Abstract:

This study addresses a two-class problem in automatic terrain classification. the basic-level terrain feature selected for initial delineation is a mount - an aggregation of elevated features including hills, mountains, and ranges. All remaining areas are classified collectively as non-mount. A method was developed to partition digital elevation models DEMs into mount and non- mount areas automatically. Then, the developed method is compared to those results obtained by a manual classification of synthetic stereo images produced from the same digital elevation data. The results of this work suggest that it may be possible to replicate the manual identification of mounts in certain physiographic regions. However, the general utility of the mountnonmount classification approach appears to be limited by the nature of the regional terrain and by the quality of available digital data.
