What is Cadastral Surveying?

Cadastral surveying is the branch of land surveying that deals with determining and defining property boundaries. 

It involves measuring, mapping, and documenting land parcels to establish legal ownership and facilitate land registration.

The results of cadastral surveys are used for property deeds, taxation, and resolving boundary disputes.

In essence, cadastral surveying ensures that every piece of land has a clearly defined and legally recognized boundary.

Definition

Cadastral surveying is the measurement and mapping of land parcels to create or update cadastral records — official public documents that describe property boundaries, ownership, and value. 

 

Main Purposes

1. Define Legal Boundaries:

Establish the limits of land parcels for ownership and legal purposes.

2. Support Land Registration:

Provide accurate data for land title deeds, property transfers, and taxation.

3. Resolve Disputes:

Clarify or re-establish boundaries in cases of overlap or ownership conflicts.

4. Aid in Land Development and Planning:

Support urban planning, infrastructure development, and land management systems.

Key Activities

1. Field measurements of land boundaries using GPS, total stations, or drones.
2. Identifying and marking boundary corners with monuments or pegs.
3. Preparing cadastral maps and plans showing property boundaries.
4. Writing reports and legal descriptions for land title registration.
5. Working with land registries, legal authorities, and property owners.

Legal Importance

Cadastral surveys carry legal weight. They form the basis of:

• Land titles and deeds
• Boundary adjudications
• Property taxation
• Land ownership disputes

Example

If you buy a piece of land, a cadastral survey ensures:

• The plot size matches the deed.
• The boundary lines are correctly marked.
• Neighboring properties do not overlap.

Methods of Cadastral Surveying

Methods of Cadastral Surveying refer to the various techniques used to determine, mark, and record property boundaries accurately.

These methods depend on the purpose of the survey, terrain, and accuracy requirements, as well as the equipment available.

1. Chain Surveying (Traditional Method)

Description:

One of the oldest methods, using a chain or tape to measure distances directly on the ground.

Used for: Small, flat areas with simple boundaries.

Steps:

• Measure lines between boundary points.
• Take offsets to locate corners or features.
• Plot measurements on a plan.

Advantages: 

• Simple and inexpensive.

2. Compass Surveying

Description:

Uses a prismatic compass to measure bearings (angles) and a chain/tape to measure distances.

Used for:

Moderately sized areas where angular measurements are important.

Advantages: 

• Faster than chain surveying.

3. Plane Table Surveying

Description:

Fieldwork and plotting are done simultaneously using a plane table, alidade, and sighting device.

Used for:

Small-scale cadastral surveys, where direct plotting is convenient.

Advantages: 

• Quick, visual, and immediate plotting.

4. Theodolite Surveying

Description:

Uses a theodolite (or total station) to measure horizontal and vertical angles, along with chain/tape for distances.

Used for:

Accurate boundary determination in large or complex areas.

Advantages: 

• High precision; ideal for legal boundary surveys.

5. Total Station Surveying

Description:

A total station combines electronic distance measurement (EDM) and angle measurement, and records data digitally.

Used for:

Modern cadastral surveys requiring high accuracy and speed.

Advantages:

• High precision
• Data can be stored and processed digitally
• Faster and more reliable than traditional methods

6. GPS/GNSS Surveying

Description:

Uses satellite positioning systems (like GPS, GLONASS, or GNSS) to determine coordinates of boundary points.

Used for:

Large-scale cadastral projects, especially in rural or remote areas.

Advantages:

• High accuracy (with differential or RTK methods)
• Covers large areas quickly
• Coordinates directly tied to global reference systems

7. Photogrammetric & Drone Surveying (Modern Method)

Description:

Uses aerial photographs or drone imagery to map boundaries and land features.

Used for:

Updating cadastral maps, large land parcels, or inaccessible areas.

Advantages:

• Rapid data collection
• High-resolution mapping
• Useful for GIS integration

Choosing the Right Method

For condition recommended method are following:

• For Small, flat land Chain, Plane Table surveying
• For Hilly or large area, Theodolite or Total Station surveying
• For High accuracy required, Total Station / GPS surveying
• For Modern, large-scale mapping GPS Drone Surveying

Types of Cadastral Surveys

Cadastral surveying can be classified based on its purpose, area of coverage, or stage of land development.

Each type serves a specific legal or administrative function in defining and managing land ownership.

1. Original (New) Cadastral Survey

Purpose:

To establish property boundaries for the first time on previously unregistered or unsurveyed land.

Key Features:

• Conducted when land is first divided into plots or lots.
• Involves setting boundary monuments and creating cadastral maps.
• Forms the basis for issuing land titles or certificates.

Example:

• Surveying newly opened agricultural land or a new housing subdivision.

2. Re-Survey (Re-establishment or Re-determination Survey)

Purpose:

To reconfirm or re-establish existing boundaries that may have been lost, displaced, or disputed.

Key Features:

• Used when boundary marks are missing or unclear.
• Compares new measurements with original survey records.
• Often used for land dispute resolution.

Example:

• Re-measuring an old property to restore boundary stones or resolve overlaps.

3. Subdivision Survey

Purpose:

To divide a large parcel of land into smaller lots for sale, inheritance, or development.

Key Features:

• Establishes new internal boundaries.
• Each subdivided lot receives a separate title or parcel number.
• Common in real estate and urban development projects.

Example:

• A developer subdividing a 10-hectare tract into 100 residential lots.

4. Consolidation Survey (Amalgamation Survey)

Purpose:

To combine two or more adjoining parcels into a single property.

Key Features:

• Removes internal boundaries between adjoining lots.
• A new title is issued for the combined parcel.

Example:

• Merging several small farm lots into one large estate.

5. Boundary Survey (Verification or Demarcation Survey)

Purpose:

To locate, mark, and verify existing property boundaries on the ground.

Key Features:

• Confirms limits of ownership as per title deed or cadastral map.
• Used for fencing, construction, or legal verification.

Example:

• Before constructing a wall, an owner requests a boundary survey to avoid encroachment.

6. Topographical-Cadastral Survey

Purpose:

To combine ownership boundaries with physical features (like roads, rivers, and buildings).

Key Features:

• Produces maps that show both property limits and natural/man-made features.
• Useful for land-use planning and development.

Example:

• Mapping a village showing parcels, roads, and public infrastructure.

7. Urban and Rural Cadastral Survey

a. Urban Cadastral Survey

• Conducted in cities and towns.
• Requires high accuracy and dense mapping due to small, closely spaced parcels.

b. Rural Cadastral Survey

• Covers larger agricultural or forest lands.
• May focus on approximate boundaries with less density.

8. Administrative (Control) Cadastral Survey

Purpose:

To create a geodetic or coordinate framework for future cadastral work.

Key Features:

• Establishes control points across a region.
• Ensures consistency and accuracy of all cadastral maps.
