ActivityLog is a general mobile phone application that helps urban climate researchers and social scientists study spatial-temporal dynamics of human interaction with urban environment. Specifically, ActivityLog-HeatMappers is designed to support the development of HeatMapper Citizen Science project, which attempts to understand the heat vulnerable population in Maricopa County, Arizona. Data collected through ActivityLog are timestamped, geo-referenced, and easily paired up with air temperature and relative humidity such as Kestrel Drop (Bluetooth enabled environmental data logger). ActivityLog-HeatMappers has five main functionalities. First, it notifies users at every two hours interval to remind about logging. Secondly, it periodically collects users’ locations at a certain pre-defined interval. Thirdly, it can be paired with Kestrel Drop device to inform users about current temperature, relative humidity and heat stress index. Fourthly, the mobile application contains a link to HeatMapper survey from Qualtric platform. Lastly, all collected data (Survey, Kestrel data) are synced with a cloud database that can help researchers to monitor data collection progress in a real-time manner. The research results help us understand user behaviors for daily log activities. We also evaluate data quality of activity logs based on various criterions locations, activities of users, etc. The research results can help us better understand how human activities interact with an urban thermal environment and inform planning policy development.
