About GeoHistoric

GeoInformation Historic Ltd was established in 1998, as a subsidiary  of The GeoInformation Group Ltd, specialising in historical sources and their application to innovative geospatial solutions. With the sale of the parent company to Verisk inc in 2016, the company became a dormant independent entity, until it started trading in 2020 as GeoHistoric.
Dr Seppe Cassettari was CEO of The GeoInformation Group and Chris Going was formerly Managing Director of GeoInformation Historic. They are now partners in the newly launched GeoHistoric.

Our backgrounds

Dr Seppe Cassettari

Seppe has over 40 years experience in the mapping and geospatial industry. Having recently retired from his role running Geomni UK, he is now working part time as a consultant and training specialist.

His career started with the UK military where he worked for 10 years in various mapping and geo-intelligence roles, during which time he completed one of the UK’s first PhDs in GIS. He then went on to run the ground breaking GIS undergraduate programme at Kingston University before being head hunted to run Longman GeoInformation for the publishers Pearson.

Following a management buy-out he became CEO of The GeoInformation Group in 1998 which went on to publish geospatial datasets and undertake many projects in the UK and abroad. The company is best known for the early aerial imagery databases developed in the mid 1990’s, published as Cities Revealed, and more recently the UKMap large scale topographic map base and the UKBuildings database of building type and age. The company also created the telecoms clutter data used by many mobile operators in the UK. The GeoInformation Group was sold to Verisk Inc. in 2016.

Seppe continues with his interest in mapping, writing regularly for the GeoConnexions magazine and being involved in the British Cartographic Society.

Since his time at Kingston University, Seppe has published many articles, books and papers and continues his contribution to the subject area through various publications. A selection of his industry leadership activities and publications can be found at the link below.

Chris Going

Chris Going graduated with a joint honours degree from the University of Wales (UCNW) in 1976 and worked as an archaeologist, initially with the Board of Celtic Studies, Cardiff, before joining archaeological field Units in his native Essex working principally with the Chelmsford Archaeological trust.

After moving to Cambridge in 1990, he undertook project and consultancy work with English Heritage, and the Central Archaeological Unit. During this time, he further developed long standing interests in aerial archaeology and landscape archaeology, becoming an executive member and sometime chair of the National Association of Air Photo Libraries (NAPLIB), consulting during this time to Academic and other organisations with substantial archives of aerial imagery. From the mid-1990s he brought his work more up to date by developing methodologies for the creation of UXO/EROW (explosive remnants of war) ‘peril maps’ becoming latterly a Director of Cambridge Architectural Research (CAR Ltd) where he carried out projects on EROW mapping in the Netherlands and Italy. 

In 2000 he joined GeoInformation Historic, then a subsidiary of the GeoInformation Group, as Director, where he developed ways of using archived aerial imagery more commercially. At the same time, with then Group CEO Dr Seppe Cassettari, he came up with unique ways to characterise UK and oversees building stock. This continues to be an active area of research.
