Abstract

The present invention relates to an apparatus for determining agricultural relevant information in an agricultural environment. It is described to provide (210) a processing unit with at least one image of an agricultural area. The at least one image was acquired by at least one satellite and/or at least one aerial vehicle such that the at least one image was acquired through a substantial depth of the Earth's atmosphere. The at least one image corresponds with at least one area of the agricultural area such that each image of the at least one image corresponds to a different area of the agricultural area. The at least one image comprises remotely acquired reflectance intensity data relating to a plurality of features on the ground. An image of the at least one image is of a first area of the agricultural environment. The processing unit is provided (220) with at least one sensor data relating to the first area of the agricultural environment. The at least one sensor data was acquired by at least one ground based and/or at least one near ground based sensor. The processing unit implements (230) a radiation propagation model of the atmosphere that utilizes at least one model parameter. The at least one model parameter comprises at least one atmospheric scattering coefficient. The processing unit determines (240) modified at least one model parameter. The determination comprising utilization of the radiation propagation model, the remotely acquired reflectance intensity data of the image of the first area and the at least one sensor data relating to the first area. The processing unit determines (250) at least one agricultural relevant information for an examination area of the at least one area. The determination utilizes the radiation propagation model, the modified at least one model parameter and an image of the at least one image that is of the examination area of the at least one area.
