Abstract

In the article by Hall and others (1995), a topographic correction factor (C) was developed for estimating actual land area by taking into account the effect of sloping terrain. An error that was made during image processing resulted in values of C being exaggerated. For this note, values of C for the example landscape in Glacier National Park were recalculated, and the results with and without the error are compared. It is shown that the error caused the mean value of C reported for the example landscape to be exaggerated by a factor of 2.62 times.
