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.

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 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.

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 developed a methodology for monitoring Green Infrastructure (GI) delivery based upon Natural England's existing Integrated Site Assessment methodology. This encompassed ecology, access, green roofs and other aspects of GI delivery.
 

The observations and vegetation mapping module for CMSi was developed to allow managers to integrate wildlife records and vegetation surveys with their site data. This covers site monitoring projects, incidental records, data browsing and filtering, and includes a sophisticated report wizard.

We developed a condition monitoring methodology to gain an insight into and monitor the condition of non-statutory woodlands. The survey methodology was tested on 100 sample sites. The main outputs were a woodland condition assessment manual, survey database, regression analysis, project report and baseline condition data.

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.
