8. Introduction to Remote Sensing & GIS Remote sensing is the process of collecting information about an object or area from a distance, typically using satellites, drones, or aircraft sensors. 8

9. Introduction to Remote Sensing & GIS lower-resolution (larger pixel size) data, often used for broad-scale environmental monitoring and global analysisrs. 1. MODIS (Moderate Resolution Imaging Spectroradiometer) Resolution : 250m, 500m, 1km Satellites : Terra and Aqua (NASA) Applications : Global vegetation, ocean color, and atmospheric studies. 2. Sentinel-3 Resolution : 300m to 1.2km Mission : Part of the Copernicus program (ESA) Applications : Marine, land, and atmospheric monitoring 9

10. Introduction to Remote Sensing & GIS medium-resolution data (spatial resolution between 10m to 100m), widely used for regional studies and detailed environmental monitoring: 1. Sentinel-2 (Copernicus Program) Resolution : 10m, 20m, 60m Agency : European Space Agency (ESA) Applications : Land cover mapping, agriculture, forestry, and disaster monitoring. 2. Landsat Series 5/8 Resolution : 15m (panchromatic), 30m (multispectral), 60m–100m (thermal) Agency : NASA/USGS Applications : Urban planning, water resources, and land use/land cover analysis. 10

11. Introduction to Remote Sensing & GIS high-resolution data ( spatial resolution less than 10m ), used for detailed mapping, urban studies, precision agriculture, and security applications: Here are satellites providing high-resolution data (spatial resolution less than 10m), used for detailed mapping, urban studies, precision agriculture, and security applications: 1. WorldView Series (Maxar) Resolution : WorldView-3 : 31cm (panchromatic), 1.24m (multispectral) WorldView-4 : 31cm (panchromatic), 1.24m (multispectral) Applications : Urban planning, defense, and environmental monitoring. 2. Cartosat Series (ISRO) Resolution : Cartosat-3 : 25cm Cartosat-2 : 65cm Applications : Urban planning, resource mapping, and defense. 11

23. 23 RESEARCH METHODOLOGY

24. What is Research??? 24 Research = Re + Search i.e. search again Environmental Physical, Biological Social, psychological New Products | New Facts | New Concept Or Advancement of Existing Knowledge or Theories Search / Analysis New Understanding Efficacious Progress in  the fields of Life Publish Problem Selection

25. 25 Research Approaches Inductive research = Theory-building research   Deductive research = Theory-testing research Induction THEORY OBSERVATIONS Deduction Generalize Observation Test Hypothesis Inductive Research: Scenario : A man observes his cat for a week. Observation: Day 1: The cat sleeps for 18 hours. Day 2: The cat sleeps for 18 hours. Day 3: The cat sleeps for 18 hours. Generalization : "All cats must be lazy creatures that sleep 18 hours a day." Deductive Research: Scenario : The same man reads online, "All cats are nocturnal hunters." Hypothesis : My cat hunts at night. Test : He sets up a camera to record his cat overnight. Results : The camera footage reveals... the cat snuggled into a blanket. Conclusion : "Maybe my cat missed the training about being a nocturnal hunter!" 25

26. Methods & Methodology 26 Methods = Techniques & Procedure for data collection Types: -Interviews - Focus groups - Surveys - Experiments - Case studies - Observational studies - On-line data collection Methodology = Analysis of the          collected data Types: -  Qualitative -  Quantitative -  Mixed Method

27. Quantitative Research Process 27 Flood Vulnerability Quantitative Assessment of Padma River Theory : Flood vulnerability is influenced by physical, social, and economic factors. Hypothesis : Areas with lower elevation and higher population density are more vulnerable to floods. Research Design : Cross-sectional study using GIS and household surveys. Measures of Concept : Elevation, population density, land use, infrastructure, and flood frequency. Select Research Sites : Flood-prone regions along the Padma River ex. Faridpur. Select Respondents : Households, local authorities, and infrastructure data points. Administer Data Collection : Use satellite imagery, GIS mapping, and structured surveys. Process Data : Input into GIS software; organize survey responses in statistical software. Analyze Data : Apply statistical methods to identify vulnerability patterns and correlations. Findings : Identify high-risk zones and key vulnerability factors ex. Susceptibility Map Write Up : Present findings and recommendations for flood risk management.

28. Qualitative Research Process Flood Vulnerability Qualitative Assessment of Padma River General Research Questions : How do communities along the Padma River perceive and cope with flood vulnerability? Selection of Relevant Sites and Subjects : Select flood-prone villages and key informants (local leaders, residents, and officials). Collection of Relevant Data : Conduct interviews, focus group discussions, and field observations. Interpretation of Data : Analyze narratives to identify common themes in flood impacts and coping strategies. Conceptual and Theoretical Work : Develop frameworks linking community vulnerabilities to socio-economic and environmental factors. Writing up Findings/Conclusions : Present insights on vulnerability perceptions and adaptive strategies with policy recommendations. 28
