Il Ticino come non si era mai visto prima: Swisstopo ha messo online sul sito map.geo.admin.ch le vedute aeree più aggiornate, le foto ad alta risoluzione scattate nel 2018 che mostrano dettagli finora invisibili. La risoluzione al suolo è di 10 centimetri, non abbastanza comunque, assicura la responsabile della comunicazione Sandrine Klötzli, per rendere riconoscibile il volto di una persona sdraiata a terra.
L'ufficio di topografia fotografa il paese dall'alto dal 1920 e la tecnologia da allora ha fatto passi da gigante, consentendo di vedere dettagli sempre più precisi anche sullo schermo di computer e su un qualsiasi dispositivo mobile. Strumento indispensabile per la pianificazione territoriale, ma anche per lo studio dei ghiacciai e lo sviluppo della rete di sentieri, per non citarne che alcuni, foto e mappe di Swisstopo sono anche in 3D, accessibili a tutti in rete.
