Abstract:

This report, the first of the series, describes the relationship of six geographic factors and introduces formulae for predicting three of them. Based on a 200-case sample of United States topographic maps, a study was made of the inter-relationships of six terrain factors highest elevation, lowest elevation, relief, contour counts, slope direction changes, and hilltops. The rank method of correlation was usedfor this analysis. From the preliminary correlations, three factors relief, contour counts, and slope direction changes were found to bemost significantly related. Further work with these three factors resulted in a series of regression equations, both simple and multiple,to be used for predicting any of these three elements when pertinent data for it are lacking.
