L\u2019arch\u00e9ologue australien Damian Evans vient d’annoncer la d\u00e9couverte de cit\u00e9s anciennes bien plus vastes que l’on croyait, dissimul\u00e9es par la jungle, autour des temples d\u2019Angkor au Cambodge.

Cette m\u00e9thode de t\u00e9l\u00e9d\u00e9tection de plus en plus r\u00e9pandue, permet d’enregistrer les reliefs du sol au centim\u00e8tre pr\u00e8s, en occultant la couverture v\u00e9g\u00e9tale. Un scanner embarqu\u00e9 dans un avion ou un drone envoie des impulsions laser vers le sol et enregistre chaque \u00e9cho. La surface terrestre est ainsi d\u00e9crite m\u00eame \u00e0 travers les branches et la v\u00e9g\u00e9tation.
