Drone-Based Topographic Survey for Ashulia Model Town

Project Name: Ashulia Model Town
Location: Biralia, Savar Upazila, Dhaka Division
Client: Amin Mohammad Lands Development Ltd.
Project Area: 10.00 SQKM
Project Title: Drone-Based Topography Survey, C.S, R.S, and City Mouza Map Adjustment

Project Overview

Amin Mohammad Lands Development Ltd., a renowned real estate developer in Bangladesh, entrusted us with a comprehensive Drone-Based Topographic Survey for the Ashulia Model Town project. This large-scale land development project, located in the Biralia region of Savar Upazila under the Dhaka Division, spans approximately 10 square kilometers.

Our specialized survey team delivered a highly detailed and accurate GIS-ready spatial dataset, combining drone technology with conventional survey methods to support urban planning, infrastructure development, and cadastral mapping.

Scope of Work & Responsibilities

Our team executed a wide range of tasks to ensure complete and precise data acquisition, processing, and deliverables:

TBM Installation and Static GPS Observations:
Established permanent benchmarks with static GPS observation for accurate georeferencing and elevation data.
Drone-Based Aerial Survey:
Utilized Mavic 3 Enterprise drones to capture high-resolution aerial images for producing orthophotos and digital terrain models.
Mouza Map Field Location Collection:
Conducted on-ground verification and geolocation of Mouza boundaries for C.S, R.S, and City Survey maps.
Ortho-Mosaic Digitization:
Processed aerial imagery using DJI Terra to generate high-quality ortho-mosaics, which were then digitized for map production.
C.S, R.S, City Mouza Map Digitization:
Scanned, rectified, and digitized cadastral maps aligning with national coordinate systems.
Joint Line Refinement of Mouza Maps:
Enhanced boundary accuracy through detailed line adjustments, field verification, and georeferencing.
Integrated Pentagraph Mapping:
Created a combined representation of the entire project area, integrating C.S, R.S, and City Survey maps with field data.
GIS & CAD Deliverables:
Delivered final datasets in both GIS shapefile and AutoCAD (DWG/DXF) formats for versatile usage in design and planning workflows.

✅ Benefits of Drone-Based Topographic Survey

Drone-based topographic surveys offer a modern, efficient, and highly accurate alternative to traditional land surveying methods. Whether for urban planning, infrastructure development, or large-scale land assessment, this technology provides several key advantages:

1. High Accuracy and Detail

Drones equipped with high-resolution cameras and GNSS/GPS capabilities can capture precise elevation data and surface features, allowing for the creation of detailed Digital Elevation Models (DEMs) and orthophotos. This results in centimeter-level accuracy that is ideal for engineering, design, and planning applications.

2. Time Efficiency

Compared to conventional ground survey methods, drone surveys are significantly faster. What would take days or weeks with traditional tools can be completed in just a few hours or days using drones—saving both time and cost for large-scale projects.

3. Cost-Effective

Drone surveys reduce the need for large survey crews and expensive field equipment. The ability to quickly collect data over vast and difficult terrains means lower labor costs and fewer site visits, making it ideal for budget-conscious projects.

4. Access to Hard-to-Reach Areas

Drones can easily fly over challenging terrains, such as hills, rivers, forests, or construction zones, where manual surveys are risky or impossible. This ensures complete data collection without compromising safety.

5. Visual Documentation

Drone-captured imagery offers a real-time visual overview of the site. These visuals help stakeholders understand site conditions, monitor progress, and make data-driven decisions using up-to-date images and videos.

6. Integration with GIS and CAD

Drone survey outputs are compatible with popular software platforms like ArcGIS, AutoCAD, and Civil 3D. This enables seamless integration into existing workflows for map creation, design layouts, and analysis.

7. Improved Project Planning & Decision Making

By providing quick, reliable, and high-resolution data, drone surveys empower architects, engineers, and planners with better insights, leading to faster decision-making and more accurate project designs.

8. Environmentally Friendly

Drone-based surveys minimize environmental impact by reducing ground disturbance, vehicle usage, and manual intervention—making them a greener choice for sustainable development.
