It is critical to maintain an accurate 3D database of obstacles with online monitoring on a periodic basis to be able to design new procedures and improve upon earlier ones.
The advantages being:
- To be able to identify the ‘Controlling Obstacle’ accurately. Also to establish if the Controlling Obstacle has changed over the years.
- To be able to identify and check any clusters of High-rise obstacles which could become a large obstacle.
- To prepare a distance vs height profile of all the obstacles penetrating the OLS surfaces and to check if they violate the penetration criteria as laid out in the GSR 751 (E) Guidelines.
- To overlay the permissible FSI map over the 3D database to check violations if any.
