In the last couple of days I have met with a number of people who have previously or are currently working on projects within the Dyfi Biosphere. I have asked what data sets they have available and what their requirements of this tool would be.

I have met with Anthony Smith, the map curator in IGES. He agrees that the IGIBS data and tool would be very useful for both students and staff. The data acquired would also add to and help to update the map library. It also seems that many data sets relating to maps within the library are actually held among various researchers within the department. This currently makes it difficult for anyone to locate data sets relating to catalogued maps. The use of Geodoc for metadata recording and management might improve this situation but ultimately the Dyfi Biosphere and IGIBS mapping application would make all the information available in one site.

Alisdair Cunningham is a PhD student and is studying and developing methods for detecting habitat and land-use change in Wales using remote sensing. He will be concentrating his research on the Dyfi Biosphere area. He has many data sets available for the use of this project which have now been collated and stored safely along with other lists of data we are accumulating. Alisdair has said the proposed IGIBS tool and mapping application would be very useful for his research as it would draw together data sets compiled by other researchers. It could also act as a place to store his data sets so that they are easy to access, view, and compare. He would particularly like to use the LiDAR data from the Dyfi Biosphere.

In the process of collating the data sets for this project we have acquired LiDAR data of the area from a Dr. Angela Harris who is a lecturer at Manchester University and has been researching the use of remote sensing in monitoring northern peatland hydrology. She has also provided hyperspectral data and aerial photographs which will be very useful for Professor Richard Lucas who is working on a BIOSOS project in the Dyfi Bioshere and again for Alisdair Cunningham’s PhD research.

Already this project is linking people and their data sets with each other and should eventually prove to be a valuable and expanding resource to all researching and learning about the Dyfi Biosphere.

Information is now being collated on available data sets to incorporate in this project. We have identified a number of case study users from the Institute of Geography and Earth Sciences (IGES), Aberystwyth University and Forest Research in Wales, Forestry Commission who have previously and are currently working on projects based in the Dyfi Biosphere.

As part of the process for gathering this information users are being actively encouraged to create dataset metadata using GeoDoc tool – found within the GoGeo area on the EDINA web site. This utility is used to create standards compliant dataset metadata for upload into catalogues, eg, GoGeo! so that the data can be discovered, evaluated and possibly reused. Note that you need to have UK Access Management credentials to use GeoDoc.

Users that we have identified so far consist of academics, researchers and students within IGES in Aberystwyth University, and from the Centre for Catchment and Coastal Research (CCCR) which is a consortium of Aberystwyth University and Bangor University. Users will also include researchers from Forestry Research in Wales, Forestry Commission and staff from the Countryside Council for Wales (CCW). Within these bodies individuals have been identified and we will develop these as user case studies. We are currently collating their data sets and identifying their relevant uses and needs.

In the following weeks we will collate and input data sets some of which are complete whilst others are work in progress. These data sets will come from the individual user case studies. The user case studies will be something like the following:
• IGES Academic/Researcher
• IGES/CCCR Academic/Researcher
• IGES MSc Student
• IGES PhD Student
• IGES Digital Map Librarian
• Forestry Research Researcher
• CCW Senior Reserve Warden for Dyfi Biosphere Area

A ‘shopping list’ of data sets that are either not currently available to these users (and which they would like access to) or are difficult to find will also be identified and collated. Already we have had requests for biogeochemical data sets from IGES/CCCR, and for remote sensing data sets from Forest Research. It is hoped that Welsh Assembly Government may be able to help with some of these data and that, even if their use is restricted, we may be able to offer access to using web services secured using Shibboleth (the software underlying the UK Access Management Federation).

So far we have identified from the academic/researcher evidence that both academic staff and students would find the Web Map Service (WMS) “factory” application useful as a research and teaching tool. It has also been suggested by one of the academic users that an undergraduate module could be developed around the use of open geospatial standards. It was agreed that using the GeoDoc metadata input facility would generally improve data management practice for research projects.

Any comments from the user case study individuals or other potential users would be much appreciated to ensure the relevant uses and needs of all involved in this project are identified. The information will feed into the development of the mapping application and the identification of future requirements.
