Elevation models and orthophotos in Africa

Topographic data for mining and railway infrastructure

Back

In 2007, BSF Swissphoto has been mandated by Arcelor Mittal Mining Senegal as well as Mittal Steel Liberia with several airborne data acquisition projects in Africa.

Using airborne laser scanning, BSF Swissphoto produced detailed digital surface and terrain models for an area of 500 km2 in Liberia and of 1400 km2 in Senegal. In both areas, iron ore mining operations have been launched.

In addition, more than 700 kilometers of projected railway lines providing access to the remote mining sites were surveyed. Besides the elevation data, digital orthophoto mosaics with 20-25 cm ground sampling distance were produced.

Aerial survey operations in remote areas on the African continent pose a number of challenges regarding flight permissions, (fuel) supply logistics, climate and foliage – all of which were successfully overcome to deliver the required products to our clients.
