Haztrailz: Exploratory Analysis of Trajectory and Sensor Data
Abstract
The mini challenge 2 from VAST 2016 dealt with understanding the operations data from GAStech, a fictional company. We analyzed two weeks of this data including, (1) employee locations collected using proximity cards, and (2) sensor data containing temperatures, heating and cooling status, and chemical concentration levels. Our approach involved data cleaning and consolidation using R, the development of a custom trajectory visualization tool for the analysis of location data, as well as the use of existing analysis tools for the combined analysis of sensor and location data. In this paper, we discuss our analysis process, and report patterns and anomalies, as well as suspicious activities identified within the building.
