            <gco:CharacterString>In attuazione dell’Art. 92 del D Lgs 152/2006, che recepisce le disposizioni della Direttiva  Nitrati (91/676/CEE ), il presente strato informativo rappresenta la trasposizione cartografica delle Zone Vulnerabili ai Nitrati (ZVN), identificate sulla base dei fogli catastali, indicati negli Allegati delle Delibere di Giunta regionale di seguito elencate, che approvano la perimetrazione di dettaglio delle ZVN:
   -  DGR n. 520 del 16 luglio 2007
   -  DGR n. 521 del 16 luglio 2007
   -  DGR n. 522 del 16 luglio 2007
   -  DGR n.18 del 18 gennaio 2021
I fogli catastali sono stati dissolti per identificare i confini delle singole zone.

La codifica dei campi della tabella degli attributi dello strato informativo è la seguente:
ZONA: denominazione della Zona Vulnerabile ai Nitrati.
I seguenti campi archiviano le informazioni relative alle delibere sopracitate e agli allegati alle delibere: 
Z_07_520_A
Z_07_520_B
Z_07_521
Z_07_522_A
Z_07_522_B
Z_21_018_A
Z_21_018_B
Z_21_018_C

Il nome del campo è così composto:
Z_AA_DEL_T, con:
AA = anno delibera da 1 a 17;
DEL = numero delibera;
T (eventuale) = tabella delibera.
I campi sono gestiti in modo boolea n (S=appartiene) per indicare l'appartenenza dell'area ad una o più ZVN.</gco:CharacterString>
