Land Demarcation and Boundary Survey with DGPS

What is land demarcation?

Land demarcation means finding and marking the true boundary of a plot from its legal description: sale deed, allotment letter, sanctioned layout or revenue map. A demarcation survey measures the site, computes where the corners should be and marks them with pillars or pegs.

Two other phrases name the same work. A boundary survey means the measuring and drawing part, and plot measurement is how most owners describe it on the phone. All three ask whether what is built matches the papers.

Private boundary survey or official demarcation?

They differ, and you may need one, the other or both. Official demarcation of farm and village land is done by the state's revenue staff after an application at the local revenue office. In Haryana and Punjab, field revenue staff work from the village map and killa layout; in Uttar Pradesh the lekhpal makes the measurement. Their report is the official record.

A private survey is faster and more detailed, with exact coordinates, a CAD drawing and an area statement. It does not override the land records, and every drawing says so. Owners use it to check a plot before buying, settle facts with a neighbour, brief a lawyer or prepare for the official visit. In colonies, sectors and estates with an approved layout, the layout plan's dimensions are the reference.

Before relying on a wall or fence, see how far it sits from the computed line, as in the drawing below.

How do we measure and mark a plot?

In six steps; most single plots finish in one field day.

1. Papers first: you share the deed, layout or revenue map and any earlier survey, and we note dimensions, reference marks and key corners.
2. Control: a DGPS base station fixes points in the open so every measurement sits on one grid; see how long a DGPS survey takes on a typical plot.
3. Existing evidence: old pillars, corner stones, walls, road edges and neighbours' boundaries are picked exactly as found.
4. Computation: record dimensions are fitted to the reference marks to calculate the corners.
5. Marking: pillars or pegs go on the computed corners with the owner or a representative present.
6. Drawing: the record line, ground features, any difference and the area are drawn and issued.

Where revenue records are the reference, work starts from known stones or killa corners, and tracing them sets the effort, so such jobs are priced after we see the papers.

Why do walls and papers stop matching?

Mostly through small, honest errors that add up over the years, not deliberate grabbing. Knowing the causes helps owners discuss a difference calmly.

• Built by eye: a mason sets out a wall from a neighbour's wall, not the corner pillars, and later plots inherit the shift.
• Lost pillars: corner stones vanish during levelling, road widening or farming, and new ones go roughly where people remember.
• Tape and chain measurement: older surveys measured along the ground, sag and slope included, so long frontages drift by a fraction of a metre.
• Unit mix-ups: square yards in a deed, square metres in a layout and kanal-marla in the revenue entry disagree through rounding.
• Road and drain changes: a widened road or new drain moves the edge people treat as the front line.

Our drawing shows the size and place of any difference, often the first fact both sides agree on.

What should you bring for agricultural land?

The khasra or killa numbers, any copy of the revenue map, and the names of neighbouring owners. Recent revenue extracts confirm the plot numbers before the visit. A villager who knows where the old stones stood can save hours, so bring one along.

What units will the plot measurement use?

Square metres and square feet always, plus the local unit you name. Local units differ by state, which is a common source of confusion between buyers and sellers.

• Haryana and Punjab: 1 acre = 8 kanal; 1 kanal = 20 marla; 1 marla = 272.25 sq ft. In consolidated villages a killa is about one acre.
• Urban plots across NCR: square yards (gaj) are common in sale documents; 1 sq yd = 9 sq ft.
• Bigha and biswa: the size of a bigha changes from state to state, so we state which basis we used on the drawing.

What you receive

A demarcation drawing, a coordinate list and an area statement, normally within 3 working days of the field visit.

Table note: once a new wall is up on the marked line, booking an as built survey records where it stands, which is useful for sale or loan files later.

Planning to build after the boundary is fixed?

Then add levels and services to the same visit instead of calling a crew back. A topographic survey gives the architect a site plan with spot levels, contour lines, trees and drains; see topographic survey: scope, time and cost. Cables or pipes may lie under a road-frontage wall line, so our GPR team scans that strip; read GPR survey deliverables to see what the scan returns.

Land demarcation rates – November 2026

From ₹8,000 per plot up to one acre, plus ₹2,000 for each extra acre. A 2.5-acre plot comes to ₹11,000, and a 500 sq yd house plot falls within the ₹8,000 base. Demarcation that depends on khasra or killa records is priced after we have seen the papers. GST is extra.

In Delhi NCR the surveyor reaches site the same day or within 1 working day. Elsewhere in India, a team member based in the district starts immediately or within 1 working day, with any travel cost shown in the written quote. Every job uses company-owned equipment, including 4 DGPS base + rover sets and 6 total stations, at 1–2 cm horizontal by DGPS and 5 mm + 3 ppm by total station. To fix a date, share your project details with the papers you hold.

Frequently asked questions

Will your demarcation be accepted in court?

Our drawing is a professional measurement of the property boundaries and can be produced as evidence, but it is not official revenue demarcation. Your lawyer can advise how to use it in your case.

Should the neighbours be present?

It helps. Pillars set with both sides watching are far less likely to be disputed later, and we photograph who was present.

What if my papers and the wall do not match?

We draw both and measure the difference. Deciding which is right is for the owners, or for the revenue office or court if it comes to that.

Can you demarcate land with only a khasra number?

In most cases, if the revenue map can be obtained and reference stones survive nearby. Such jobs are priced after we see the papers.

How do I apply for official demarcation in Delhi NCR?

The application goes to the revenue office for the area. For the steps, read more on demarcation survey Delhi.

Do you set permanent pillars?

Yes, we can set concrete pillars or mark existing ones; the type is agreed in the quote.
