Development of an open source Web GIS tool for Borehole Data Management and spatial Analysis: A case Study of Addis Ababa and surrounding Towns

Abstract

This  paper has been addressed the key challenges of the management of the groundwater data by introducing the web based geographical information system framework for borehole information management. Traditionally, borehole data management in Addis Ababa and surrounding towns faces challenges in the data integrity, accessibility and utility across multiple sector. The conventional method involves paper records, spreadsheets and isolated database. This approach results in systems that are not user friendly, outdated information and error prone data that are not easily shared with users.The lack of geospatial capabilities in traditional systems further limits effective spatial analysis and decision making. This study addresses the challenges of managing fragmented groundwater data by developing a web based distributed data development system suing open source technologies including GeoServer, MapStore, PostGIS and QGIS.  The system transform scattered well data into an accessible analytical resources through an integrated platform ensuring real time availability while maintaining data integrity through standard workflows. In the present study, verification using ground control points that have proven system spatial accuracy with average control error of less than 1.5 meters has been achieved. Geospatial well data can now be visualized and analyzed in depth with the implemented solution. Users can view well locations on interactive maps and perform necessary spatial analysis with the system. The implemented solutions provide comprehensive capabilities for visualized and analyzed geospatial well data. The systems allow users to visualize well locations on interactive maps, extract detailed information and perform necessary spatial analysis. The platform demonstrates how web-based GIS technologies can be effectively integrated to manage essential groundwater information. The study represent a significant change from stand alone GIS to open access web GIS service which offers greater opportunity for sustainable solutions in water resource management and planning. The developed system eliminates the redundancy and inconsistency common in traditional approaches making spatial information easily accessible across enterprises at low cost to the users. In the geological, environmental and construction industries the web based platform provides a foundation for evidence based collaboration and improved decision making.The role of the systems in the supporting sustainable water resource management through advanced spatial data and broad stakeholder engagement has  be a major focus of the future work.
