Green rating Project 🍏

The concept of a Green Rating Project in environmental geography relates to assessing and evaluating the environmental performance of various entities, such as buildings, infrastructure projects, or industries. It involves assigning a green rating or score based on their sustainability practices and their impact on the environment.

The Green Rating Project aims to encourage and promote environmentally responsible practices and policies by providing a standardized framework for assessment. It typically considers factors such as energy efficiency, water conservation, waste management, use of renewable resources, and overall environmental impact.

The process of a Green Rating Project involves gathering data and information about the entity being assessed. This can include details about the design, construction, operation, and maintenance practices. The information is then evaluated against predefined criteria or benchmarks to determine its environmental performance.

The criteria for evaluation may vary depending on the specific project or industry being assessed. For example, a Green Rating Project for a building might consider factors like energy consumption, use of sustainable materials, indoor air quality, and waste management. On the other hand, a Green Rating Project for an industrial facility might focus on pollution control measures, resource efficiency, and adherence to environmental regulations.

The assessment of a Green Rating Project often results in a numerical score or rating that reflects the entity's environmental performance. This rating can be used to compare different entities, identify areas for improvement, and guide decision-making processes. It also serves as a tool for consumers, investors, and policymakers to make informed choices that prioritize sustainability and environmental responsibility.

Overall, the concept of a Green Rating Project plays a crucial role in promoting sustainable development and raising awareness about the environmental impact of human activities. By incentivizing environmentally friendly practices, it contributes to the goal of achieving a more sustainable and greener future.

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...

Change Detection

Change detection is the process of finding differences on the Earth's surface over time by comparing satellite images of the same area taken on different dates . After supervised classification , two classified maps (e.g., Year-1 and Year-2) are compared to identify land use / land cover changes . Goal To detect where , what , and how much change has occurred To monitor urban growth, deforestation, floods, agriculture, etc. Basic Concept Forest → Forest = No change Forest → Urban = Change detected Key Terminologies Multi-temporal images : Images of the same area at different times Post-classification comparison : Comparing two classified maps Change matrix : Table showing class-to-class change Change / No-change : Whether land cover remains same or different Main Methods Post-classification comparison – Most common and easy Image differencing – Subtract pixel values Image ratioing – Divide pixel values Deep learning methods – Advanced AI-based detection Examples Agricult...

Landsat band composition

Short-Wave Infrared (7, 6 4) The short-wave infrared band combination uses SWIR-2 (7), SWIR-1 (6), and red (4). This composite displays vegetation in shades of green. While darker shades of green indicate denser vegetation, sparse vegetation has lighter shades. Urban areas are blue and soils have various shades of brown. Agriculture (6, 5, 2) This band combination uses SWIR-1 (6), near-infrared (5), and blue (2). It's commonly used for crop monitoring because of the use of short-wave and near-infrared. Healthy vegetation appears dark green. But bare earth has a magenta hue. Geology (7, 6, 2) The geology band combination uses SWIR-2 (7), SWIR-1 (6), and blue (2). This band combination is particularly useful for identifying geological formations, lithology features, and faults. Bathymetric (4, 3, 1) The bathymetric band combination (4,3,1) uses the red (4), green (3), and coastal bands to peak into water. The coastal band is useful in coastal, bathymetric, and aerosol studies because...

Geographic phenomena fields objects boundaries.

In geography, geographic phenomena refer to features or processes that can be observed and studied on Earth's surface. These phenomena can be classified into three main categories: fields , objects , and boundaries . Each category has distinct characteristics, representations, and applications in Geographic Information Systems (GIS). 1. Fields A field represents continuous, spatially varying data where a value is present at every location within the study area. It describes conditions that exist across a geographic area. Characteristics : Continuity : Fields have no discrete boundaries; the data is continuous. Gradual Variability : The values of a field change gradually across space. Representation : Typically modeled using raster data in GIS, where a grid structure assigns a value (e.g., temperature or elevation) to each cell. Examples : Temperature Map : Shows temperature variation across a region. Rainfall Distribution : Displays rainfall levels over a large g...
