Extending Spatial Hot Spot Detection Techniques To Temporal Dimensions, Sungsoon Hwang
Extending Spatial Hot Spot Detection Techniques To Temporal Dimensions, Sungsoon Hwang
Sungsoon Hwang
This paper presents how hot spot detection methods can be extended to allow for temporal dimensions. Major concerns are how temporal dimension is incorporated into the framework of point pattern analysis, while maintaining the capability of multi-scale analysis. The study elaborates on expanding the scope of (space) K function in order to count time in the analysis. With the explicit treatment of time as well as space, K function falls into three category depending on the way space and time are controlled; (1) space K function, (2) time K function, (3) space-time K function. Space K function is equivalent to …

The Atlas and Database of Air Medical Services (ADAMS) is a web-based, password-protected, geographic information system containing data on air medical service main and satellite base helipads, communication centers, rotorwing aircraft, and major receiving hospitals for trauma in the United States. ADAMS initially was developed to provide the geographic information needed to support realtime, wireless routing of automatic crash notification (ACN) alerts from a crashed motor vehicle to the nearest air medical transport service and trauma center. This coupling of ADAMS and ACN technology to enhance emergency communications is expected to speed delivery of emergency medical care to crash victims …
