How Well Do We Know Northern Land Cover? Comparison Of Four Global Vegetation And Wetland Products With A New Ground-Truth Database For West Siberia, Karen E. Frey, Laurence C. Smith
Geography
An unprecedented collection of 2161 geolocated, irregularly spaced field observations of land cover spanning ∼106 km2 throughout West Siberia suggests that currently available land cover classification products are remarkably poor indicators of vegetation type and water body extent in this northern Welland environment. The ground-truth data are compared with (1) the Global Land Cover Characteristics database derived from Advanced Very High Resolution Radiometer data (GLCC.AVHRR), (2) the Global Land Cover Classification derived from Moderate Resolution Imaging Spectroradiometer data (GLCC.MODIS), (3) the Global Lakes and Wetlands Database (GLWD), and (4) the West Siberian Lowland Peatland Database (WSLPD) using: (1) all land …
