Variations in laser return occasions and wavelengths might be used to make digital Three-D representations of the springs.

In line with the official, the federal government has sought the associated fee and time estimate from the Survey of India for pan-India mapping following which a nationwide register for springs might be compiled and up to date at common intervals.
