Methodology
Group Measure
Measures contain both chemicals and water property, so according to unit and basic knowledge, divide them into 3 main groups: water temperature, macrozoobenthos and chemical sets including other chemicals of possible interest.
The heat map implies that Boonsri, Chai, Kannika and Sakda have most observed chemicals. Meanwhile, their water temperature and Macrozoobethos records take up more proportion than other locations. This is reference for further analysis.
Assume number of measure records can represent the waterways situation to a certain extent: the more chemicals have been recorded, the more abnormal or serious condition the preserve site has. To clearly observe these 3 measure groups varying with each other, here we could use line charts for general average measure values’ changing pattern. Take this line chart as an example, at Boonsri, Macrozoobethos records had been taken from 1998 to 2012; the average value was increased sharply over the first year period and then slowly subsequently; from 2005 to 2007, records number where more than other years.
