Provenance information | The OSI 1:5000 boundary line was chosen as the base-layer upon which all habitat mapping was based. The SPA boundary data to be used for all habitat mapping was version 3 (Positioning Accuracy Improved (PAI) SPA boundaries in ITM). Previous versions of the SPA boundary were mapped on six inch maps and there are a number of discrepancies in SPA boundaries fitting neatly onto field boundaries in OSI 1:5000. If there were fields traversing the SPA boundary whole field, as it exists in the OSI 1:5000 base layer, was mapped. For this reason, a 500m buffer round the SPA boundary was established prior to mapping to ensure that any overlap was afforded full coverage in the habitat map. All habitats mapped by discrete polygons/lines were assigned an attribute “LAND_PARCE” within the relevant shape-file. “Select by location”, was utilised to select if the discrete polygon/line feature was within the SPA boundary. Features contained within the SPA boundary have a value of “IN” for this attribute. Features traversing the SPA boundary, or outside of the boundary but considered of importance with regards to providing an ecological corridor (such as a hedgerow bounding a field that has been excluded from the SPA) have a value of “OUT” for this attribute.
