- 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.
- Centratura automatica una tantum sulla posizione attuale all'apertura, senza mostrare il punto o il cerchio e senza avviare il tracking GPS continuo.
- Punto e cerchio di precisione del GPS live possono essere mostrati o nascosti dalle impostazioni senza fermare il rilevamento.
- 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.
