A dashboard prototype I created during my internship at SODAQ. This web dashboard visualises PM2.5 concentration data collected by mobile air quality monitors mounted on bikes. The data was collected by volunteer cyclists in Utrecht, The Netherlands. The input data was raw csv downloaded an online API containing lat/lon coordinates and PM2.5 concentrations. I reformatted this data to generate lines. A part of the UI, I created a table that presents some basic statistics on the data collected by each air quality monitoring unit. The dashboard was built with HTML, Javascript (jQuery) and ArcGIS Javascript API.
