The register supports planning, development monitoring, and housing land supply assessment across the city, and access requires an API key.","native_lang":"en","access_level":"direct","formats":[],"capability_tier":"live","trust_score":59.75,"maturity":"executable","maturity_index":4,"maturity_counts_as_coverage":true,"mqa_score":63,"mqa_tier":"good"},{"id":"71607d05-70b4-40fb-9898-62192af8c348","type":"API","name":"Sheffield City Centre Boundary","slug":"sheffield-city-centre-boundary","description":"Pre Submission Proposals Map - City Centre Boundary","free_access_class":"FREE_KEY_REQUIRED","auth_type":"API_KEY","homepage_url":"https://utility.arcgis.com/usrsvcs/servers/d7e50f6175764e789530aa9a33024486/rest/services/AGOL/INSPIRE/MapServer/2/query?outFields=*&where=1%3D1","docs_url":"https://data.gov.uk/dataset/sheffield-city-centre-boundary","repo_url":null,"status":"ACTIVE","verification_state":"VERIFIED","tags":["boundaries"],"logo_url":"https://www.google.com/s2/favicons?sz=64&domain=utility.arcgis.com","primary_source_url":"https://utility.arcgis.com/usrsvcs/servers/d7e50f6175764e789530aa9a33024486/rest/services/AGOL/INSPIRE/MapServer/2/query?outFields=*&where=1%3D1","extraction_confidence":"0.40","created_at":"2026-06-07T22:09:13.033Z","updated_at":"2026-08-22T01:29:47.542Z","last_verified_at":"2026-08-22T01:29:47.542Z","deprecated_at":null,"ranking_score":51,"last_ranked_at":"2026-08-21T04:50:03.901Z","last_seen_at":null,"last_validated_at":null,"last_uptime_at":"2026-08-20T07:59:23.640Z","search_vector":"'a':107B 'allow':52B 'allowing':147B 'an':137B,181B 'analysi':81B 'analysis':176B 'and':150B,155B,167B,177B 'api':14B,109B 'applic':84B 'applications':179B 'arcgi':43B 'arcgis':138B 'area':94B,189B 'as':117B,160B 'attribut':61B 'attributes':156B 'authorit':87B 'authoritative':182B 'boundari':4A,11B,17B,58B,95C 'boundary':99A,106B,112B,153B 'centr':3A,10B,21B,93B 'centre':98A,105B,116B,188B 'citi':2A,9B,20B,92B 'city':97A,104B,115B,187B 'data':38B,133B 'defin':23B 'defined':118B 'definit':88B 'definition':183B 'endpoint':46B,141B 'for':170B 'framework':36B,131B 'geometri':59B 'geometry':154B 'geospati':13B 'geospatial':108B 'group':51B,146B 'in':119B,172B 'infrastructur':71B 'infrastructure':166B 'inspir':49B 'inspire':144B 'intend':74B 'intended':169B 'is':134B,158B,168B 'it':157B 'local':34B,78B,129B,173B 'map':8B,30B,70B,83B,103B,125B 'mapping':165B,178B 'mapserv':45B 'mapserver':140B 'nation':69B 'national':164B 'of':113B,127B,152B,162B,184B 'part':31B,66B,126B,161B 'plan':35B,79B 'planning':130B,174B 'pre':5B,27B,100B,122B 'pre-submiss':26B 'pre-submission':121B 'propos':7B,29B 'proposals':102B,124B 'provid':15B 'providing':110B 'publish':64B 'published':159B 'queri':54B 'queries':149B 'requir':85B 'requiring':180B 'rest':44B,139B 'retriev':56B 'retrieval':151B 'serv':40B 'served':135B 'servic':50B 'service':145B 'sheffield':1A,19B,91B,96A,114B,186B 'spatial':53B,80B,148B,175B 'submiss':6B,28B 'submission':101B,123B 'the':111B,120B,128B,132B,143B,185B 'uk':68B,163B 'under':142B 'use':76B,171B 'via':41B,136B","popularity_score":"0.0000","maintenance_score":"0.7000","institution_id":null,"institution_type":null,"country_code":"GB","official_confidence":40,"proof_summary":"official domain (gov.uk) (catalog: data_gov_uk)","source_seed_url":null,"is_public_sector":true,"published_at":"2026-06-07T22:09:13.033Z","geographic_scope":"NATIONAL","name_en":null,"description_en":"A geospatial API providing the boundary of Sheffield city centre as defined in the Pre-Submission Proposals Map, part of the local planning framework.
