Abstract: A method for determining a status of one or more tanks in a particular location or an amount of a commodity stored in a particular location comprises the steps of: storing information associated with each of the one or more tanks in a database; periodically conducting an inspection of each of the one or more tanks, including using a sensor to acquire a three-dimensional data set; analyzing the three-dimensional data set to determine a status of each of the one or more tanks and/or to calculate an amount of the commodity that is stored in one or more tanks; and communicating information about the status of each of the one or more tanks and/or the amount of the commodity that is stored in one or more tanks at the particular location to a market participant.
