This paper presents the results of a successful development of an algorithm to reduce processing time for mobile hosted location aware software applications. It starts with a review of location based services and discusses issues surrounding various designs to place the algorithm in context. The algorithm draws on various methodologies pioneered in the high-speed 3D graphics industry to reduce processing time checking for collisions between a user and location aware data points. The algorithm and experiment are presented in a concise manner before the results are shown. The results conclude that the algorithm presents a very significant improvement over brute force methods. With a database of 100,000 data points a 99% reduction in processing time is observed
