Help is needed please...
Topographical features, especially that of buildings, have been extracted from LIDAR data, with the
LIDAR data being the sole data source. The features were extracted using a developed system called
'TOFEXS', Topographical Feature EXtraction System.
A Possible Solution.
A solution is now needed which will evalute the extracted topographical features which are stored in
vector form against a recognised industry standard vector data containing corresponding topographical
features. Ideas include creating signatures using geometric descriptors for each of the corresponding
features. Geometric desriptors include:
Minimum Bounding Rectangle dimensions
Anchor Line length
Average Angular Change
Average Separation of Successive Vertices
Perimeter/area ratio, compactness, eccentricity, elongatedness, and central radial parameters
I would be thoroughly grateful for any ideas or help on this evalution part, including the use of
signatures/geometric descriptors, or any other (maybe easier solution) that might exist.
Again Many Many thanks
