Mk (Malanjkhand): Malanjkhand is known for its copper deposits and is one of the largest copper mines in India. 6. MR (Mahanadi Rift): The Mahanadi Rift is a geological feature related to the rifting of the Indian Pl...

Solar Radiation and Remote Sensing

Satellite Remote Sensing Satellite remote sensing is the science of acquiring information about Earth's surface and atmosphere without physical contact , using sensors mounted on satellites. These sensors detect and record electromagnetic radiation (EMR) that is either emitted or reflected from the Earth's surface. Solar Radiation & Earth's Energy Balance Solar Radiation is the primary source of energy for Earth's climate system. It originates from the Sun and travels through space as electromagnetic waves . Incoming Shortwave Solar Radiation (insolation) consists mostly of ultraviolet, visible, and near-infrared wavelengths . When it reaches Earth, it can be: Absorbed by the atmosphere, clouds, or surface Reflected back to space Scattered by atmospheric particles Outgoing Longwave Radiation is the infrared energy emitted by Earth back into space after absorbing solar energy. This process helps maintain Earth's thermal bala...

Morpho-Tectonic Framework of India

The MorphoTectonic Framework of India refers to the combined study of the country's landforms (morphology) and its geological tectonic features. This framework provides insights into how geological forces have shaped India's topography over millions of years. Here's a breakdown of this concept: 1. Morphology: This aspect focuses on the physical features and landforms of India. It includes the study of mountains, plateaus, plains, valleys, rivers, and other surface features. For example, the Himalayas, Western Ghats, IndoGangetic Plains, and Deccan Plateau are prominent morphological features of India. 2. Tectonics: Tectonics deals with the movement and deformation of the Earth's lithosphere (the outermost rigid layer of the Earth). In the case of India, it primarily involves the interactions of the Indian Plate with neighboring tectonic plates. India is situated at the convergence of several major tectonic boundaries:     Collision with the Eurasian Plate: The most sign...

Neighbourhood Operations

 Neighbourhood Operations in GIS? In GIS and raster data , neighbourhood operations look at a group of nearby pixels (not just one) to understand or change a pixel's value. Think of it like checking what's around a house before deciding what color to paint it! Why "Neighbourhood"? Each pixel has " neighbours " (just like how your house has nearby houses). Neighbourhood operations check these nearby pixels and do some calculation to get a new value. 1. Aggregations (Summarizing Nearby Values) Aggregation means combining values of several pixels into one. We do this to: Find the average of surrounding pixels Find the minimum or maximum value Smooth the map (make it less rough) 🧒🏻 Example: Imagine checking the test scores of 9 students sitting around you and finding the average score . That's aggregation!  2. Filtering Techniques Filtering is used to improve or highlight features in a raster image, just like f...

India – Geographic Location – Spatial Significance

India's geographic location holds immense spatial significance due to its position on the world map. Here's an explanation of India's geographic location and its spatial significance: Geographic Location: India is a vast South Asian country located on the Indian subcontinent. Its geographic coordinates are approximately between 8°4'N and 37°6'N latitude and 68°7'E and 97°25'E longitude. It is surrounded by several important bodies of water: - To the west, it has a coastline along the Arabian Sea. - To the east, it is bordered by the Bay of Bengal. - To the south, it faces the Indian Ocean. - To the north, India shares its land borders with Pakistan, China, Nepal, Bhutan, Bangladesh, and Myanmar. Spatial Significance: 1. Strategic Location: India's location places it at the crossroads of South Asia and the Indian Ocean region. This strategic position has made it historically important for trade, diplomacy, and geopolitics. 2. Trade and Commerce: India...
