Interpolation in space and time. (a) The variable data for track-point P _i is first interpolated in space (using one of several interpolation methods) based on the data from the available points in the environmental dataset native grid around P _i. (b) Similar spatial interpolations are conducted at the two nearest available points in time, the nearest before and nearest after the timestamp of the track-point P _i. Then, the two interpolated spatial values are interpolated in time to the timestamp of P _i.
