LiDAR Airborne Mapping

What is LiDAR Airborne

Airborne LiDAR is a remote sensing method where laser sensors are mounted on aircraft or drones to scan the Earth’s surface. This technology collects accurate elevation and surface data quickly and efficiently, even over large or remote areas.

In Malaysia, airborne LiDAR mapping is widely used for topographic surveys, infrastructure planning, flood risk analysis, forest monitoring, and coastal studies. It is especially useful in terrains that are difficult to access using ground-based survey methods.

At Geotechnica, we offer airborne LiDAR services in Malaysia using high-precision equipment and certified geospatial professionals. Our LiDAR data supports faster project planning, detailed 3D models, and informed decision-making for various industries.

FAQ

LiDAR Airborne FAQ

What is airborne LiDAR and how is it used in Malaysia?

Airborne LiDAR is a remote sensing method using aircraft or drones equipped with laser sensors to scan the Earth’s surface. In Malaysia, it’s commonly used for topographic mapping, flood risk analysis, coastal studies, and infrastructure planning.

Difference between airborne LiDAR and drone-based LiDAR?

Both use laser scanning technology, but airborne LiDAR typically refers to systems mounted on aircraft, suitable for large-area surveys, while drone-based LiDAR is used for smaller or more complex sites. Geotechnica provides both depending on project scale and accuracy requirements.

How accurate is airborne LiDAR mapping in Malaysia?

Airborne LiDAR mapping in Malaysia can achieve vertical accuracy within 5–15 cm, depending on flight height, terrain, and sensor type. It’s highly reliable for creating Digital Terrain Models (DTM) and elevation data for engineering-grade projects.

What types of projects benefit from airborne LiDAR in Malaysia?

Projects involving large-scale terrain mapping, urban development, coastal monitoring, forest management, and mining operations can greatly benefit from airborne LiDAR technology in Malaysia.

Can airborne LiDAR be used for flood risk modeling in Malaysia?

Yes. Airborne LiDAR Malaysia is ideal for generating elevation models that support hydrological analysis, catchment mapping, and floodplain delineation, helping authorities and engineers plan effective mitigation strategies.

Is airborne LiDAR suitable for forested and remote areas in Malaysia?

Absolutely. Airborne laser scanning can penetrate dense tropical vegetation, making it perfect for mapping forest floors, monitoring biodiversity, and conducting plantation surveys in Malaysia’s remote or rugged areas.

What deliverables are produced from airborne LiDAR surveys?

Typical outputs include:

1. Digital Elevation Models (DEM)
2. Digital Terrain Models (DTM)
3. Point clouds (LAS/LAZ format)
4. Contours and slope analysis
5. 3D surface models for GIS and CAD platforms

How long does an airborne LiDAR survey take in Malaysia?

The duration depends on the size and complexity of the site. However, most airborne LiDAR surveys in Malaysia are completed within a few days, including flight, data processing, and report generation.

Is airborne LiDAR data compatible with GIS platforms?

Yes. At Geotechnica, we provide LiDAR outputs fully compatible with platforms like ArcGIS, QGIS, AutoCAD Civil 3D, and other engineering software used in Malaysia’s geospatial and infrastructure industries.

Why choose Geotechnica for airborne LiDAR services in Malaysia?
