How To Map Your Farm

Introduction

A farm is a set of boundaries before it is anything else. Every hour you pay for happens inside one of them.

You do not need a drone, a surveyor or a GIS course. You need your lot and plan numbers, an hour at the kitchen table, and a decision to call each piece of ground by one name and keep to it.

This chapter is about turning ground into a record.

There is already a map. It lives in the manager’s head, and it works — until the day somebody else has to use it. A new supervisor is told to “take the crew to the back of Number Three”, and Number Three turns out to mean two different paddocks depending on who you ask. A contractor invoices for 14 hectares you believe is 11. A worker’s day is recorded against a block that was pushed out two winters ago.

It is tempting to call that a mapping problem and buy software for it. It is not. It is three problems at once — a naming problem, an area problem and a memory problem — and all three go quiet the moment the farm has a single written record that everybody reads from.

The record does not have to be elaborate. It has to be shared, and it has to be the only one. A farm with two maps has no map — it has an argument that has not started yet.

Three things break when the map lives in one head:

• Rosters. A shift is sent to a block, not to a paddock somebody will point at in the morning.
• Rates. A piece rate that changes between an old orchard and a young one needs the two to be separate things on paper before it can change between them.
• Records. When somebody asks where a worker was on the 14th, the answer is a block with an area and a crop, not a guess.

None of this is work you do twice. The property record you build in an afternoon this week is the one your rosters, your spray records and your piece rates hang off for as long as you farm the place.

Should You Map It All?

The ground worth mapping first is the ground you will pay somebody to work this season.

The instinct is to draw the whole property — every gully, every dam, the scrub at the back, the house block. It feels thorough and it takes a week. Then nothing hangs off most of it, because nobody will ever roster a crew into scrub, and the parts that do matter are buried in the parts that do not.

There is a second cost, and it is the one that bites later. A record with sixty objects in it needs somebody to maintain sixty objects. The fallow corner gets planted, the dam silts up, the scrub is cleared, and none of it is updated — so a third of the map is quietly wrong, and now nobody trusts the two thirds that are not.

A good first pass covers:

• Every block that will be picked, pruned, sprayed or cut this season.
• The sheds, the packing area and anywhere a crew starts or finishes a day.
• Ground that is leased in or out, because the boundary matters more there than anywhere else.

It can wait on:

• Fallow ground with no plan for it this year.
• Remnant vegetation, unless it constrains spraying.
• Every individual tree. Rows are enough to start; trees come later, if ever.

You can add the rest whenever you like. A property record is not a survey you commission once — it is a working document, and the version that exists on Monday is worth more than the perfect one that arrives after the pick.

Where to spend the afternoon, in order:

Find Your Real Boundaries

Your legal boundary already exists, drawn to survey accuracy, and it is public. In Queensland it lives in the Digital Cadastral Database — the same parcel data the council, the valuer and the surveyor work from.

The alternative is tracing a line over a satellite photo, and a traced line is wrong in a specific and expensive way: it follows the fence. Fences move. Fences get built inside the boundary to dodge a wet corner, or ten metres out because that is where the old one stood. A fence line traced as a boundary can be out by several hectares on a long block, and every area calculation after it inherits the error.

The error then compounds quietly. A block recorded 12% larger than it is makes every yield-per-hectare figure nearly 11% low, makes the spray rate wrong, and makes a contractor’s invoice look reasonable when it is not. Nobody notices, because there is nothing to notice it against.

To find the parcels that make up your farm you need one of:

• Lot and plan. Written as Lot 4 on RP712345 or 4RP712345. It is on your rates notice, your title search and your contract of sale.
• The title reference. A number like 50123456, on the same documents.
• The address. Rough, but enough to find the parcel and confirm it by eye.

Most farms are not one parcel. A working property of any age is usually four to twenty lots accumulated over decades, some of them slivers left by a road realignment nobody remembers. That is normal. Pull them all in and let the record hold them together; you do not need to consolidate titles to run a farm on one map.

Leased ground goes in at the same time. It is the piece most often left out and the piece where the boundary matters most, because you are paying for a stated area and working to a fence that may not agree with it.

What that looks like when the parcel data is already there:

Parcel data is Queensland-only today, drawn from QSpatial DCDB records under CC BY 4.0. Outside Queensland the same structure works — you supply the boundary and the blocks hang off it exactly the same way.

Lots, Plans and What They Mean

Four words do most of the work in Australian land records. Learn them and a rates notice stops being a bill and starts being a map key.

Lot

One parcel of land. The smallest unit that can be sold, mortgaged or leased on its own. Your farm is made of lots the way a wall is made of bricks, and like bricks they are rarely the shape you would have chosen.

Plan

The survey drawing the lot was created on, identified by a prefix and a number — RP, SP, CP and others. Two lots on the same plan were usually created in the same subdivision, which is why neighbouring parcels so often share one.

