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.
