摘要

GIS protocols were developed to map ecological landtypes (ELTs) containing dry slopes, mesic slopes, dry ridges, mesic ridges, and bottomlands for the Hoosier National Forest, Indiana, United States. The mapping techniques included separating hills from valleys, dividing hills into north- and south-facing slopes, differentiating narrow from wide ridges, and noise removal with raster and vector methods. This article examined ELT mapping with both 30- and 10-m resolution data. This article also compared different GIS operations involved in ELT mapping. The accuracy of the ELT map created was assessed on the ground, and accuracy could reach 100% if boundary-location and small-area errors were excluded. The GIS protocols involved in this study were effective and have broad implications for mapping ELTs in other geographic areas. For larger areas, more automated GIS procedures will be necessary.
