Exegesis Spatial Data Management

exeGesIS were contracted to undertake a feasibility study on the development of a tool to assess functional ecological connectivity. This involved an assessment of user needs, a review of the available methods and approaches, a stakeholder workshop to identify the preferred options and the development of a functional specification.

exeGesIS analysed Marine Intertidal Phase 1 data for the whole of Wales using the standard CCW Conservation Assessment Protocol and a bespoke database application in Microsoft Access. This application reads and analysis the original survey data to produce reports containing the results, measured against SSSI selection criteria.

exeGesIS has produced habitat inventories for coastal vegetated shingle, saline lagoons, grassland and upland Biodiversity Action Plan (BAP) habitats. These involved collating spatial data, capturing paper-based data, aerial photograph interpretation, ground truthing and processing available data to create standardised national datasets.

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.
 

The MESH project gathered large amounts of marine habitat data from a number of European partners. These were standardised to produce a unified seabed habitat map using the best data available for each area. We produced web mapping for this project using open source Mapserver software.

exeGesIS used a GIS model to predict the effects of disturbance from visual stimuli on nesting stone curlew Burhinus oedicnemus. This was used to map and graph the effects of different disturbances on the birds and identify the best areas to undertake habitat management to encourage nesting.
