A traditional survey measures selected points on the ground with a total station, GNSS receiver or level, and records them as plans and contours. A drone aerial survey flies a UAV over the site, captures overlapping images or laser data, and processes them into maps, elevation models and 3D data that cover the entire surface. […]
What is Drone Aerial Survey? Process, Equipment & Uses
A drone aerial survey uses an unmanned aerial vehicle (UAV) fitted with a camera or LiDAR sensor to capture overlapping images or laser data of land from the air. The data is processed into georeferenced outputs such as orthomosaic maps, elevation models, contours, 3D models and volume reports. It is faster and safer than manual […]

When comparing LiDAR vs drone survey in Imphal, the right choice depends entirely on your site’s terrain. If your project sits on Imphal’s open valley floor, in the city, or on farmland, a drone survey in Imphal is the faster and more cost-effective choice. If your project is located on the forested hill ranges […]
Photogrammetry vs LiDAR: Key Differences Explained
Photogrammetry vs LiDAR: What’s the Difference & Which Does Your Project Need? Every survey project starts with one question: how do we capture the site accurately? Two technologies dominate this decision today — photogrammetry and LiDAR survey. Both create 3D maps of land, buildings, and infrastructure, but they work in very different ways and suit […]
