Digital Soil Mapping in the Absence of Field Training Data: A Case Study Using Terrain Attributes and Semiautomated Soil Signature Derivation to Distinguish Ecological Potential

<table>Location of the Jornada Basin LTER (JRN) in southern New Mexico at the northern extent of the Chihuahuan Desert (depicted in gray in Panel (a)). The 150 ha study site (white on inset map in Panel (b)) occurs on the Chihuahuan Desert Rangeland Research Center (CDRRC), which together with the Jornada Experimental Range (JER) constitutes the JRN.  Topographic complexity of the JRN is illustrated with a shaded relief map from a 10 m digital elevation model. Panel c is a natural color composite Landsat 7 ETM+ image of the study site (in white outline). Color bands display as Landsat 7 band 3 (red), band 2 (green), and band 1 (blue) with no histogram stretch applied.</table>
