The Survey Map, officially called the Sketch Map here, shows verified plot boundaries for every survey number in Andaman and Nicobar Islands. Verify the map before purchase, not after. This guide covers how to view it online, get demarcation done, and what to do when boundaries on paper do not match the ground.

What is a Survey Map in Andaman and Nicobar Islands?

Definition

The Survey Map, locally called the Sketch Map, is the cadastral record showing plot boundaries, dimensions, and survey numbers for land parcels in Andaman and Nicobar Islands. It is maintained by the Revenue Department and integrated with the Dweep Bhoomi land records system.

The map does one job: it tells you where the plot ends and the neighbour's plot begins. Area on paper can be vastly different from what a seller shows on the ground. That gap between paper boundary and physical possession is where boundary disputes start, often years after the money changes hands. The Sketch Map, combined with a Tehsildar-ordered demarcation, closes that gap.

You can view the Sketch Map for free online. South Andaman district goes through http://db.and.nic.in:8080/bhunaksha. North and Middle Andaman and Nicobar go through http://as.and.nic.in/bhunaksha. Both portals integrate the Sketch Map with the textual Form-F record, so you see the plot shape alongside the ownership details. Useful for a quick check, but not the same as a certified on-ground demarcation. For any legal purpose: bank submission, boundary dispute, sale deed: you need the physical demarcation done by the Tehsildar.

State-specific note: Online Sketch Maps via Bhunaksha are for reference only. For a certified plot boundary record accepted by banks and courts, get physical demarcation done by the Tehsildar before buying.

How to Get a Survey Map in Andaman and Nicobar Islands: Step-by-Step

Viewing the plot map online is instant and free. Getting an official demarcation on the ground requires an application to the Tehsildar with a 75 paise court-fee stamp and a Form-F copy. Do both before committing to any purchase.

Online method (recommended)

Go to the Correct Bhunaksha Portal South Andaman: http://db

and.nic.in:8080/bhunaksha. North and Middle Andaman or Nicobar: http://as.and.nic.in/bhunaksha. The national portal at bhunaksha.nic.in also lists Andaman and Nicobar Islands.

Select District, Tehsil, and Village Work through the dropdown menus

The map loads for the village you select. All survey numbers in that village appear as coloured plots.

Click the Survey Number Click on the plot

The Sketch Map highlights the exact plot shape and pulls the linked Form-F data including the recorded owner name and area.

Cross-Reference with Form-F Compare what the map shows for boundaries with what the sale deed says

Note any discrepancy.

The Sketch Map shows boundaries as digitised from paper records. Old surveys may not reflect subdivisions that happened later. If the map looks out of date, apply for a physical demarcation.

Offline method (Sub-Registrar Office)

Write the Application Plain paper application to the concerned Tehsildar

Affix a 75 paise court-fee stamp. Mention owner details, survey number, village, and contact address including neighbouring plot contacts.

Attach Required Documents Submit a recent Form-F copy and the land map

These two documents are all that the official service requires.

Submit to the Right Office South Andaman: Port Blair, Ferrargunj, or Little Andaman

North and Middle Andaman: Mayabunder, Diglipur, or Rangat. Nicobar: Car Nicobar, Nancowry, or Great Nicobar.

Revenue Staff Visit and Mark Boundaries Revenue staff visit the site, physically mark the boundaries, and reconcile any difference between the Sketch Map and current possession

Bring the neighbouring plot owners along on the day of demarcation. Disputes resolved on the spot save a court visit later.

What Does the Survey Map Contain in Andaman and Nicobar Islands?

Five elements in the Sketch Map define what you actually own, not what the seller claims.

Field	Description	What to Verify
Survey Number	Unique identifier for the plot	Must match the Form-F entry and the sale deed
Plot Shape and Dimensions	Graphical boundary with measurements	Walk the plot; verify physical extent matches the map
Neighbouring Survey Numbers	Adjacent plots on all four sides	Cross-check with the deed's schedule of property for boundary descriptions
Village and Tehsil	Administrative location of the plot	Any mismatch here means you may be looking at the wrong plot
Date of Survey	When the map was last updated	Old survey dates mean boundaries may not reflect later subdivisions or encroachments

Good sign: Survey number matches Form-F, plot shape is clearly drawn with all four boundaries visible, neighbouring numbers are legible, and the demarcation date is recent.

Common Issues With the Survey Map in Andaman and Nicobar Islands

Four boundary problems dominate land purchases here; all are detectable before signing.

Physical Possession Exceeds Map Boundary The seller has fenced and is using more land than the Sketch Map shows

The extra area belongs to the neighbour or the government. A buyer inheriting this possession inherits the dispute.

Fix: Get demarcation done before purchasing. The Tehsildar staff mark the exact boundary; what falls outside is not yours to buy.

Outdated Sketch Map After Subdivision A plot was subdivided years ago

The online Sketch Map still shows the original survey number at full area. A buyer reading it assumes they are getting more than they are.

Fix: Pull the current Form-F and check the area. If the Form-F shows a subdivision but the map does not reflect it, ask the Tehsildar to update the map before proceeding.

