Land Survey & Drone Mapping in Bangladesh
A survey measures land and structures so designs, boundaries and quantities rest on real coordinates instead of guesses. RTK GNSS is fast in open ground, total stations handle detail and setting out, mouza surveys match a plot to government maps, and drones map large areas quickly. Many projects combine two or more of these methods.
We survey for real-estate developers, land buyers, factory expansion projects, utilities and design consultants across Chattogram, Dhaka, Gazipur and Narayanganj. Every job starts with what the result is for: a boundary check, a topographic base for design, setting out piles or a volume count. We then choose the instruments, tie the work to control points, process and check the data, and deliver drawings in the coordinate system and file formats your engineers or architects already use.

Survey & Drone
RTK GNSS survey
An RTK GNSS survey uses satellite receivers with real-time corrections from a base station or network to fix positions to centimeter-level accuracy under open sky. It is often the fastest way to set control points, map boundaries and survey large open sites. Accuracy falls near tall buildings and under dense trees, where a total station takes over.

Total station survey
A total station is an electronic instrument that measures horizontal angles, vertical angles and distances to fix points from known positions. It is the standard tool for setting out piles, columns and gridlines, checking as-built work and surveying built-up or wooded areas where satellite positioning struggles. Accuracy depends on the instrument, setup and survey procedure.

Mouza & land survey
A mouza survey finds your plot on the government mouza map and marks it on the ground. The surveyor locates the dag on the map, measures the actual boundaries and area, and shows where possession matches or differs from the record. Buyers and developers use it before purchase, design or building a boundary wall.

Drone mapping & GIS
Drone mapping flies a camera drone over a site in a planned grid, then processes hundreds of overlapping photos into a measurable map, elevation model and 3D surface. With ground control points measured by RTK, it gives reliable mapping accuracy over large areas in far less field time than walking the site. Flights in Bangladesh need CAAB permission.

Which survey method fits your project?
The method follows the question you need answered, and many jobs combine two.
| Service | Best for | How it works |
|---|---|---|
| RTK GNSS survey | Best for: Open sites, control points, boundaries and large topographic surveys | How: Satellite positioning corrected in real time by a base station or network |
| Total station survey | Best for: Setting out piles and columns, building detail and areas under trees | How: Measures angles and distances from known points to precise targets |
| Mouza & land survey | Best for: Land purchase, boundary checks and plot identification against government maps | How: Locates dag plots from mouza sheets and compares them with possession on the ground |
| Drone mapping & GIS | Best for: Large sites, stockpile volumes, progress records and GIS base maps | How: Overlapping aerial photos processed into orthomosaics, elevation models and contours |

Survey & Drone: questions buyers ask
Start with a mouza and land survey. It locates the dag on the mouza map, measures what is on the ground and shows any mismatch with neighbors, roads or water bodies. Pair it with a legal check of the khatian, deeds and mutation by a lawyer, because a survey shows position and area, not ownership.
We observe in WGS84 and deliver in UTM or the Bangladesh Transverse Mercator (BTM) grid, whichever your consultant or authority uses. Heights can be tied to a local benchmark or the datum your designer specifies. Agreeing this at the start avoids drawings that do not line up later.
Cost depends on the site area, terrain and vegetation, access, the detail and accuracy you need, the number of control points and the deliverables, such as CAD drawings, contours or a GIS dataset. A drone survey adds flight permission and processing. We confirm scope and deliverables in a written quote.
For open areas, a drone survey with well-placed ground control can come close to ground survey accuracy while capturing far more detail. Ground methods remain better for boundary pins, setting out and anything hidden under trees or roofs. Many projects combine both.
Yes. Drone flights need permission from the Civil Aviation Authority of Bangladesh (CAAB), and sites near airports, military areas or other sensitive installations may need further clearance. We prepare the application with the site details you provide, so allow time for approval in your program.
