To pursue this goal, a PPGIS （public participation geographic information system） was developed, allowing the interaction, discussion and public participation of the stakeholders and actors involved. This PPGIS emerged as a crowdsourcing tool, with the purpose of assisting the georeferenced contributes from the local users of the Marine Park, regarding several relevant subjects, such as pollution, economic activities, opportunities and threats to the Marine Park, providing visual, analytical, and demonstrative qualities.展开更多

This paper represents an approach to build a web-based GIS to store, manage, analyze and visualize the data of saline intrusion phenomenon. The novelty focuses on automating the workflow for the generation and publication of time series saline intrusion maps on server side. The analysis results are provided on the web browser interface.

The northern region, one of the administrative regions of the Nairobi City Water and Sewerage Company was used as a case study. The research has customized and integrated an open source WebGIS system based on Quantum GIS for spatial data creation, MapServer as a web GIS server and PostgreSQL/PostGIS as a relational database. GeoMOOSE was used for the development of an interactive and friendly geographic user interface. The developed system enables users to view and interact with the spatial data. The research focused on improving the efficiency and effectiveness of the decision making process and data sharing.展开更多
