Abstract: A system includes a biometric device, a biometric data collection device, and a spatial categorization system. The biometric device includes a biometric sensor to measure a biometric trait of a user. The biometric data collection device includes a positioning system and a biometric data storage system, and a third wireless transceiver. The positioning system is configured to provide spatial location values specifying a geographic location of the biometric data collection device. The biometric data storage system is configured to assign time stamp values to each of the spatial location values and biometric trait measurements. The spatial categorization system is configured to identify a biometric trait measurement indicating that a condition of the user has a value that exceeds a threshold, and to assign, based on the identified biometric trait measurement, a category identification value to a spatial region corresponding to the spatial location value.
