Claim 10:
11. An asset tracking device for use onboard an asset, the asset tracking device comprising:
an interface layer to obtain raw data from a data source onboard the asset, the asset being a vehicle or associated with a vehicle; wherein the raw data contains a target set of data that contains time-variant N-dimensional data, N being three or greater;
a memory to store the raw data;
a controller configured to:
determine a number of dimensions in the target set of data, wherein the target set of data contains at least a first dimension for a sequence of time values, a second dimension for a first type of data collected with respect to the sequence of time values, and a third dimension for a second type of data collected with respect to the sequence of time values;
apply a dimensionally generalized Ramer-Douglas-Peucker algorithm to the target set of data;
reduce the target set of data to a simplified set of data by selecting points with the dimensionally generalized Ramer-Douglas-Peucker algorithm, wherein points are selected from the target set of data for inclusion in the simplified set of data based on distances of the points to iteratively defined reference lines defined through portions of the target set of data in N-dimensional space, N being three or greater; and

a communication interface configured to transmit the simplified set of data to a server.
