Title

Maps, Charts, and Graphs - Oh My! Mining Rich Datasets with Dynamic Data Visualization

Presenter

Abstract

The Globe at Night project has been collecting data from citizen scientists around the world since 2006. This has resulted in a rich dataset of more than 100,000 observations. The data is multi-faceted, covering the time domain, location, and both qualitative and quantitative observations of light pollution in the night sky from more than 100 countries.

Up until this year, we've only scratched the surface of what that data can tell us. We've plotted that data on a map, and looked at the data in a global context, plotting the percentage of the total number of limiting magnitude measurements, which has told us that on average, the people who participate in GLOBE at Night see brighter skies and fewer stars over time.

This year, combining some SQL queries with the power of a JavaScript library for drawing HTML5 charts and graphs, we've begun to mine the dataset. This presentation describes how we did it and what we are learning.
