Andrew Terhorst started his career in 1984 at the Institute for Maritime Technology, Simon's Town, South Africa. He lead a project to map the seabed in a proposed torpedo test range. The results of this mapping exercise were written up as a MSc dissertation. Andrew joined De Beers Marine in 1987 where he worked as an Exploration Geophysicist. He was tasked to use sonar imaging and shallow seismic techniques to highlight marine diamond deposits. This included going to sea to supervise the collection of marine geophysical data and shore-based processing. Andrew was also tasked to explore new methods for marine geophysical survey and played a key role in the introduction of advanced spatial information technologies. He left De Beers in 1991 to start his own business "TerraMare Remote Sensing" (later renamed "TerraMare Environmental Data Systems"). The business started out doing exclusively remote sensing data processing and analysis but as it grew, it evolved into a Geographic Information Science (GISc) consultancy that served a broad range of local and international customers in the fields of environmental assessment, forestry management, hydrology/geohydrology, mining and exploration, nature conservation, nuclear energy generation, and urban and regional planning. Andrew worked as an independent GISc consultant between 2002 and 2004 before joining the CSIR as Earth Observation Manager at the Satellite Application Centre. He developed a passionate interest in Sensor Web Enablement and moved across the Meraka Institute (African Advanced institute for ICT) in 2005 where he established a research group known as "ICT for Earth Observation". The core activities of this group were evaluation of emerging standards for Sensor Web Enablement and research and development of knowledge services for Earth Observation. Andrew left the CSIR in 2007 to take up a position with the CSIRO ICT Centre in Hobart, Tasmania. He is currently leading and engaged in research into real-time environmental situation awareness, leveraging standards for Sensor Web Enablement and Linked Open Data.
