The document outlines the development of a WebGIS platform for flood mapping in the Dera Ghazi Khan division of Punjab, Pakistan, focusing on the importance of flood risk assessment and disaster management. It details data collection methods, software tools used, and implementation strategies to create an interactive interface for users, including public and disaster management authorities. The platform aims to enhance flood monitoring capabilities and improve disaster response through accurate flood hazard mapping.

- 1. WebGIS-Based Flood Mapping of DG Khan Division BAKHAT ALI Institute of Geoinformatics and Earth Observation, Pir Mehr Ali Shah Arid Agriculture University Rawalpindi , Punjab, Pakistan [email protected] Semester: Semester 5th Couse name: WebGIS Couse code : RSG-405 3(2-1) SUBMITTED TO: DR.IMRAN SUBMITTED BY: BAKHT ALI REG.NO:22-Arid-2818
- 2. INTRODUCTIO N o Overview of Dera Ghazi Khan Division: Geography, climate, and flood-prone areas. o Importance of flood mapping and disaster management. o Role of WebGIS in flood mapping and management.
- 3. OBJECTIVE: •Develop an interactive WebGIS platform to visualize, analyze, and manage flood data in DG Khan Division, allowing users to assess flood risk, monitor real-time flood situations, and aid in disaster response.
- 4. DATA COLLECTION Satellite imagery (e.g., Sentinel-1 for radar-based flood detection, Landsat for multispectral analysis). River discharge data. Rainfall data from meteorological stations.
- 5. SOFTWARE & TOOLS o GIS Software: QGIS: For data processing and flood map generation. ArcGIS: For spatial analysis and mapping. o WebGIS Platforms: Open Layers: For building interactive maps. Geo Server: For publishing spatial data as web services. • PostGIS/PostgreSQL: Database for managing spatial data
- 6. IMPLEMENTATIO N • Host spatial data on GeoServer. • Create a map interface with tools for zooming, panning, and toggling layers. WebGIS Platform Development: • Develop user roles (public, disaster management authorities). • Provide access to flood risk maps and evacuation plans. User Access:
- 7. RESULTS & DISCUSSION • Presentation of flood hazard maps and real-time monitoring capabilities. • Accuracy and reliability of the flood mapping results. • Benefits of using WebGIS for flood management in DG Khan. This Photo by Unknown Author is licensed under CC BY
