Exegesis Spatial Data Management

Over several years exeGesIS undertook a number of analyses of Greenspace provision, comparing the results against the standards in the CCW Greenspace Toolkit. Analysis was undertaken to determine the distance between each postcode and the nearest access point on the nearest Greenspace.

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.
 

Various datasets relating to the rights of way management in Rhondda Cynnon Taf had fallen out of date, and exeGesIS was asked to assist Rhondda Cynnon Taf County Borough Council with the task of updating and correcting this information, using data from multiple sources to do so.

exeGesIS built comprehensive and consistent greenspace datasets. This dataset was used to assess whether greenspace targets were met. Network analysis techniques were employed to ensure the shortest walking distances from every postcode area, to the nearest greenspace could be identified and measured.

exeGesIS built the River Basin Management Planning System (RBPMS): an integrated MapInfo Professional and web-based mapping tool. This collated, analysed and presented data in order to simplify the consultation process that the EU Water Framework Directive required.

exeGesIS were commissioned to produce a digital map of Greenspace for East Lothian, Midlothian and Aberdeenshire County Councils. MasterMap data were classified to a standard land use classification using attributes and aerial photograph interpretation. These data were provided as a single Greenspace dataset.

We collated and processed existing digital information to determine the sustainability of Motorised Recreational Vehicle routes. 'Noise' and 'tranquillity' maps were created for the Cambrian Mountains region. Several hundred kilometres of routes and roads were surveyed to record the physical robustness and condition of vehicular routes.

exeGesIS provided data collation, analysis and reporting services for a national project researching access to water-based recreation facilities across the UK. Water resource datasets were compiled and were subjected to network analysis to determine the accessibility of water resources.

exeGesIS were contracted by Plantlife Cymru to help with the identification of computer based methods and techniques suitable for defining and mapping Important Plant Area (IPA) boundaries. We demonstrated how spatial analysis techniques can be used to define IPA boundaries and how areas of potential IPA expansion can be modelled and visualised using GIS.

Devon County Council asked exeGesIS to calculate the gradients along their Rights of Way network. This would inform decisions about accessibility and the availability of the network for different users, and particularly targeting resources in order to improve accessibility.
