A method comprising of GPS, DGPS, digital LASER range finder and compass use to get the coordinates of a location where a surveyor is unable to reach or open sky conditions not met. Laser range finder emits laser beams. Those beams bounce off distant objects and the range finder’s high speed clock measure the total time it took from when the beam left the unit until they returned. Since we know how to fast the beam was travelling (speed of light) the unit can simply use that time measurements to calculate the distance it travelled, and it displays the distance to the user. Digital compass provides azimuth angle (Ɵ) in radians. Integrating compass, laser range finder and GPS provides geographical coordinates.

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
