The mean (standard error) exposure to each feature during 24 hours. Exposure values were assigned to a grid of points with 2.5 meter spacing that covered the entire study area. Each GPS point’s exposure value was calculated using a Gaussian kernel centered on the GPS point and summarizing the exposure values of nearby gridpoints. Exposure measures are best interpreted as a relative quantity.
