I am a GIS and Web Mapping Specialist and have been at BAS since 2016.  My role involves preparing content for GIS services including an internal GIS for BAS polar operations (as operations contact within MAGIC), an FCO environmental GIS add.antarctica.ac.uk and other related systems.  I maintain the UK Antarctic Place-names Committee gazetteer and web-map and develop the underlying geospatial information for Antarctic place names through defining spatial extents for gazetteer features from satellite imagery and other sources.  Additionally, I prepare maps for BAS polar operations and FCO Polar Regions Department and carry out similar work on other MAGIC projects.

Before coming to BAS I completed a BSc (Hons) degree in Geology at the University of St Andrews and a master’s degree in Geoinformation Technology and Cartography at the University of Glasgow.  During my undergraduate degree I worked with the University of Leicester in conjunction with British Geological Survey to assess the potential of Object-based Image Analysis to geological mapping.  My master’s thesis focussed on developing a method to assess changes in Siberian thermokarst lake dynamics over time using GRASS GIS and image classification techniques with SPOT satellite imagery between 1986 and 2010.
