Abstract: 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.

Abstract: A method of detecting a plume of a given gas composition from a hyperspectral image comprises obtaining a short-wave infrared (SWIR) image depicting an area of interest on a given date from an overhead image acquisition device, determining, for a plurality of wavelengths for which a given gas exhibits an absorption maximum, whether at least one pixel of the SWIR image is indicative of absorption of infrared light within the given gas, applying an anomaly detection algorithm to the SWIR image to detect an anomaly therein that is attributable to a presence of the given gas within the area of interest, and identifying pixels as indicative of an emission of the given gas for those pixels of the SWIR image that are determined to be indicative of absorption of the given gas and determined to be indicative of the anomaly attributable to the presence of the given gas.

Abstract: A method for detecting and quantifying gas emissions from an infrared image comprises obtaining an infrared image from an overhead image acquisition device, the overhead image acquisition device comprising an infrared sensor, determining an amount of variation in infrared light intensity within the infrared image, and correlating the amount of variation in infrared light intensity within the infrared image to a gas concentration of a gas emission located in an area of interest depicted in the infrared image.
