This paper presents a global sharing analysis and visualization of water quality analysis by 5D World Map (5DWM) system. The data resources in this research collected from Sichang Island, Chonburi province, Thailand during 1990 to 2002 and 2010 to 2017. Six parameters of water quality were selected during 1990 to 2002 i.e. chlorophyll a, ammonia, nitrite, nitrate, phosphate and. The total locations sites were 21 stations which situated around Sichang Island. Otherwise, ten parameters were selected during 2010 to 2016 i.e. temperature, salinity, dissolved oxygen (DO), pH, ammonia, nitrite, nitrate, phosphate, silicate, and alkalinity. On the other hand, eight parameters were selected in February and July 2017 i.e. temperature, pH, oxidation reduction potential (ORP), conductivity, turbidity, dissolved oxygen (DO), TDS (Total Dissolved Solids), and salinity. All parameter of water quality was added and display by 5DWorld Map in order to visualize and sharing the water quality. Our results showed that 5DWorld Map can apply to environmental analysis and semantic computing. We apply the dynamic evaluation and mapping functions of multiple views of temporal-spatial metrics, and integrate the results of semantic evaluation to analyze environmental multimedia information resources. 5D World Map System for world-wide viewing for Global Environmental Analysis for water quality around Sichang Island, Thailand was reported in this study.
