1. Data Source
The dataset is downloaded from: The Visual Analytics Science and Technology (VAST) Challenge
2. Data Overview
Boonsong Lekagul waterways Readings Data :
The dataset consists of readings of 106 chemicals measured from 1998 – 2016 which are collected from water sensors at 10 locations around the wildlife preserve.
Attributes in this dataset
1) Unique Reading ID
2) Value of the Chemical measure
3) Location where the chemical reading is collected
4) Sample date of chemical reading
5) Measure is the Chemical/Parameter is reading is measured from the water sensor of the waterways
Total number of chemical readings collected over years 1998-2016 are 1,36,825
Chemical Units of Measures Data: This dataset gives the units of all the 106 chemical measures for which readings where taken through water sensors.
Waterways Map in JPG format : The Map points the locations where the chemical measures are taken and also marks the dumping site
3. Data Preparation
1) Grouping of Chemicals –
To study the contamination of water based on recordings of 106 chemicals, I have grouped Chemicals together based on their common chemical properties, so as to make visualisations more clear to comprehend.
So, I formed 12 chemical groups as below -
