Exegesis Spatial Data Management

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.

exeGesIS collated maps of Green Infrastructure (GI) delivery and captured the information. Areas of UK priority habitats and other GI were separately mapped and attributed. In total, 753 cases were mapped amounting to 3,485 polygons (21,342 ha).
 

The objective of this project was to process licence data from their legacy database to improve the accuracy of the spatial information. This was completed using a series of data validation rules.
 

Exegesis upgraded the National Bat Monitoring Programme (NMBP) recording system to SQL Server with an accompanying website that allows volunteers to record their roost counts online. The website includes recording forms, mapping and administration pages as well as an Access administration client.

As part of their annual maintenance scheme Powys County Council requires a condition survey carried out on a 5% sample of the Rights of Way network, in line with established BVPI (best value performance indicator) standards.
 

Ceredigion County Council required a condition survey carried out on a 5% sample of the Rights of Way network. exeGesIS undertook the survey, analysed the condition data and produced reports. The data was also imported into CAMS in order to make it accessible to all officers responsible for the network.

exeGesIS worked closely with Natural Resources Wales prior to the opening of the Wales Coast Path to provide a digital copy of the path for reference and release to the public in a variety of formats. The task required splitting and labelling approximately 1,500 km of path network supplied by NRW.

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.

This project involved the collation and evaluation of a suite of ecological datasets, the production of an indicative map of upland habitats, an investigation of upland field data collection options, and capturing all survey data to GIS.
