Overview : Create a map that incorporates open science data to explore how an issue in your community is shaped by the surrounding physical geography.

Background And Importance

Problem Scope: In Dharavi, Mumbai, a significant environmental challenge is waste management and pollution. The densely populated area faces severe issues with inadequate waste disposal and sanitation, leading to health hazards and environmental degradation.

Improper waste management contributes to:

1. Air Quality Degradation: Burning waste releases harmful pollutants, affecting respiratory health in the community.
2. Water Pollution: Contaminated water bodies from untreated sewage and waste runoff pose risks to public health and local ecosystems.
3. Land Degradation: Accumulation of solid waste clogs drainage systems, exacerbating flooding during monsoon seasons.

​

Why It Matters: Addressing these challenges through community mapping using GIS can help identify waste hotspots, track pollution sources, and facilitate targeted interventions for improved waste management and environmental health. This approach empowers residents to participate in creating sustainable solutions for their community.

Data Processing Steps for Extracting Satellite Images Using Sentinel EO Browser

• Access the Sentinel EO Browser: Open web browser and navigate to the Sentinel EO Browser website.
• Search for Your Area of Interest: Use the map interface to zoom in on your area of interest Dharavi, Mumbai.
• Select Date Range: Set the desired date range for the satellite images you want to analyze. This helps in capturing the most relevant data for yo study.
• Apply Filters for Cloud Cover: Use the cloud cover filter to specify the maximum allowable percentage of cloud coverage in the images.
• Apply Spatial Queries: Use the spatial query tools to refine selection based on specific criteria, such as image resolution or specific satellite missions (e.g., Sentinel-2).
• Select and Preview Images: Browse the filtered results to find suitable images. Click on each image to preview it and ensure it meets your requirements.
• Define Bounding Boxes (if needed): If you need to extract a specific area from the selected images, draw a bounding box around the region of interest to focus your analysis.
• Download Selected Images: Once you’ve identified the appropriate images, click on the download option. Choose the desired format and resolution for your analysis.

Future Scope & Its Application

Potential Improvements:

Real-Time Data Integration: Incorporating real-time data feeds from environmental sensors could provide up-to-date information on air quality, noise pollution, and waste levels

Mobile Data Collection: Developing a mobile application for residents to report issues such as overflowing waste bins or waterlogging could improve community engagement and data accuracy.

Historical Data Analysis: Integrating historical data on waste management practices, pollution levels, and health impacts can help identify trends and evaluate the effectiveness of implemented solutions over time.

​

Real Time Application:

Informed Policymaking: Policymakers can leverage the insights generated from the mapping project to make data-driven decisions on resource allocation, infrastructure development, and community health initiatives.

Community Empowerment: By involving residents in the mapping process, the project fosters community engagement, empowering locals to advocate for their needs and participate actively in solutions.

Research and Development: Researchers can use the data and maps for studies on urban ecology, public health, and social dynamics in densely populated areas.

Summary

The Dharavi web map project stands as a critical initiative aimed at tackling the pressing environmental challenges faced by this densely populated community. By utilizing GIS technology and community mapping, the project provides a platform for visualizing waste management issues, air and water quality, and overall environmental health. This initiative not only empowers residents by involving them in data collection and decision-making but also equips policymakers and researchers with valuable insights to inform targeted interventions. The potential for improved public health, sustainable practices, and enhanced community engagement underscores the project's importance in addressing the hardships faced by the people of Dharavi.
