The remaining files (4-7) contain just one record for each address. Each file contains just two columnsUPRN - the Unique Property Reference Number of each address in DundeeSEED - the seedcode of the school catchment that the address is within Both columns are qualified with double quotes and separated with a comma. UPRNs are Unique Property Reference Numbers, as used in the Council's Corporate Address Gazetteer (CAG), the One Scotland Gazetteer (OSG) Or the Ordnance Survey AddressBase products.. For more information please see www.osg.scotSeedcodes are unique identifiers for Scottish Schools. A full list can be found at https://www.gov.scot/publications/school-contact-details/This collection is updated each night with the latest UPRNs from the Council's Corporate Address Gazetteer (CAG). SEED codes are taken from the Council's current catchment boundaries layer ("SchoolsAndCatchments - Current") which is updated as required. This typically happens around October or November before enrolment starts for the next school year each year. The data may therefore reflect the catchments that are due to take effect at the start of the next school year. For more details on the catchment data please see the the Council's current catchment boundaries layer ("SchoolsAndCatchments - Current") This data can be combined with Ordnance Survey OpenUPRN data to visualise it on a map in GIS software such as ArcGIS or QGIS. Or alternatively see the separate "UPRNs with school catchments" layer.
