Concept of environment. Environmental Thought. Early environmental thinking. Environmentalism.

Geographical Explanation of Concepts:

1. Environment in Geography:

- Geographical Scope: In geography, the environment refers to the physical, biological, and cultural features of a specific area. This includes natural elements like landforms, climate, vegetation, and human-made features such as urban areas and infrastructure.

- Spatial Analysis: Geographers study how these environmental components interact, shaping the landscape and influencing human activities. Spatial patterns, distribution, and environmental changes are key considerations.

2. Environmental Thought in Geography:

- Geographical Perspective: Environmental thought in geography involves examining how human societies perceive and interact with their surroundings. Geographers explore the spatial dimensions of environmental attitudes and beliefs.

- Spatial Variation: Different regions may exhibit varying environmental thoughts influenced by factors like local ecosystems, historical experiences, and economic activities.

3. Early Environmental Thinking in Geography:

- Geographical Context: Early environmental thinking in geography emerged as a response to observable changes in landscapes due to human activities, especially during the Industrial Revolution.

- Spatial Impact: Geographers study how human actions altered geographical features and ecosystems, leading to insights into the spatial distribution of environmental degradation and conservation efforts.

4. Environmentalism in Geography:

- Geographical Dynamics: Environmentalism in geography is a spatially diverse movement advocating for sustainable practices, conservation, and protection of natural resources.

- Spatial Interventions: Geographers analyze how environmentalism manifests in different regions, influencing policies, land use planning, and community initiatives to address geographical challenges such as pollution, deforestation, and climate change.

In geography, these concepts are integral to understanding the dynamic relationships between humans and their environments, offering insights into spatial patterns, variations, and interventions for sustainable geographical development.

Radar Remote Sensing SAR

1. Radar and Radar Remote Sensing RADAR stands for Radio Detection and Ranging . It is an active remote sensing system that transmits microwave energy toward the Earth's surface and records the energy that is returned to the sensor as an echo or backscatter . Unlike passive optical remote sensing, radar does not depend on sunlight. Therefore, it can operate day and night and, at suitable wavelengths, can acquire data through clouds, haze and light rain. Hence, radar is widely described as an all-weather, day-and-night remote sensing technology . Basic principle Microwave pulse → transmission → interaction with surface → backscatter/echo → antenna receives signal → signal processing → radar image 2. Microwave Energy Radar systems use microwave electromagnetic radiation , generally in wavelength ranges from approximately 1 mm to 1 m . Important radar bands include: Band Approx. wavelength Common applications ...

Supervised Classification

Image Classification in Remote Sensing Image classification in remote sensing involves categorizing pixels in an image into thematic classes to produce a map. This process is essential for land use and land cover mapping, environmental studies, and resource management. The two primary methods for classification are Supervised and Unsupervised Classification . Here's a breakdown of these methods and the key stages of image classification. 1. Types of Classification Supervised Classification In supervised classification, the analyst manually defines classes of interest (known as information classes ), such as "water," "urban," or "vegetation," and identifies training areas —sections of the image that are representative of these classes. Using these training areas, the algorithm learns the spectral characteristics of each class and applies them to classify the entire image. When to Use Supervised Classification: - You have prior knowledge about the c...

Lidar

LiDAR (Light Detection and Ranging) is an active remote sensing technology that measures distances by illuminating a target with laser pulses and analyzing the time it takes for the reflected light to return. Unlike passive systems (e.g., cameras, multispectral sensors), LiDAR provides its own energy source (laser), allowing it to operate both day and night and even penetrate through vegetation canopies . 🔹 How LiDAR Works (Step-by-Step Process) Laser Pulse Emission The system emits rapid, short pulses of laser light (commonly in the near-infrared wavelength, 1064 nm ). Some systems emit up to hundreds of thousands of pulses per second . Interaction with Target Surface The laser beam strikes objects such as vegetation, buildings, or bare ground. Depending on the object's structure, part of the pulse may scatter or reflect. Return Signal Detection The sensor records multiple returns : First Return → typically vegetation canopy tops. ...

Isodata clustering

Iso Cluster Classification in Unsupervised Image Classification Iso Cluster Classification is a common unsupervised classification technique used in remote sensing. The "Iso Cluster" algorithm groups pixels with similar spectral characteristics into clusters, or spectral classes, based solely on the data's statistical properties. Unlike supervised classification, Iso Cluster classification doesn't require the analyst to predefine classes or training areas; instead, the algorithm analyzes the image data to find natural groupings of pixels. The analyst interprets these groups afterward to label them with meaningful information classes (e.g., water, forest, urban). How Iso Cluster Classification Works The Iso Cluster algorithm follows several steps to group pixels: Initial Data Analysis : The algorithm examines the entire dataset to understand the spectral distribution of the pixels across the spectral bands. Clustering Process : - The algorithm starts by divid...

Geometric Correction

When satellite or aerial images are captured, they often contain distortions (errors in shape, scale, or position) caused by many factors — like Earth's curvature, satellite motion, terrain height (relief), or the Earth's rotation . These distortions make the image not properly aligned with real-world coordinates (latitude and longitude). 👉 Geometric correction is the process of removing these distortions so that every pixel in the image correctly represents its location on the Earth's surface. After geometric correction, the image becomes geographically referenced and can be used with maps and GIS data. Types 1. Systematic Correction Systematic errors are predictable and can be modeled mathematically. They occur due to the geometry and movement of the satellite sensor or the Earth. Common systematic distortions: Scan skew – due to the motion of the sensor as it scans the Earth. Mirror velocity variation – scanning mirror moves at a va...
