  Exploring the significance of geo-tagged information of a satellite image and
associated shadow information in the image to enable man-made infrastructure
dimensional characterization, in this paper a novel approach has been developed
to estimate the height of a man-made structure accurately. Our proposed method
applies shadow detection and shadow feature along with geo-tagged information
retrieved through Google Earth tools, to estimate the structural dimension of
the man-made infrastructure. To characterize the dimensional features of the
man-made structure, we have considered Google Earth satellite images with
precise and crisp edge as well as shadow length information, which have been
obtained using freely available Google Earth information retrieval tool.
Applying our proposed mathematical formulation, the height of man-made
structures as well as neighbouring structures have been estimated which can be
used for certain strategic decision purposes. The proposed method can be
applicable for professionals exploring dimensional characterization of
relatively low height constructions as well as defence purposes. Our proposed
model has outperformed majority of existing approaches, particularly in terms
of accuracy of height estimation of man-made structures.
