the class of the polygon found | the row itself |
Scope: the row itself.
What was done to it: placed. The class of the polygon containing the life's grid reference, by point in polygon; cleared for a PO box (a large user whose LinkedSmallUserPostcode is NO LINKP). Shares the placement algorithm and its gate; there is no direct comparison with NRS codes for this version. (code: simd_ingest/core/rurality.py: classify, place, attach_rurality, is_po_box)
How it is checked (what each check tests; whether a build passed it is in that build's manifest.json["checks"])
rurality.2003-2004.columns_present: the shapefile carries the declared 6-fold and 8-fold columnsrurality.2003-2004.polygons: the shapefile has the declared number of polygonsrurality.2003-2004.reference_system: the shapefile is in British National Gridrurality.2003-2004.folds_nest: the 6-fold is exactly the official collapse of the 8-foldrurality.points_present: the records to place carry grid referencesreadback.history.rurality_values: every point is placed again from the saved file's grid references and equal
