Surface water pollution and Environmental

Surface water pollution refers to the contamination of water bodies such as rivers, lakes, and oceans by various pollutants. These pollutants can come from both natural sources and human activities. Environmental impacts of surface water pollution are significant and include:

1. Ecosystem Damage: Pollutants like industrial chemicals, agricultural runoff, and sewage can harm aquatic ecosystems. They can disrupt the balance of aquatic life, leading to fish kills and the decline of biodiversity.

2. Water Quality: Contaminated surface water can affect the quality of drinking water sources. When pollutants enter rivers and lakes, they can make water unsafe for human consumption, leading to health risks.

3. Human Health: Surface water pollution can impact human health when polluted water is used for drinking, recreation, or irrigation. Contaminants like bacteria, heavy metals, and toxic chemicals can cause various diseases and health problems.

4. Economic Costs: Cleanup and mitigation of surface water pollution come with significant economic costs. Polluted water bodies can affect industries like fisheries and tourism, leading to financial losses in affected regions.

5. Habitat Destruction: Pollution can destroy the habitats of aquatic species. Chemical pollutants and sedimentation can smother riverbeds and disrupt the nesting grounds of various aquatic organisms.

6. Algal Blooms: Excessive nutrient pollution, often from agricultural runoff, can lead to harmful algal blooms. These blooms deplete oxygen, create dead zones, and release toxins that harm aquatic life and impact human activities.

7. Global Impact: Polluted surface water can eventually flow into the ocean, contributing to marine pollution and negatively affecting coastal ecosystems and wildlife.

8. Regulatory Challenges: Addressing surface water pollution often requires complex regulations and enforcement mechanisms. Governments and organizations must monitor and control pollution sources to mitigate environmental damage.

Efforts to combat surface water pollution include the enforcement of water quality standards, better waste management practices, and promoting sustainable land use and agriculture to reduce runoff. Protecting surface water quality is crucial for both ecological and human well-being and is an integral part of environmental conservation.

History of GIS

1. 1832 - Early Spatial Analysis in Epidemiology: - Charles Picquet creates a map in Paris detailing cholera deaths per 1,000 inhabitants. - Utilizes halftone color gradients for visual representation. 2. 1854 - John Snow's Cholera Outbreak Analysis: - Epidemiologist John Snow identifies cholera outbreak source in London using spatial analysis. - Maps casualties' residences and nearby water sources to pinpoint the outbreak's origin. 3. Early 20th Century - Photozincography and Layered Mapping: - Photozincography development allows maps to be split into layers for vegetation, water, etc. - Introduction of layers, later a key feature in GIS, for separate printing plates. 4. Mid-20th Century - Computer Facilitation of Cartography: - Waldo Tobler's 1959 publication details using computers for cartography. - Computer hardware development, driven by nuclear weapon research, leads to broader mapping applications by early 1960s. 5. 1960 - Canada Geograph...

Accuracy Assessment

Accuracy assessment is the process of checking how correct your classified satellite image is . 👉 After supervised classification, the satellite image is divided into classes like: Water Forest Agriculture Built-up land Barren land But classification is done using computer algorithms, so some areas may be wrongly classified . 👉 Accuracy assessment helps to answer this question: ✔ "How much of my classified map is correct compared to real ground conditions?" Goal The main goal is to: Measure reliability of classified maps Identify classification errors Improve classification results Provide scientific validity to research 👉 Without accuracy assessment, a classified map is not considered scientifically reliable . Reference Data (Ground Truth Data) Reference data is real-world information used to check classification accuracy. It can be collected from: ✔ Field survey using GPS ✔ High-resolution satellite images (Google Earth etc.) ✔ Existing maps or survey reports 🧭 Exampl...

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...

Development and scope of Environmental Geography and Recent concepts in environmental Geography

Environmental Geography studies the relationship between humans and nature in a spatial (place-based) way. It combines Physical Geography (natural processes) and Human Geography (human activities). A. Early Stage 🔹 Environmental Determinism Concept: Nature controls human life. Meaning: Climate, landforms, and soil decide how people live. Example: People in deserts (like Sahara Desert) live differently from people in fertile river valleys. 🔹 Possibilism Concept: Humans can modify nature. Meaning: Environment gives options, but humans make choices. Example: In dry areas like Rajasthan, people use irrigation to grow crops. 👉 In this stage, geography was mostly descriptive (explaining what exists). B. Evolution Stage (Mid-20th Century) Environmental problems increased due to: Industrialization Urbanization Deforestation Pollution Geographers started studying: Environmental degradation Resource management Human impact on ecosystems The field became analytical and problem-solving...

GIS: Real World and Representations - Modeling and Maps

Geographic Information Systems (GIS) serve as a bridge between the real world and digital representations of geographic phenomena. These representations allow users to store, analyze, and visualize spatial data for informed decision-making. Two key aspects of GIS in this context are modeling and maps , both of which are used to represent real-world geographic features and phenomena in a structured, analyzable format. Let's delve into these concepts, terminologies, and examples in detail. 1. Real World and Representations in GIS Concept: The real world comprises physical, tangible phenomena, such as landforms, rivers, cities, and infrastructure, as well as more abstract elements like weather patterns, population densities, and traffic flow. GIS allows us to represent these real-world phenomena digitally, enabling spatial analysis, decision-making, and visualization. The representation of the real world in GIS is achieved through various models and maps , which simplify...
