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.

Exegesis developed a new mapping system to display marine spatial data, consisting of a web interface for configuring the mapper and a modern and feature-rich web application for displaying maps.

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.

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.

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.

Exegesis were contracted to undertake a review of Spartina anglica in England’s Natura 2000 Sites. This covered its impacts on designated features, effects on accretion and erosion, distribution and extent, and a review of control techniques. A protocol was developed to monitor S. anglica and help identify any negative impact.

exeGesIS were contracted to investigate the distribution of non-native species on protected sites in England, to help develop a programme of work to tackle Invasive Non-Native Species. Large scale data analysis was used to determine which protected site each species occurred within. We also reviewed data flow within Natural England.
