Abstract: Systems, apparatus and methods for deriving a heatmap in a server are presented. A heatmap is formed from sensor measurements and/or wireless signal strength measurements that have been grouped. Sensor measurements are paired or group into complementary sets thereby reducing sensor bias and/or system bias that is otherwise included because of sensor drift and unbalanced directional travel. Similarly, wireless signal strength measurements are paired or group into complementary sets also reducing system bias.