Title

The ownership record over one or more lots. A title can cover several lots, so “one title” does not mean “one paddock”, and a farm on a single title can still be nine separate parcels on the ground.

Tenure

How the land is held — freehold, leasehold, or one of the state land categories. It rarely changes how you roster a crew, but it changes what you may do to the ground, so it belongs in the record rather than in somebody’s memory.

Keep the lot and plan attached to each parcel. It is the number every outside party — surveyor, agronomist, insurer, valuer, buyer — asks for first, and looking it up once beats looking it up every time.

What these four words do not tell you is what is planted. Titles and plans describe ownership, not farming, and they change hands rather than change crops. A block is what closes that gap between the legal picture and the working one.

Split It Into Working Blocks

A lot is a legal object. A block is a working one. The two almost never line up, and the map only becomes useful when you stop pretending they do.

A block is the smallest piece of ground you would ever send a crew to on its own. That is the whole definition, and it beats acreage or crop type as a test, because it is the question you are actually answering when you build a roster.

Split a lot into separate blocks when any of these is true:

• Different crop. Mangoes and bananas are never one block, even inside one fence.
• Different age. A four-year-old planting and a fifteen-year-old one pick at different rates and need different piece rates.
• Different variety. If they are picked in different weeks, they are different blocks.
• Different irrigation. One valve, one block, is a rule that pays for itself the first time you shut something off.
• A physical divide. A road, a creek or a headland the crew has to walk around.

Do not split for the sake of precision. Twelve blocks a manager can hold in their head beat sixty that need a lookup, and a block you never roster separately is a block you should merge back. If two pieces of ground are always worked together, they are one block with a fence through it.

The split that costs the most is the one drawn on soil type, or on some agronomic line that never becomes an instruction. It reads well on a map and it means nothing at half past five in the morning, because you cannot send eight people to a soil type.

The same twelve hectares, three ways:

Blocks change. A planting is pushed out, a lease ends, two small blocks become one after a replant. When that happens, close the old block rather than editing it into the new one — the seasons it worked under its old shape still have hours and piece counts attached to them, and rewriting the block rewrites their history with it.

Name and Number Your Blocks

A supervisor reading a roster at half past five in the morning does not open a map. They read a name and drive.

Names do more work than boundaries do. If the name is ambiguous the crew is in the wrong place for an hour, and no amount of surveyed accuracy behind it buys that hour back. Names are the interface; the rest of the record is plumbing.

Four rules make a name work:

1. 1It is what people already say. If the crew calls it the Airstrip Block, the map calls it the Airstrip Block. A record that renames the farm loses to the farm every time.
2. 2It is unique out loud. “Three” and “Tree” over a two-way radio is a real morning lost. So is Block 3 on two different properties in the same organisation.
3. 3It does not encode a fact that will change. “Mango 4” becomes a lie the year the block is pushed out and replanted to avocados. Name the place, not the planting.
4. 4It sorts the way you drive. Numbering blocks in the order you reach them turns any list into a route, and turns a new employee into somebody who can follow it.

Write the names down once, tell the supervisors, and put them on the gate. The gate sign is not a nice touch — it is the point at which the record and the ground agree, and it is what lets somebody on their second day find a block without phoning anyone.

Then stop renaming. A block that changes name mid-season splits its own history in two: half the season under one name, half under another, and no way afterwards to add them up.

If a name genuinely has to change, change it once, at the end of a season, and keep the old one written beside it for a year. The people who used the old name for six years will use it for one more, and the map should be able to hear them.

Check It Against the Ground

A map is a claim about the world. Before you roster anyone against it, go and check the claim.

The drive takes an afternoon and answers four questions:

• Does the boundary match the fence? Where it does not, the record is usually right and the fence is in the wrong place — but you want to know which, and you want to know before a neighbour tells you.
• Do the areas look right? If a block you have always called twenty acres comes back as 6.4 hectares, one of those numbers has been wrong for years. A hectare is 2.47 acres, and that conversion is where most of these arguments end.
• Is anything missing? Leased ground is the usual gap, followed by the small parcel bought from a neighbour in 2014.
• Does the name on the gate match the name in the record? Fix whichever is easier to change.

Expect the two areas to differ, and record both. Surveyed area is the ground inside the legal boundary, and it does not care that four metres of one end is headland you can neither plant nor pick. The legal area is what rates, leases and contracts run on; the workable area is what you plan a pick against. Keep only one and you will be converting between them in your head forever.

Take somebody who has worked the place a long time. A boundary argument is usually settled in thirty seconds by a person who remembers when the fence was moved, and never settled at all by two people reading a plan.

What the finished record gives you:

What comes next:

The property is now a record instead of a memory, and every block has a name a stranger can find. The next thing that ground needs is people — hired, checked and signed up before the first shift, which is what Chapter II covers.
