01What is a topographic survey?

A topographic survey records the natural and man-made features of a site — ground levels, slopes, buildings, roads, watercourses, trees, walls and utilities — along with their precise positions and elevations. The result is a detailed plan and 3D model used for site design, drainage, earthworks, planning permission and construction setting-out.

02How MKA Mesh Systems delivers your survey

• Ground control — we establish survey-grade GNSS control points (RTK/PPK) tied to your coordinate system for verified accuracy.
• Data capture — drone photogrammetry and/or LiDAR capture dense, accurate data across the whole site, supported by total stations where needed.
• Processing — imagery and point clouds are processed in Pix4D, Agisoft Metashape and Global Mapper into clean, classified datasets.
• Quality assurance — every deliverable is checked against control with a documented accuracy statement.

03Deliverables

• 2D topographic plans (DWG/DXF) with levels and contours
• 3D surfaces / TIN models and digital terrain models (DTM/DEM)
• Contour maps at your chosen interval
• Orthomosaic base maps and point clouds (LAS/LAZ)
• GIS layers (SHP/GeoPackage) and control/accuracy reports

04Applications & industries

Road and highway design, building and infrastructure projects, drainage and flood studies, mining and quarrying, land subdivision and cadastre, urban planning, and agriculture. Wherever you need to know the exact shape of the ground, a topographic survey is the foundation.

05Accuracy you can build on

With proper ground control, our drone topographic surveys typically achieve 2–5 cm horizontal and vertical accuracy — meeting the requirements of most engineering and construction projects while covering far more ground per day than walking the site with a total station.

06Frequently asked questions

How much does a topographic survey cost in Cameroon? Cost depends on site size, terrain, required accuracy and deliverables. Drone surveys are usually significantly cheaper per hectare than traditional methods. Contact us with your site details for a tailored quote.

How long does a topographic survey take? A typical site can be flown in a single day, with processed deliverables in a few days. Large or complex sites take longer.

What format are the deliverables? We supply CAD (DWG/DXF), GIS (SHP/GeoPackage), point clouds (LAS/LAZ) and PDF plans — whatever your design team needs.
