� Sample survey for agriculture, forestry, geophysics
4) Technology
Airborne survey system provides the aerial survey and remote sensing
industry with a revolutionary method of georeferencing data. Direct Georeferencing is
the direct measurement of sensor position and orientation (also known as the
exterior orientation parameters), without the need for additional ground information
over the project area. These parameters allow data from the airborne sensor to be
georeferenced to the Earth or local mapping frame. Examples of airborne sensors
include: aerial cameras (digital or film-based), multi-spectral or hyper-spectral
scanners, SAR, or LIDAR. All Airborne survey systems integrate seamlessly with the
Air Flight Management System.
5) Application capability:
1. Aerial Camera Systems (Film Camera)
• Topographic mapping
• Producing 23cm square
• High resolution color, color infrared
• Aerial film cameras have been a standard
• Gyro-stabilized mounts, and various navigation
• Aerial film cameras are an efficient and complete photographic unit.
• Orthophoto production
2. Aerial Camera Systems (Digital Camera):
• Designed around CCD (Charged Coupled Device) imaging
• uses radiometric pixel resolution to generate standard perspective,
• high-resolution digital imagery. Producing four color channels in
• red, green, blue, and near-infrared, projects can now be
• undertaken in low light conditions with excellent results.
• Topographic mapping
• DTM (Digital Terrain Model) generation
• High-resolution digital imagery
• Orthophoto production
• Resource industry volumetrics
