The aerial photogrammetry products of First Aero Survey Co.,Ltd. Are utilized in Naver Maps and V-World 3D maps, and are also essential data in various fields such as map production, various surveys, planning, and military operations.
Recently, we have secured and applied precision spatial information construction technolohy through the establishment of spatial information using drones and the development of drone shooting management systems.

We support various services, by building national spatial information
through aerial surveying of the entire country -
-
Digital Aerial Photogrammetry
Rapid and effective surveying for large areas
-
- Capable of capturing and surveying with resolution sufficient to identify objects as small as 8cm, even at high flight speeds
- Suitable for photogrammetry, remote sensing, and cadastral mapping, which require extensive data processing
- Applicable to various spatial analyses, such as information identification and 2D/3D mapping with excellent image quality across all spectral bands
-
Drone Surveying
Highly mobile with the capability for high-quality imaging and surveying
-
- Up to 1.98km² can be captured and surveyed in a single flight (eBee RTK)
- Orthophotos with an accuracy of ±5cm can be generated without ground control points or aerial targets(eBee RTK)
- Available to acquire specific ground coordinates through sensors in environments where GPS cannot be used (DJI Inspire 1)
-
Multi-Directional simultaneous imaging(CityMapper)
Optimized for 3D spatial information generation through five-directional simultaneous imaging
-
- Simultaneous imaging of the ground in east, west, south, north (at 40° angles), and vertical directions enables optimal 3D spatial information generation
- With proprietary software, it is possible to measure the area, height, width, distance, and angles of buildings in photos without any additional data
-
Aerial LiDAR Surveying
Use for disaster, earthquakes, exploration of historic sites, etc
-
- Measure terrain and vegetation size using laser pulses
- Generate Digital Surface Models (DSM) and Digital Elevation Models (DEM) from acquired data
- Applicable to disaster analysis, exploration of inaccessible terrains, active fault lines related to earthquakes, heritage sites, and various other applications
