Aerial Mapping

RGC has an impressive history of successful aerial work carried out in over 15 African countries under often difficult circumstances. RGC offers several platforms for aerial surveys, fixed wing, helicopter and drone. This affects the time and cost of a project. RGC can tailor make projects to suit the client’s needs and budget.


RGC works closely with CK Aerial Surveys (a subsidiary of Tallow Africa Limited) out of a base in Johannesburg, operating two airborne survey systems, comprising LiDAR and integrated medium-format cameras.

The Leica ALS80 LiDAR system is the current state-of-the-art LiDAR system from Leica Geosystems. It offers a scan rate of 1 million points per second, which yields point densities up to five times that of older generation LiDAR systems.

In addition, the 4-band 80-megapixel Leica RCD30 camera flown in conjunction with the LiDAR system, yields full-colour and near-infrared geo-referenced orthophotos at very high resolution. Furthermore, for projects requiring the highest possible resolutions in the optical spectrum, the twin-camera system from Phase One, comprising two 3-band 100-megapixel cameras is available.


RGC works closely with Mathias Kaden from from Kaden Surveys in Potsdam Germany. Kaden Surveys specialises in both monitoring of construction projects and large scale drone surveys world wide.
