COPOSIS - An Agregation of Regional Soil Texture Data Sets Over North America

Description

COPOSIS is an aggregation of four soil texture dataset covering North America at a 0.1 degree resolution. COPOSIS stems from CONABIO, POLARIS, SIIGSOL and SoilGrids, the four components of the dataset. COPOSIS contains Sand and Clay content of soils (in %) for 6 soil depth intervals. The depth intervals are 0-5cm, 5-15cm, 15-30cm, 30-60cm, 60-100cm, 100-200cm. The border of each component of the COPOSIS is filtered to remove apparent geopolitical borders from the data set.
