Zusammenfassung:The invention relates to a computer-implemented method of monitoring a liquid resource stored in a lake, comprising the steps of determining a level of the liquid resource in the lake based on a satellite image of the lake and of determining a volume of the liquid resource in the lake based on the determined level and on a volume function of the lake which associates a volume to a given level. Determining said level comprises identifying within the satellite image a contour representative of a shoreline of the liquid resource within the lake and determining a height of the contour based on an elevation model of the lake aligned with the satellite image.
