from them lines up with census data and looks the
same every time you rebuild it.

You can combine up to 20 areas into one map. If you're reaching that, the map is
almost certainly too big to walk in one go — split it.

> Not every boundary layer can be used to create maps. Electorate boundaries, for

See [Map data](/docs/workspaces/map-data) for what each layer contains.

## Sizing an area

The address count is the number that matters, and Prenso shows it before you
create anything. A rough guide for planning on foot:

| Addresses | Roughly                                |
| --------- | -------------------------------------- |
| 100–150   | An hour, comfortable for a first-timer |
| 200–300   | A solid afternoon                      |
| 400+      | Usually worth splitting in two         |

Suburban streets with long driveways take much longer per address than a row of
townhouses, so treat these as a starting point and adjust to your own patch.

## Generating a route

A new map has addresses but no order. Select **Auto-generate** and Prenso builds
a walking route.

It works the way an experienced deliverer does. Addresses are grouped by street
**and by side of the street**, so odd and even numbers are separate runs — you
walk up one side and back down the other instead of crossing the road at every
house. Each run is kept intact and in house-number order, and Prenso then
searches for the order and direction of runs that keeps the total walking
distance down.

The result appears in the **Route** panel beside the map, as numbered
segments you can expand.

> Very large areas can't be auto-routed — beyond about a thousand street-side
> segments, Prenso asks you to shrink the boundary instead. That is well past
> the size anyone can deliver in one go, so hitting it is a sign the map wants
> splitting.

## Editing a route

Auto-generate gets the geometry right. It doesn't know your patch. In the
Route panel you can:

* **Reorder segments.** Drag a segment to move it. Use this for a shortcut
  through a reserve, or to finish nearest to where the car is parked.
* **Reorder addresses within a segment.** Drag individual addresses when the
  numbering doesn't match the walk.
* **Remove an address.** Drop a property that has a no-junk sticker, a locked
  gate, or a dog.
* **Delete a segment.** Drop a whole street someone else is covering.

Select **Save** to keep your changes. The address count and route length update
as you edit, so you always know what you are asking someone to walk.

## Printing

Select **Print** and choose a layout:

* **Route sheet** — the map, a tick-off list of streets, and a sign-off block.
  This is the one to hand to a volunteer: they can mark off streets as they go
  and sign the sheet when they finish.
* **Street list** — the map and a plain list of streets, with no checklist. Use
  it as a reference for someone who already knows the area.

Both generate a PDF you can print or email. The sheet includes the address
count and total distance, so whoever picks it up knows what they've taken on.

An area that runs north–south is printed on its side, so it fills the page
instead of sitting in a thin ribbon down the middle. North is therefore not
always up on the sheet, which is why every printout carries a north arrow. The
compass at the bottom right of the map on screen answers the same question for
the map you are working on — and selecting it squares the map back up if you
have rotated or tilted it. What is up on screen has no effect on the printout.

## Managing maps

**Maps → List** shows every map in the workspace with its address count and
route distance — your inventory of areas, and how much walking each represents.

For coverage — which areas have been done and which are still out — use a
campaign's **Map** tab instead. Maps are permanent; coverage belongs to a
particular distribution. See [Campaigns](/docs/workspaces/campaigns).

Maps count against your plan's per-workspace limit. Deleting one frees the slot
straight away, but also removes it from any campaign it was assigned to, so
archive-by-deletion is not a good habit mid-campaign.
