Remote sensors collect data by detecting the energy that is reflected from Earth. These sensors can be on satellites or mounted on aircraft (or on ships in the case of Sonar).
Lidar bounces a laser pulse (NOT radio wave) off a target and then measures the time (and distance) each pulse traveled. Those measurements reveal the relative heights of features on the ground struck by the laser pulses. These pulses can penetrate forest cover to record the shape of the ground below. That makes this technology especially valuable for mapping.
A LIDAR instrument principally consists of a laser, a scanner, and a specialized GPS receiver. Airplanes and helicopters are the most commonly used platforms for acquiring LIDAR data over broad areas. Two types of LIDAR are topographic and bathymetric. Topographic LIDAR typically uses a near-infrared laser to map the land, while bathymetric lidar uses water-penetrating green light to also measure seafloor and riverbed elevations.

- The mineral monazite is a major resource for rare earth elements.
- Beach sand deposits are an important source for supplies of rare earth elements.

Neither 1 nor 2
Atomic Minerals Directorate for Exploration and Research (AMD), a constituent unit of Department of Atomic Energy (DAE), has the mandate to identify, evaluate and augment mineral resources of uranium, thorium, niobium, tantalum, beryllium, lithium, zirconium, titanium, rare earths (containing uranium and thorium) and other beach sand minerals like garnet and sillimanite.
The resources of the minerals comprising BSM (Beach Sand Minerals) are given below:
- Thorium (as monazite) - 12.47 million tonne (1.12 million tonne ThO2)
- The mineral monazite, containing ~ 55 - 60% total Rare Earth Elements (REE), is also the major resource for REE.
- Titanium (as ilmenite, leucoxene and rutile) - 682.30 million tonne
- Zirconium (as zircon) - 35.75 million tonne
- Garnet - 187.46 million tonne
- Sillimanite -255.09 million tonne
One of the misconceptions about beach sand-mining is the assumption that it involves quarrying. This is patently false: Companies that operate in this field in southern Tamil Nadu, for instance, dredge only the top inch of beach sand. Any deeper, and they would be mining for silica, which is neither a rare earth mineral, nor of any use to the industry. The skimming is done every morning; each day, the sea deposits fresh layers of rare earth minerals on the beaches and by evening, much of it is washed away if not harvested. "
