Eco-mark Scheme 🐟

The Eco-mark Scheme is a concept in environmental geography that pertains to a certification program aimed at promoting environmentally friendly products and reducing the environmental impact of consumer goods. It is a labeling scheme that allows consumers to identify and choose products that meet specific ecological criteria.

The Eco-mark Scheme typically operates under the authority of a governmental or regulatory body responsible for environmental conservation and sustainability. It sets guidelines and standards for products to be eligible for the eco-label. These standards may cover various aspects such as resource conservation, energy efficiency, waste reduction, and the use of environmentally friendly materials.

The purpose of the Eco-mark Scheme is to encourage manufacturers to adopt sustainable practices in the production and distribution of their goods. By meeting the criteria set forth by the scheme, manufacturers can display the eco-label on their products, indicating that they meet the specified environmental standards. This label serves as a reliable indicator for consumers who are conscious of the environmental impact of their purchases.

The Eco-mark Scheme benefits both consumers and the environment. For consumers, it provides information and assurance that the products they are purchasing are environmentally friendly. It allows them to make informed choices that align with their environmental values and supports sustainable consumption patterns.

For the environment, the Eco-mark Scheme promotes the adoption of sustainable manufacturing processes, reduces the use of harmful substances, encourages resource efficiency, and promotes waste reduction. By recognizing and rewarding companies that adhere to these practices, the scheme encourages other manufacturers to follow suit, thus driving positive changes throughout the supply chain.

The specific criteria and guidelines of the Eco-mark Scheme may vary from country to country or even within different product categories. Some schemes focus on specific industries or sectors, while others encompass a broader range of consumer goods. The scheme may also include periodic reviews and audits to ensure ongoing compliance and improvement.

In summary, the Eco-mark Scheme is a labeling program designed to promote environmentally friendly products by setting criteria and standards for manufacturers to meet. It enables consumers to identify and choose products that have a reduced environmental impact, contributing to sustainable consumption and environmental conservation efforts.

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 ...

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...

Man-Made Disasters

A man-made disaster (also called a technological disaster or anthropogenic disaster ) is a catastrophic event caused directly or indirectly by human actions , rather than natural processes. These disasters arise due to negligence, error, industrial activity, conflict, or misuse of technology , and often result in loss of life, property damage, and environmental degradation . Terminology: Anthropogenic = originating from human activity. Technological hazard = hazard caused by failure or misuse of technology or industry. 🔹 Conceptual Understanding Man-made disasters are part of the Disaster Management Cycle , which includes: Prevention – avoiding unsafe practices. Mitigation – reducing disaster impact (e.g., safety regulations). Preparedness – training and planning. Response – emergency actions after the disaster. Recovery – long-term rebuilding and policy correction. These disasters are predictable and preventable through strong...

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 ...

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...
