The County Clare Wetlands Survey Patrick Crushell & Peter Foss 2008 _______________________________________________________________ 4.2 Data fields in the CWS GIS database Six different GIS shapefiles (MapInfo Tab files) were created during the course of the CWS each containing a number of different attribute fields as described below. 4.2.1 CWS Site Locations This file was created from an exported Excel document from the main CWS site database (section 4.1 above). All of the CWS sites and much of the information relating to each site are included within this file. The information relating to the sites are stored in columns of an Excel spreadsheet known as attribute fields. The title of the various attribute fields (columns) differ somewhat from the corresponding titles used in the CWS site database as detailed in Table 4.1 below. Due to time constraints, data was not entered into a number of fields. Table 4.1. Data field labels from the CWS site database and corresponding labels from the CWS GIS site locations database.

The County Clare Wetlands Survey Patrick Crushell & Peter Foss 2008 _______________________________________________________________ 4.2.2 CWS Site Boundaries This file shows the boundaries of known wetland sites in County Clare, where such boundaries were available in digital format or could be drawn with confidence. The various attributes fields associated with this file are as follows: CWS NAME CWS CODE(s) AREA SOURCE DESIGNATIO X_COORD Y_COORD OTHER_NAME OTHER_CODE MERGED_BOU This contains the site name as recorded in the CWS site database. The site code according to that recorded in the CWS site database. In the case of larger sites there may be a number of site codes referring to numerous sub-sites. A calculation field which automatically calculates the area contained within the site boundary. The source of the boundary is given in this field, this relates to the source of the boundary feature. Nature conservation designations of the site are recorded within this attribute field (i.e. NHA, SAC, SPA etc.). Automatically generated field giving the central (X) coordinate of the shape. Automatically generated field giving the central (Y) coordinate of the shape. In some cases the site may be known by a different name depending on the source of the boundary. In some cases the site may be known by a different code depending on the source of the boundary. Boundary was compiled from a merge of more than one boundary feature. 4.2.3 CWS Polygon Habitats This file shows the distribution and extent of the various wetland habitats recorded during the CWS throughout the county. Much of the information has been imported from third part sources. It is not possible to definitively confirm many habitat types by aerial photography therefore much of the wetland recorded during the CWS falls within the ‘unknown wetland habitat’ category, unless third party sources provided level 3 Fossitt habitat assignment data. The following attributes are associated with this shapefile: FOSSITT Full name and code of habitat according to Fossitt (2000). There is an additional category ‘unknown wetland type’, where it is possible to identify a wetland but not possible to assign it to a Fossitt category. FOS_CODE_1 Alphanumeric code according to Fossitt (2000) to level 1. FOS_CODE_2 Alphanumeric code according to Fossitt (2000) to level 2. FOS_CODE_3 Alphanumeric code according to Fossitt (2000) to level 3. AREA A calculation field which automatically calculates the area covered by the habitat. SOURCE The source of the habitat shape is given in this field, this relates to the dataset from which the habitat information originates. The code used within this field identifies bibliographic and GIS records as presented in the main report and Appendix 1. NAME Where the habitat area had a name associated with it in the origin file this has been retained. This is the case with many lakes. SEG_CD Individual code assigned to lakes from EPA lake dataset. 90
