Data visualisation is an essential tool for effective communication and interpretation of information. Visualisation of information using images is easier compared to numerical values. Google Earth provides a platform for a practical monitoring site visualisation system. A real-time web-based water quality monitoring system was deployed on Google Earth based on National Water Quality Index of Malaysia (NWQI). The system used graphical representation through vary shape and colour for easy interpretation of water quality status. NWQI index uses; pH, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand, total suspended solids and ammonical nitrogen. The use of different colour, shades of a hue and shapes for the system can motivate public to participate in environmental conservation. The colour used to represent WQI value on the map is derived from a single hue scheme of different quantities which produce varying brightness and shades. Web-based WQI index can be used to identify pollution sources based on the graphical representation of water quality trend. The system is assessed by evaluating spatial variations water quality of a river in Peninsular Malaysia known as Langat River for 2005, 2010 and 2015. The water quality index status through visualisation can be accessed at the following URL – http://www.umlivinglabsystem.com/SiteViewer/SiteViewerAvgSL.

基于Web的水质指数可视化系统

数据可视化是有效交流和解释信息的重要工具。与数字值相比,使用图像显示信息更容易。Google地球为实用的监视站点可视化系统提供了一个平台。基于马来西亚国家水质指数(NWQI)的实时网络水质监测系统已部署在Google Earth上。该系统通过变化的形状和颜色使用图形表示,以便于解释水质状况。NWQI指数用途;pH值,溶解氧,化学需氧量,生化需氧量,总悬浮固体和氨氮。系统使用不同的颜色,色调和形状可以激发公众参与环境保护。用于表示地图上WQI值的颜色是从具有不同数量的单个色调方案中得出的,该方案会产生变化的亮度和阴影。基于Web的WQI指数可以基于水质趋势的图形表示来识别污染源。通过评估马来西亚半岛2005年,2010年和2015年的兰加特河的河流水质的空间变化来评估该系统。可通过以下URL访问通过可视化显示的水质指数状态– http://www.umlivinglabsystem。 com / SiteViewer / SiteViewerAvgSL。
