A quick hello from your newest member (Steve Walsh) I now have my feet under the desk at Aberystwyth and look forward to working with you all. I will try and keep up regular blogs on developments….

I had a meeting with Jonathan Brownett yesterday and got some very useful insights into the use of spatial data from the coal face …….Below is a brief summary of Jonathan’s section of the project’s case study.

Jonathan Brownett – IGES MSc student 

Project 

 Jonathan is looking at land cover change in the Dyfi Catchment over an 8 year period using a mixture of data from LANDSAT 7 and field parcel data (LPIS) from the Welsh Government. He has also made use of the Digimap service to access OS MasterMap data and elevation and shape file data accessed from within from IGES. 

Jonathan is then relating this data to the relatively new Land Cover Classification System (LCCS) which uses pre defined classifiers that can be applied to a level of detail suitable for a particular project. With this method he should be able to track changes in 20 or so categories of vegetation, bare land and water covered areas. 

Combined with some confirmation of actual ground cover species Jonathan should then be able to describe some of the major land cover changes  that have happened in the Dyfi catchment (very similar in extent to the Dyfi Biosphere area). 

He is well underway with his work and should have his data analysed buy the end of July and should receive some expert help in using LCCS from Lucile who will be visiting the Department from France and will be bringing her expertise in carrying out LCCS ground survey to the Dyfi Biosphere area. 

Relevant experience for the IGIBS case study 

In several ways Jonathan is a very useful case study as he has recently come from a Conservation BSc and has experienced GIS and Remote Sensing courses and the functioning of an SDI in two academic departments. With his MSc thesis he is now   discovering the intricacies of accessing data from external agencies and discovering the wealth of data held by individual researchers with their own approaches to metadata creation. He is also being forward thinking and has suggested that some of his data might be suitable to use for undergraduate teaching so suggested that he will discuss the best way to make available the research data he has generated with his supervisors.
