 ## Funzioni gia implementate
 
-- Mappa interattiva Leaflet con sfondo satellitare Esri e sfondo stradale OpenStreetMap.
+- Mappa interattiva Leaflet con sfondi Esri, OpenStreetMap, OpenTopoMap, CARTO Voyager, Google Maps e Azure Maps configurabili tramite chiave.
 - Layer WMS ufficiale Agenzia delle Entrate: particelle, numeri particella, fogli, fabbricati, strade e acque.
 - Trasparenza configurabile del layer catastale.
 - Interrogazione WMS con click/tap sulla mappa.
 - Import di file KML, KMZ, GeoJSON e JSON.
+- Import GeoJSON compatibile con BOM, geometrie singole, array, FeatureCollection e coordinate Web Mercator EPSG:3857.
+- Filtro KML/KMZ `solo particelle` attivo per impostazione predefinita, con separazione dei MultiPolygon ed esclusione di GroundOverlay e perimetri del foglio; il layer foglio resta importabile tramite opzione.
 - Inquadramento e pulizia dei layer importati.
 - Disegno di marker, linee, poligoni e rettangoli.
-- POI/progetti salvabili in locale con `localStorage`.
+- Modalita rapide Area, Distanza e Cerchio disponibili direttamente sulla mappa, con superficie, perimetro, raggio, circonferenza e lunghezza dei singoli lati.
+- Misure permanenti attivabili anche sui layer importati da KML, KMZ e GeoJSON.
+- Toolbar di disegno completa di icone, modifica, eliminazione singola e pulizia di tutti i disegni/POI.
+- Archivio multiprogetto nella cartella privata dell'app, con nome, selezione da elenco, sovrascrittura ed eliminazione.
+- Ogni progetto salva file GIS, POI, disegni, traccia e inquadratura; l'inclusione delle particelle catastali rosse e' opzionale.
 - GPS nativo MAUI ad alta precisione con permessi Android/iOS.
 - Marker posizione, cerchio accuratezza in metri, tracciamento percorso.
 - Controllo se la posizione GPS cade dentro un poligono importato o disegnato.
 - Interrogazione WFS ufficiale Agenzia delle Entrate attorno alla posizione GPS per evidenziare la particella catastale corrente quando il servizio restituisce la geometria.
-- Ricerca Comune/Foglio/Particella tramite indice OnData e successivo recupero geometria dal WFS ufficiale AdE.
+- Mappa a tutto schermo con tab separati Catasto, Dati, Progetti e Impostazioni, adattabile agli schermi pieghevoli.
+- Ingrandimento oltre lo zoom satellitare nativo senza tessere "Map data not yet available".
+- Tendine concatenate Regione, Comune, Foglio e Particella.
+- Ricerca di localita e indirizzi eseguita nativamente con fallback Esri e OpenStreetMap, senza richieste CORS dalla WebView.
+- Catalogo dei Comuni incluso nell'APK e cataloghi regionali OnData scaricati in cache solo quando servono.
+- Ricerca catastale eseguita dal codice .NET nativo, senza DuckDB WebAssembly nella WebView Android.
+- La registrazione della traccia GPS e' disattivata all'avvio; la toolbar di disegno puo' essere mostrata o nascosta dal tab Progetti.
+- Pannello `Layer` accessibile direttamente dalla mappa, con checkbox sincronizzati per confini, numeri particella, fogli, fabbricati, strade e acque.
+- Le particelle cercate possono essere aggiunte una dopo l'altra, mantenendo contemporaneamente sulla mappa tutti i confini selezionati.
+- Comandi separati per rimuovere le particelle selezionate o pulire importazioni, disegni, POI e traccia GPS.
+- Anteprima WMS ufficiale mostrata dentro l'app senza aprire una nuova finestra Android.
+- Confini delle particelle selezionate e della particella GPS sovrapposti anche all'anteprima WMS corrente.
+- Richieste WMS catastali in EPSG:4258 compatibili con il servizio AdE; i numeri particella sono visibili alle scale di dettaglio consentite dal servizio (circa zoom 17 o superiore).
+- Collegamenti separati al Geoportale pubblico e all'Area riservata AdE per CAPTCHA, SPID/CIE e download ufficiali.

-Questo passaggio e' implementato nella schermata "Particella catastale". Per la massima affidabilita inserisci il codice catastale del Comune, ad esempio `F205` per Milano o `H501` per Roma.
+Questo passaggio e' implementato nel tab `Catasto`. Regione e Comune sono disponibili subito; alla prima selezione di un Comune l'app scarica il file della regione, da circa 6 a 72 MB, e lo conserva nella cache del dispositivo. Fogli e particelle vengono poi popolati automaticamente.

+I layer cartografici pubblici WMS/WFS sono open data e non richiedono CAPTCHA. Il CAPTCHA o l'autenticazione SPID/CIE appartengono ai servizi web di consultazione e download documentale: l'app li apre nel sito ufficiale dell'Agenzia e non tenta di aggirarli.

+## Azure Maps Gen2
+
+Nel tab `Impostazioni` sono disponibili gli sfondi `Strade - Azure Maps` e `Satellite - Azure Maps`. Per usarli:
+
+1. crea una risorsa Azure Maps con piano Gen2 nel portale Azure;
+2. copia una delle chiavi di sottoscrizione della risorsa;
+3. inseriscila in `Chiave sottoscrizione Azure Maps Gen2` e premi `Salva chiave Azure Maps`.
+
+La chiave viene validata prima del salvataggio e rimane nel `SecureStorage` del dispositivo; non e' inclusa nel codice o nell'APK. Lasciando vuoto il campo e premendo il pulsante, la chiave viene rimossa.
+
+La quota gratuita mensile Gen2 indicata da Microsoft comprende 5.000 transazioni per le mappe di base e 1.000 per le immagini satellitari. Una transazione raggruppa fino a 15 richieste di tessere. Oltre la quota si applicano le condizioni economiche della sottoscrizione Azure, quindi e' opportuno configurare budget e avvisi nel portale.
