Socio-Economic Impact Assessment

A Socio-Economic Impact Assessment (SEIA) in disaster management delves into understanding the broad and often long-term effects of disasters on both the social and economic fabrics of affected communities. Unlike standard damage assessments that focus on physical destruction, SEIA evaluates how disasters disrupt livelihoods, alter social dynamics, and impact economic stability. The ultimate goal of SEIA is to inform effective and equitable disaster recovery strategies that consider the unique needs and vulnerabilities of affected populations.

Components of SEIA in Disaster Management

1. Social Impact Analysis

- Community Disruption: Disasters often displace communities, breaking up social networks and affecting group cohesion. Analyzing this disruption helps in planning effective resettlement and community rebuilding.    - Health Impacts: Immediate physical injuries, long-term health problems, and mental health challenges are common post-disaster. SEIA assesses these impacts to plan appropriate healthcare responses.    - Education Disruption: Disasters can lead to school closures, impacting children's education. This analysis informs the design of strategies to quickly restore educational services.    - Access to Essential Services: Disasters often interrupt access to water, sanitation, healthcare, and other essential services, affecting community well-being.

2. Economic Impact Analysis

- Direct Financial Losses: This includes property damage, loss of personal assets, and destruction of infrastructure. It's the most visible economic impact and influences immediate recovery needs.    - Loss of Livelihoods: Particularly in sectors like agriculture, tourism, and local industries. Disasters disrupt employment, affect income stability, and have a ripple effect on regional economies.    - Indirect Economic Losses: Beyond direct losses, disasters can reduce productivity, decrease tax revenues, and increase poverty levels, impacting long-term economic growth.    - Inflation and Market Instability: Prices for goods and services often rise in affected areas due to supply chain disruptions and increased demand for resources, adding economic strain on households.

3. Vulnerability and Resilience Factors

- Pre-existing Vulnerabilities: Socio-economic status, housing quality, and geographic location can influence how severely individuals and communities are impacted.    - Community Resilience: Social networks, local governance, and emergency preparedness all play roles in how quickly a community can recover.    - Cultural and Social Factors: Diverse community needs, such as those of ethnic minorities or marginalized groups, can influence recovery efforts, requiring tailored support.

4. Policy and Planning Implications

- Resource Allocation: SEIA findings help authorities allocate resources equitably based on assessed needs, ensuring vulnerable groups receive priority.    - Recovery Programs: Assessments provide data to develop programs that restore jobs, support businesses, and rebuild essential services.    - Risk Reduction and Preparedness: SEIA informs future planning to mitigate socio-economic vulnerabilities, such as by investing in infrastructure or establishing social safety nets.

ComponentFocus AreasKey Insights
Social Impact AnalysisCommunity disruption, health, education, servicesIdentifies impacts on social networks, mental/physical health, education, and essential service access
Economic Impact AnalysisFinancial losses, livelihoods, productivityAssesses direct/indirect financial losses, employment disruptions, and long-term economic costs
Vulnerability and Resilience FactorsPre-existing vulnerabilities, community resilienceExamines factors influencing disaster impact and recovery capability, including poverty levels and preparedness

Photogrammetry – Types of Photographs

In photogrammetry, aerial photographs are categorized based on camera orientation , coverage , and spectral sensitivity . Below is a breakdown of the major types: 1️⃣ Based on Camera Axis Orientation Type Description Key Feature Vertical Photo Taken with the camera axis pointing directly downward (within 3° of vertical). Used for maps and measurements Oblique Photo Taken with the camera axis tilted away from vertical. Covers more area but with distortions Low Oblique: Horizon not visible High Oblique: Horizon visible 2️⃣ Based on Number of Photos Taken Type Description Single Photo One image taken of an area Stereoscopic Pair Two overlapping photos for 3D viewing and depth analysis Strip or Mosaic Series of overlapping photos covering a long area, useful in mapping large regions 3️⃣ Based on Spectral Sensitivity Type Description Application Panchromatic Captures images in black and white General mapping Infrared (IR) Sensitive to infrared radiation Veget...

Photogrammetry – Geometry of a Vertical Photograph

Photogrammetry is the science of making measurements from photographs, especially for mapping and surveying. When the camera axis is perpendicular (vertical) to the ground, the photo is called a vertical photograph , and its geometry is central to accurate mapping.  Elements of Vertical Photo Geometry In a vertical aerial photograph , the geometry is governed by the central projection principle. Here's how it works: 1. Principal Point (P) The point on the photo where the optical axis of the camera intersects the photo plane. It's the geometric center of the photo. 2. Nadir Point (N) The point on the ground directly below the camera at the time of exposure. Ideally, in a perfect vertical photo, the nadir and principal point coincide. 3. Photo Center (C) Usually coincides with the principal point in a vertical photo. 4. Ground Coordinates (X, Y, Z) Real-world (map) coordinates of objects photographed. 5. Flying Height (H) He...

Raster Data Structure

Raster Data Raster data is like a digital photo made up of small squares called cells or pixels . Each cell shows something about that spot — like how high it is (elevation), how hot it is (temperature), or what kind of land it is (forest, water, etc.). Think of it like a graph paper where each box is colored to show what's there. Key Points What's in the cell? Each cell stores information — for example, "water" or "forest." Where is the cell? The cell's location comes from its place in the grid (like row 3, column 5). We don't need to store its exact coordinates. How Do We Decide a Cell's Value? Sometimes, one cell covers more than one thing (like part forest and part water). To choose one value , we can: Center Point: Use whatever feature is in the middle. Most Area: Use the feature that takes up the most space in the cell. Most Important: Use the most important feature (like a road or well), even if it...

Photogrammetry

Photogrammetry is the science of taking measurements from photographs —especially to create maps, models, or 3D images of objects, land, or buildings. Imagine you take two pictures of a mountain from slightly different angles. Photogrammetry uses those photos to figure out the shape, size, and position of the mountain—just like our eyes do when we see in 3D! Concepts and Terminologies 1. Photograph A picture captured by a camera , either from the ground (terrestrial) or from above (aerial or drone). 2. Stereo Pair Two overlapping photos taken from different angles. When seen together, they help create a 3D effect —just like how two human eyes work. 3. Overlap To get a 3D model, photos must overlap each other: Forward overlap : Between two photos in a flight line (usually 60–70%) Side overlap : Between adjacent flight lines (usually 30–40%) 4. Scale The ratio of the photo size to real-world size. Example: A 1:10,000 scale photo means 1 cm on the photo...

Logical Data Model in GIS

In GIS, a logical data model defines how data is structured and interrelated—independent of how it is physically stored or implemented. It serves as a blueprint for designing databases, focusing on the organization of entities, their attributes, and relationships, without tying them to a specific database technology. Key Features Abstraction : The logical model operates at an abstract level, emphasizing the conceptual structure of data rather than the technical details of storage or implementation. Entity-Attribute Relationships : It identifies key entities (objects or concepts) and their attributes (properties), as well as the logical relationships between them. Business Rules : Business logic is embedded in the model to enforce rules, constraints, and conditions that ensure data consistency and accuracy. Technology Independence : The logical model is platform-agnostic—it is not tied to any specific database system or storage format. Visual Representat...
