Derrick Koome is a holder of a Bsc (Geospatial Engineering) from University of Nairobi. He briefly worked in a busy Geospatial firm in Nairobi (Nile Surveys and Geo-solutions) and by the time he left was its Chief Surveyor. He started his own land survey practice soon after (Cheswick Surveys) which is based in the outskirts of Nairobi, Kenya. Derrick is a live wire with use of geodetic GPS and Total Stations as well as all the geometric calculations and software involved. When his eye is not behind a telescope he loves to write articles about survey. One of these articles was republished in an Australian magazine. When he’s not working, he loves to go for excursions, watch Liverpool play and drown the occasional beer like all good surveyors do.
