Case Study - CEH



The Centre for Ecology & Hydrology (CEH) is a public-sector research centre. Both it and British Geological Survey (BGS) are part of the Natural Environment Research Council (NERC) which delivers independent research, survey and training in the environmental sciences to advance knowledge of the Earth as a complex, interacting system.

CEH is a custodian of environmental data, including 20 million records of 12,000 species occurring across Britain and Ireland, as well as records of over 50,000 station years of daily and monthly river flow data, derived from over 1,300 gauging stations throughout the UK.


CEH decided 3D visualisation was ripe for investigation when Gwyn Rees, the director of the Environmental Information Data Centre at CEH, saw GeoVisionary at BGS.  As a result, CEH began using Virtalis’ GeoVisionary software to visualise its data in 3D.

“We are always looking for new and innovative ways to access, analyse and communicate our data.”
Gwyn Rees, the director of the Environmental Information Data Centre at CEH


GeoVisionary was developed by Virtalis, in collaboration with BGS, as 3D software for the high-resolution visualisation of elevation and photography data overlaid with a wide range of geospatial data.  One of the major advantages GeoVisionary offers over other visualisation software (3 & 4D GIS) is its ability to integrate very large volumes of data from multiple sources and interact with it in real time.


CEH has installed a VR suite, known as a Virtalis ActiveWall, in order to view GeoVisionary in 3D at its headquarters in Wallingford, Oxfordshire.  ActiveWall is an installed, immersive 3D visualisation system and probably the best selling VR system in the world.  CEH has also installed the desktop version of GeoVisionary at each of its other three offices in Bangor, Edinburgh and Lancaster, and has also a portable VR system, known as an ActiveMove, so it can take GeoVisionary on the road.


As well as using GeoVisionary to display hydrological, air quality and floral and faunal data in a user-friendly way, CEH is using it to plan fieldwork.  GeoVisionary is much clearer than a map, so by visiting a site in Virtual Reality (VR) first, the CEH team can check access, identify risk areas and give Health and Safety briefings.

“We’re seeking to exploit the capabilities of GeoVisionary on a variety of projects and have provided introductory training to some 40 staff.  Already, we’re finding that we are getting better insights from our data.  GeoVisionary also neatly encapsulates our work to visitors, really showcasing our science.  So far, we’ve used the system to see how land cover relates to terrain and cross referencing with Ordnance Survey and digital photography layers.  In another project, we are analysing the dispersal of plant species in one of our Environmental Change Network networks in the Cairngorms, GeoVisionary clearly shows how different species congregate in different parts of the terrain.  GeoVisionary is enabling us to derive new insights from our pre-existing data.  We are keen to use GeoVisionary on more applications and as a critical means of communicating our science to a wider audience.”
Gwyn Rees, the director of the Environmental Information Data Centre at CEH
