Development of a Web-based information system for Bangkok, Thailand. Report on the development of user requirements

Abstract

This report describes the user requirements of the Internet module to be developed as part of the 'Metropole Watch - Environmental Monitoring and Management System for the Chao Praya River in the Metropole of Bangkok'. There are 4 main types of data that shall be presented on the Internet/Web: 1. Map-data (river, khlongs, administrative units, location of sampling points, pollution sources, etc) handled by a geographical information system (GIS). 2. Classified/aggregated water quality data in comparison with water quality standards, to be displayed on the map. 3. Time plots (graphs) of historical water quality data, displayed with water quality standards where these are defined. 4. Metadata (descriptions) of sampling locations and pollution sources. All of these types of data are either stored in the ENSIS 2.05 database, or linked to the database. This document focus on presentation of manual monitoring retrieved from the ENSIS database, and does not describe the presentation of on-line monitoring data sampled by the instruments delivered by Oceanor. However, the report points out the interaction and possible integration with the Web-presentation of on-line data.
