CTK Network Aviation was initially established to provide aerial photography, digital mapping and related services to customers in Ghana and West Africa. We provide these services in co-operation with the Grontmij Group under the name Grontmij Aerosat Surveys Ltd. This Dutch multinational has more than 85 years of experience as an engineering consultancy firm in the fields of soil and water management, spatial planning, construction, infrastructure and telecommunications. It has about 4,300 employees, and is listed on the Amsterdam stock exchange.

Over the past ten years CTK has acquired trained personnel and state of the art equipment to produce high quality digital maps from aerial photographs. We are well-equipped to carry out ground surveys, where we measure coordinates of features on the ground to geo reference our digital maps. Furthermore we can add value to the digital maps we produce by enriching them with digital information, resulting in state of the art Geographic Information Systems (GIS).
