For the Dyfi catchment, the main datasets acquired by satellite and airborne sensors have been collated and a description provided, including dates, with this undertaken to support, in part, biodiversity and land cover change projects being conducted through IGES. Satellite sensor data available include Indian Remote Sensing Satellite (IRS), SPOT High Resolution Geometric (HRG), Landsat and Terra-1 ASTER. Airborne datasets available include LiDAR, hyperspectral data and aerial photography. Hugh Evans from Forest Research also visited to discuss options for postgraduate dissertation work in the Dyfi Biosphere over the next few months.
A number of datasets have now been identified and which may be put together within a centralised data store (where available). In particular, we have focused on the following:
a) Vegetation maps for the Dyfi catchment, within these including the Phase 1 Habitat Survey, the National Vegetation Classification (NVC), the Land Cover Map 1990 and 2000.
b) Soils datasets, including types.
c) Protected areas
d) Satellite sensor data, namely Landsat.
More datasets will be collated from other organisations and their accessibility to a range of users will be noted (e.g., students, academics, researchers, external). These datasets will, depending on permissions, be available to use within the project.
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.
The purpose of this page/category is to gather input from the various stakeholders who will use the outputs from the project, or who have an interest in what the project delivers. Specifically, we want to gather user requirements to drive the direction of the project and any subsequent activity that follows on, eg, IGIBS Mark II, other JISC programmes/projects, NERC activity, etc. If you have an interest in seeing the emerging UK National Spatial Data Infrastructure (SDI) and our Academic SDI better integrated, please tarry; comment and let us know what you think.
