Mapping Wetlands: A Comparison of Two Different Approaches for New Brunswick, Canada




This study compares areal interpretations of two provincial wetland maps in New Brunswick. The first consisted of discrete wetland units (vector data) derived from aerial photo interpretation. The second consisted of wet areas modeled by a newly developed depth-to-water index with continuous coverage across the landscape (raster data). The two maps were generally consistent with most discrete wetland areas embedded in the 010 cm depth-to-water class. The continuous model identified a larger wetland area, which mostly consisted of riparian zones and numerous small wetlands ( 1 ha) that were not captured by aerial photo interpretation.