Encroachment by Neighbour Not Visible Online The Bhunaksha map is a digitised record

Physical encroachments after the last survey do not appear. A neighbour may have built a wall two metres into your plot years ago.

Fix: Visit the plot and physically walk the perimeter against the Sketch Map before any agreement.

Wrong Survey Number Shown to Buyer Seller shows a Bhunaksha screenshot of a different, better-shaped plot with the same village

Numbers are easy to confuse in discussions.

Fix: Always pull the map yourself by entering the exact survey number from the Form-F. Do not use screenshots provided by the seller.

Demarcation Fee Not Paid Correctly Buyer or seller pays the wrong fee tier

Agricultural land above 2 hectares requires Rs. 50, not Rs. 25. An underpaid application is returned.

Fix: Confirm the exact land area from Form-F before calculating the fee. House site is Rs. 10, agricultural up to 2 hectares is Rs. 25, and between 2 and 4 hectares is Rs. 50.

Coastal or Forest Boundary Not Reflected in Map Plots near reserved forest or coastal zones may have additional restricted boundaries not shown in the cadastral Sketch Map

The map shows the survey boundary, not regulatory setbacks.

Fix: Cross-check the plot location on the State GIS portal at stategisportal.nic.in to see forest and coastal layers alongside the cadastral map.

Why the Survey Map Matters for Land Buyers in Andaman and Nicobar Islands

The Sketch Map is what turns a survey number on paper into physical ground.

📋

Boundaries Define What You Actually Own Area numbers in a sale deed are only as good as the demarcation behind them

The Survey Map is the only document that ties the number to a specific shape on the ground. Without it, what you own on paper may not match what you physically stand on.

⚠

Verify Before Purchase, Not After The WARNING here is direct: verify plot boundaries before committing

Disputes over where one plot ends and another begins are the single most common reason land deals in Andaman collapse post-purchase. A Tehsildar demarcation costs under Rs. 50. A boundary court case costs years.

🏦

Banks and Diversion Applications Need the Map Every major land process in Andaman, including Sale and Gift Permission, Diversion of Land, and any bank loan against the property, requires a recent Form-F copy and map

The map is not optional documentation. It is a mandatory attachment across multiple official processes.

🔍

Andaman and Nicobar-specific: Two Separate Bhunaksha Portals Unlike most Indian states with one Bhunaksha URL, Andaman uses two: South Andaman has its own portal at db

and.nic.in, while North and Middle Andaman and Nicobar use as.and.nic.in. Using the wrong portal returns no results, and buyers assume the plot has no digital map when it does.

Red flag: A seller who says a physical demarcation is unnecessary and points only to a Bhunaksha screenshot is handing you reference data, not legal verification. Get demarcation done before signing.

Frequently Asked Questions

What is the Survey Map or Sketch Map in Andaman Nicobar 2026?

The Sketch Map is the official cadastral record showing plot boundaries and survey numbers. Viewable free online via Bhunaksha but for a certified legal record, physical demarcation by the Tehsildar is required. Always do both before buying any land here.

How do I view plot boundaries online in Andaman and Nicobar?

South Andaman plots go through db.and.nic.in:8080/bhunaksha. North and Middle Andaman and Nicobar plots go through as.and.nic.in/bhunaksha. Select district, tehsil, village, and click the survey number. The Sketch Map and Form-F data appear together.

How do I apply for land demarcation in Andaman Nicobar?

Write a plain paper application to the concerned Tehsildar. Affix a 75 paise court-fee stamp. Attach a recent Form-F copy and the land map. Submit at the Tehsildar office covering your district. Revenue staff will then physically mark boundaries on the ground.

How much does demarcation cost in Andaman and Nicobar?

House site: Rs. 10. Agricultural land up to 2 hectares: Rs. 25. Agricultural land between 2 and 4 hectares: Rs. 50. Confirm the land area in Form-F before paying. Underpaid applications are returned and cause delays.

What documents are needed for demarcation in Andaman?

A recent copy of Form-F and the land map. These are the two mandatory attachments. Submit them with a plain paper application and 75 paise court-fee stamp addressed to the concerned Tehsildar in your district.

Is the Bhunaksha Sketch Map legally valid in Andaman and Nicobar?

No. The online Sketch Map at the Bhunaksha portals is a reference tool maintained by the Revenue Department. For bank submissions, boundary dispute resolution, or court proceedings, you need a physically certified demarcation order from the Tehsildar.

What is the difference between the Sketch Map and demarcation in Andaman?

The Sketch Map is the digitised boundary record viewable online. Demarcation is the physical process where Tehsildar staff visit the plot and mark the actual ground boundaries. The map shows what records say; demarcation confirms what the ground says.

Why are there two Bhunaksha portals for Andaman and Nicobar Islands?

South Andaman uses db.and.nic.in:8080/bhunaksha and North and Middle Andaman plus Nicobar use as.and.nic.in/bhunaksha. They are district-level systems, not a single UT portal. Using the wrong one returns no results for the plot you are searching.
