Heatmap of Distinct Measure Count by Location
Seems most of the locations took records every year since 1998. However, 3 positions include Achara, Decha, Tansanee only take records start from 2009. And during 2005-2009, all the locations recorded more measures than other years, especially in 2009. |
| 2 | Measure Record For a better understanding of the waterways situation, I made a line chart of measure overview by time which allow us to know when a measure was been recorded. | Line Chart of Measure Record
The measure record is kind messy, some measure are recorded continuously since 1998. But some measure only be recorded for one year and the average value of most of them is 0. Some measures only be tested in recent years which are AGOC-3A,Chlorodinine,Methylpsmoline from 2014 and Total dissolved phosphorus from 2015. The 4 measures need analyze carefully to understand the recent situation of the pollution. |
| 3 | Water Temperature Water temperature need analyse alone due to the different unit. | line chart by Quarter
Seasons may have a greater impact on water temperature, that's the reason why I show this graph in quarter. And as we can see, the highest water temperature appear in Q3 which are July, August and September (similar with the seasonality) except Sakda whose highest water temperature appears in Q2. |
| Sample date | Date sample was taken from the location, and the data was recorded for 1,965 days from 11/01/1998 to 31/12/2016. | |
| Measure | Chemicals or water properties measured in the record which includes 106 different types. |
