Texas Agricultural Experiment Station (TAES) filter. Its intended use is to remove as many erroneous yield data points as possible without relying on assumptions about the accuracy of the GPS locations, the number of machines operating in the field or the patterns of harvest. The program is written in Borland C++ 5.0 for the EasyWin format. EasyWin is a windows type DOS program.
