   <gmd:statement>            <gco:CharacterString>Il dataset descrive l'accrescimento dei nuclei insediativi a partire da quanto rilevabile dalle foto aeree del 1954.I nuclei sono stati individuati e perimetrati digitalmente distinguendoli per epoche successive, e distinguendoli in quattro fasi.L'analisi si è basata su foto aeree (volo della RAF - 1954), su Carta Tecnica Regionale rasterizzata (1970), su Carta Tecnica Regionale digitalizzata (1993) ed il suo successivo aggiornamento (2002).La digitalizzazione dei poligoni così individuati è stata realizzata con i consueti strumenti di disegno digitale, utilizzando la CTR come dominio cartografico.La toponomastica dei nuclei deriva dalla stessa CTR, mentre la classificazione del tipo di principio insediativo di appartenenza e gli elementi attrattori o generatori individuati, risultano essere stati assegnati coerentemente ai principi ispiratori e di indagine dettati dal Quadro Conoscitivo del Piano Strutturale.Il Quadro Conoscitivo è stato realizzato nell'ambito dello SMAS (Schema Metropolitano dell'Area Senese), ovvero comprendendo il territorio del Comune di Siena e dei cinque comuni contermini: questo motiva la presenza di aree oggetto di analisi poste anche al di fuori dei confini amministrativi del Comune di Siena.Il dataset costituisce la base della tavola di Quadro Conoscitivo del Piano Strutturale B.8.1.01 e redatto in seguito alla LR Toscana 1/2005Il Quadro Conoscitivo del Piano Strutturale è interamente consultabile al seguente
