Unmanned Aerial Vehicles

UAV and Remote Sensing Services

Roy Northern owns and operates a fixed wing Unmanned Aerial Vehicle (UAV), commonly known as a ‘drone’. The UAV system is an unmanned aircraft; a small robotic plane with sensors on-board to collect high-resolution remote sensing data with minimum effort that provides invaluable, real-time data for various applications such as land surveying, agriculture, oil and gas, mining, security, forestry, chemical, and field conditions.

Satellite imagery on the other hand provides similar applications but for wider areas with less resolution (30cm to 10m). Natural color, infra-red vision, multi-spectral for analysis can all be customized to meet client’s environmental, land, archaeology analysis or image-mapping task needs.
