1. A method of determining one or more conditions of a geographical line, GL, or its surroundings, the GL being a man-made or natural continuous, predominantly one-dimensional geometric structure on the surface of the earth,
the method comprising:
acquiring geo-referenced earth observation data representing one or more spatially overlapping imagery layers covering from an aerial or space perspective a specific region of interest, ROI, of the Earth's surface, the ROI comprising the GL;
geometrically transforming the geo-referenced observation data, at least in parts, by means of a non-linear, geometric transformation into a local internal frame of reference of the GL within the ROI to obtain a mapping of the geo-referenced observation data to respective corresponding coordinates within the local internal frame of reference of the GL, in which the GL rests and is represented therein as a line of a predetermined selected geometry; and
Evaluating the mapped earth observation data as represented in the local internal frame of reference of the GL according to a classification scheme being a scheme for classifying one or more conditions of a geographical line according to a set of classes to obtain evaluation data representing a classification of one or more properties of the GL or of its surroundings according to one or more conditions of the GL, each such condition being a detected or detectable state of the GL at one or more locations on the GL.
