The Peak District National Park Authority has had access to the HER data of the five constituent local authorities, stored in separate HBSMR databases, for nearly ten years. In order for the National Park Authority to maintain SHINE (Selected Heritage Inventory for Natural England) data within the Park a merged dataset was required.

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.

Exegesis undertook an aerial survey of a site and orthorectified and mosaicked the imagery to create a single image. We also generate a digital surface model, which was compared against lidar data to give the change in height. We then determined the volume of additional material within patches identified from the aerial photography.

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 and Natural Resources Wales (NRW) undertook a 1,200 km survey of the Wales Coast Path prior to its opening. This was used to establish a baseline for the condition of the path and provide a resource for those responsible for its management. exeGesIS worked with NRW to establish the methodology for the survey.

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 undertook an analysis of Greenspace and Public Open Space in Carmarthenshire for 21 major and 51 minor settlements to determine the percentage of the population in each settlement which passed set criteria. The results were reviewed by local authority staff via a website, allowing comments to be left and read by others.

Over several years exeGesIS undertook a number of analyses of Greenspace provision, comparing the results against the standards in the CCW Greenspace Toolkit. Analysis was undertaken to determine the distance between each postcode and the nearest access point on the nearest Greenspace.

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.
