Inspector's report. Section 1 places the appeal site within the existing Google Ireland data-centre campus at the southern edge of Grange Castle Business Park South, which already contains two Google data centres (DC1 and DC2) and substations. The site wraps around the south, east and north of the existing facilities and is bounded by Profile Park to the east and Baldonnel Road to the south and west. Its central and western parts are hardcore brownfield. The report records the applicant's statement that the Google data centre has operated on these lands for more than ten years. evidence

Scope class: official_planning_register_application_point_as_campus_locator

Method: national_planning_register_point_epsg3857_to_wgs84_pyproj_3_7_1
Derivation: coordinate_transform
Precision scope: Point published by the merged national planning register for application SD24A/0164W (EPSG:3857 x -717873.43, y 7041124.32), converted to WGS84 with pyproj 3.7.1. It is used as a locator for Google's Grange Castle campus, which contains the 20.44 ha application site wrapped around the existing DC1 and DC2. It does not locate the new building, DC1, DC2, a footprint or a legal boundary.
Horizontal uncertainty: Not reported
The register publishes no positional accuracy or derivation for its application point; the 20.44 ha site extends several hundred metres around the existing buildings.
Geometry evidence: 396d0800

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
