TMF recognizes that geographic information systems (GIS), global positioning systems (GPS) and remote sensing are essential techniques and tools for modern natural resource managers. GIS is a computer system that allows for the collection, storage, manipulation and visualization of data related to positions on the Earth’s surface while GPS is a system of satellite navigation that allows precise recording of where objects occur on the earth. Remote sensing is the process of monitoring the characteristics of the earth using different sensors such as satellites or airborne platforms.  Together, these systems provide valuable information and decision support to natural resource practitioners. TMF has been organizing and instructing GIS, GPS and remote sensing trainings for over two decades to multiple natural resource organizations in East Africa. In addition, TMF has provided GIS and GPS software and equipment to natural resource organizations, professionals and graduate students. By building GIS, GPS and remote sensing capacity at organizational levels, TMF supports long-term use and application of these tools and skills to improve the management and conservation of natural resources in East Africa.
