Evolution of Indian Platform

The Indian Platform, also known as the Indian Shield or the Peninsular Shield, is a stable geological region that forms the core of the Indian subcontinent. It has a complex geological history that spans billions of years. Here's an overview of the evolution of the Indian Platform:

1. Archean Eon (4 billion to 2.5 billion years ago):

The earliest geological history of the Indian Platform dates back to the Archean Eon, during which some of the oldest rocks on Earth were formed.

The Dharwar Craton, located in the southern part of the Indian Platform, is one of the prime examples of Archeanage geological formations in India.

2. Proterozoic Eon (2.5 billion to 541 million years ago):

During the Proterozoic Eon, the Indian Platform witnessed significant geological events.

Sedimentary basins formed, leading to the accumulation of thick sequences of sedimentary rocks.

The Vindhyan Supergroup, a prominent sedimentary rock formation, was deposited during this time.

3. Rodinia Supercontinent (1.3 billion to 750 million years ago):

India was part of the supercontinent Rodinia during this period.

It was situated near the southern margin of Rodinia.

4. Breakup of Rodinia and Formation of Gondwana (750 million to 540 million years ago):

Rodinia began to break apart during the Neoproterozoic.

India separated from the supercontinent and was positioned closer to Antarctica, forming part of the Gondwana supercontinent.

5. Cambrian to Devonian Periods (541 million to 358 million years ago):

During this time, India experienced marine sedimentation and the deposition of sedimentary rocks in shallow seas.

6. Carboniferous to Permian Periods (358 million to 252 million years ago):

India was located near the equator and experienced extensive coalforming swamps and glacial deposits.

7. Mesozoic Era (252 million to 66 million years ago):

India remained part of Gondwana during the early Mesozoic, but it began drifting northward.

This northward movement eventually led to its separation from Gondwana and initiated the formation of the Indian subcontinent.

8. Cenozoic Era (66 million years ago to present):

The most significant phase in the evolution of the Indian Platform occurred during the Cenozoic.

India continued to move northward and eventually collided with the Eurasian Plate around 50 million years ago.

This collision resulted in the uplift of the Himalayan mountain range and the Tibetan Plateau, significantly impacting the Indian Platform's geology and topography.

The collision with the Eurasian Plate is a defining event in the evolution of the Indian Platform, shaping its current geological features and creating some of the world's most prominent mountain ranges, including the Himalayas. This collision also continues to influence seismic activity in the region. Overall, the geological evolution of the Indian Platform reflects its role in the assembly of the Indian subcontinent and its dynamic geological history.

Platforms in Remote Sensing

In remote sensing, a platform is the physical structure or vehicle that carries a sensor (camera, scanner, radar, etc.) to observe and collect information about the Earth's surface. Platforms are classified mainly by their altitude and mobility : Ground-Based Platforms Definition : Sensors mounted on the Earth's surface or very close to it. Examples : Tripods, towers, ground vehicles, handheld instruments. Applications : Calibration and validation of satellite data Detailed local studies (e.g., soil properties, vegetation health, air quality) Strength : High spatial detail but limited coverage. Airborne Platforms Definition : Sensors carried by aircraft, balloons, or drones (UAVs). Altitude : A few hundred meters to ~20 km. Examples : Airplanes with multispectral scanners UAVs with high-resolution cameras or LiDAR High-altitude balloons (stratospheric platforms) Applications : Local-to-regional mapping ...

Types of Remote Sensing

Remote Sensing means collecting information about the Earth's surface without touching it , usually using satellites, aircraft, or drones . There are different types of remote sensing based on the energy source and the wavelength region used. 🛰️ 1. Active Remote Sensing 📘 Concept: In active remote sensing , the sensor sends out its own energy (like a signal or pulse) to the Earth's surface. The sensor then records the reflected or backscattered energy that comes back from the surface. ⚙️ Key Terminology: Transmitter: sends energy (like a radar pulse or laser beam). Receiver: detects the energy that bounces back. Backscatter: energy that is reflected back to the sensor. 📊 Examples of Active Sensors: RADAR (Radio Detection and Ranging): Uses microwave signals to detect surface roughness, soil moisture, or ocean waves. LiDAR (Light Detection and Ranging): Uses laser light (near-infrared) to measure elevation, vegetation...

Resolution of Sensors in Remote Sensing

Spatial Resolution 🗺️ Definition : The smallest size of an object on the ground that a sensor can detect. Measured as : The size of a pixel on the ground (in meters). Example : Landsat → 30 m (each pixel = 30 × 30 m on Earth). WorldView-3 → 0.31 m (very detailed, you can see cars). Fact : Higher spatial resolution = finer details, but smaller coverage. Spectral Resolution 🌈 Definition : The ability of a sensor to capture information in different parts (bands) of the electromagnetic spectrum . Measured as : The number and width of spectral bands. Types : Panchromatic (1 broad band, e.g., black & white image). Multispectral (several broad bands, e.g., Landsat with 7–13 bands). Hyperspectral (hundreds of very narrow bands, e.g., AVIRIS). Fact : Higher spectral resolution = better identification of materials (e.g., minerals, vegetation types). Radiometric Resolution 📊 Definition : The ability of a sensor to ...

Optical Sensors in Remote Sensing

1. What Are Optical Sensors? Optical sensors are remote sensing instruments that detect solar radiation reflected or emitted from the Earth's surface in specific portions of the electromagnetic spectrum (EMS) . They mainly work in: Visible region (0.4–0.7 µm) Near-Infrared – NIR (0.7–1.3 µm) Shortwave Infrared – SWIR (1.3–3.0 µm) Thermal Infrared – TIR (8–14 µm) — emitted energy, not reflected Optical sensors capture spectral signatures of surface features. Each object reflects/absorbs energy differently, creating a unique spectral response pattern . a) Electromagnetic Spectrum (EMS) The continuous range of wavelengths. Optical sensing uses solar reflective bands and sometimes thermal bands . b) Spectral Signature The unique pattern of reflectance or absorbance of an object across wavelengths. Example: Vegetation reflects strongly in NIR Water absorbs strongly in NIR and SWIR (appears dark) c) Radiance and Reflectance Radi...

geostationary and sun-synchronous

Orbital characteristics of Remote sensing satellite geostationary and sun-synchronous Orbits in Remote Sensing Orbit = the path a satellite follows around the Earth. The orbit determines what part of Earth the satellite can see , how often it revisits , and what applications it is good for . Remote sensing satellites mainly use two standard orbits : Geostationary Orbit (GEO) Sun-Synchronous Orbit (SSO) Geostationary Satellites (GEO) Characteristics Altitude : ~35,786 km above the equator. Period : 24 hours → same as Earth's rotation. Orbit type : Circular, directly above the equator . Appears "stationary" over one fixed point on Earth. Concepts & Terminologies Geosynchronous = orbit period matches Earth's rotation (24h). Geostationary = special type of geosynchronous orbit directly above equator → looks fixed. Continuous coverage : Can monitor the same area all the time. Applications Weather...
