Exegesis Spatial Data Management

Exegesis were contracted to establish whether aerial imagery from UAVs could be used to investigate the spatial and temporal extent of bait digging at selected sites in Wales.

We developed a comprehensive online information management system and community hub for staff and volunteers involved in their Saving Scotland’s Red Squirrels – Developing Community Action project.

Exegesis was contracted to establish vegetation monitoring at a saltmarsh coastal realignment site. This required the collection of high resolution aerial imagery, quadrat based vegetation survey, mapping in GIS and production of a detailed report.

Exegesis was contracted to redevelop GiGLs online data mapping portal. This involved a radical overhaul of both design and functionality.

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 reviewed the data management processes used by the Saving Scotland’s Red Squirrels project to identify any problems or limitations and make recommendations. We also wrote a specification for an online Community Hub.

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.

We developed the BASC Green Shoots website, which is designed to encourage their members to contribute to biodiversity conservation by recording shooting areas, habitats and species they see.
 

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).

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.
