Based at RAF Wyton in Cambridgeshire, 42 Engineer Regiment (Geographic) is the British Army's dedicated geospatial intelligence unit. Co-located with the National Centre for Geospatial Intelligence (NCGI), the regiment is responsible for delivering critical location-based data, terrain analysis, and digital mapping to commanders at all levels, from the strategic headquarters to the soldier on the ground. It is a hybrid unit comprising both Regular and Reserve personnel, with key sub-units including 13 and 14 Geographic Squadrons and the reserve 135 Geographic Squadron, all manned by specialist "Geo Techs." The regiment operates advanced high-tech systems to process satellite imagery and survey data, playing a vital role in everything from combat mission planning to disaster relief operations, notably providing the data modeling for the UK's COVID-19 response.
