We created a hedgerow map for the Gower based upon Ordnance Survey MasterMap and aerial photograph interpretation. The resulting dataset contained 22,370 features of which 17,013 were thought to be hedges.

Exegesis were contracted to create and refine a complete provisional inventory of Open Mosaic Habitat (OMH) in England. We used a combination of available data sources and aerial photograph interpretation to accurately map possible OMH, also capturing information on the confidence that OMH was present.

Exegesis investigated the options for creating an Annex I habitat inventory for England. This involved a review of approaches taken by other European Union countries and the data available in the UK. A recommended approach was suggested, along with the provision of prototype inventories to show potential coverage.

We identified the key features and enhanced knowledge of the distribution of UK BAP Open Mosaic Habitats on Previously Developed Land. This involved the development of a survey methodology and a survey of 98 sites to identify OMH habitat, including a survey of invertebrates on 50 - the largest single survey of its kind in the UK.

Over a series of projects exeGesIS created a spatial inventory of wood pasture and parkland in England. Data were assessed against historic maps and aerial photography, as well as modern data sources. Ground truthing was undertaken in two regions. The resulting inventory mapped 156,838 ha of wood-pasture and parkland.

exeGesIS has produced habitat inventories for coastal vegetated shingle, saline lagoons, grassland and upland Biodiversity Action Plan (BAP) habitats. These involved collating spatial data, capturing paper-based data, aerial photograph interpretation, ground truthing and processing available data to create standardised national datasets.

exeGesIS produced an updated map of ancient woodland in Wales . Woodlands were mapped according to forest type determined from aerial photographs. The resulting dataset was more compatible with other rural land-use datasets, such as the agricultural Integrated Administration and Control System.

The Pond Conservation Trust commissioned exeGesIS to develop a database for pond survey data, recruit information of relevance, create an inventory of ponds in the UK, enable online collection of pond information from members of the public and present pond information online.

exeGesIS developed data input and verification software that could be run from within the user's standard GIS interface. This ensured that English Nature's habitat inventories could be amalgamated quickly and efficiently, and standardised the data attributes. Support and training for the system was provided by exeGesIS.
