Breakpoint data is the name given to fine time resolution data collected by the SFWMD. Other organizations may refer to this data as "continuous" or "instantaneous" time series. The term breakpoint is derived from the data reduction used to minimize the number of redundant points stored in the database. This algorithm may be part of the data logger software or may be part of the post processing that occurs to data. Breakpoints are those points in a time series where the slope of the curve changes, or breaks, from a straight line. Points that are in between continuous breakpoints can easily be linearly interpolated and therefore provide little or no additional value.
