## Methodology

Planning Datahub application descriptions containing ‘data centre’, ‘data center’ or ‘datacentre’, grouped by published decision and mapped at the supplied application centroid. This is a discovery view, not a register of operating sites: one project may have several applications, minor works are included, wording can miss relevant schemes and borough filing coverage is uneven.
