Exegesis Spatial Data Management

Exegesis were appointed by Natural England to compile a national HLC dataset, drawing together the existing sub-regional HLC datasets and applying a common framework, structure and terminology to a new unified dataset. The aim of the project is to improve the awareness, understanding and ability to manage and monitor England’s historic landscape at a national scale.

exeGesIS successfully incorporated the changes made by over 140 public path orders into the digital map layer, and linked the scanned order files to records in CAMS. This provided the client with an effective, efficient tool to help manage their rights of way.

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.

We demonstrated through spatial processing and statistical analysis that it may be possible to predict wood pasture and parkland quality. This project generated a model that could be used to target survey effort to those sites with the highest predicted quality.

JNCC contracted Exegesis to undertake a review comparing the functionality available in ArcGIS with that in QGIS. Nearly 1,000 items of functionality were reviewed to ascertain whether they occurred in QGIS. We also assessed the required changes to JNCC’s IT infrastructure in order to implement QGIS, as well as the associated costs.

The Wales Active Travel Act required Local Authorities to produce a map of safe footpaths and cycle-ways. We provided a web-mapping solution for the collation and management of this information.

This desktop application imports archives from the UKDMOS database into SQL Server and converts the spatial data into SQL geometry layers. It creates layers that can be used by JNCC when assessing the extent of UK marine monitoring according to each broad marine discipline (e.g. biodiversity, physical oceanography and fisheries).

The Archbishops’ Council Faculty Simplification Group commissioned a working party to make recommendations for modernising and streamlining the faculty system. As part of this endeavour, ChurchCare - the Church of England's national resource - together with Exegesis, developed the Church Heritage Record and Online Faculty System.

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 quickly and efficiently standardised existing polygon data to MESH Translated Habitat DEF using a range of tools within ArcGIS, QGIS, GRASS and MapInfo. We also imported survey data into Marine Recorder following expert analysis of the data to determine biotopes.
