Intensive forest management requires spatial information of land properties at scales finer than those depicted in most conventional surveys, maps, and databases. Landform segmentation, a branch of Digital Terrain Analysis that groups similar topographic attributes into larger spatial units called landform element complexes (LECs), may provide an efficient, quantitative approach for modeling spatial variability at the scales relevant to land planners and managers. Landform segmentation was used in a deciduous forest stand on the Oak Ridges Moraine in southern Ontario, Canada in order to examine effects of topography on soil and stand properties used in indices of soil quality and stand productivity. Significant differences were recorded between the LEC spatial units in what is conventionally considered to be a homogenous forest stand on one soil unit. Fine-scale spatial maps of the results were constructed to demonstrate improvements over conventional sources of soil and land information such as coarse-resolution 2-D maps.
