USING GPS, GIS, AND REMOTE SENSING AS A SOIL MAPPING TOOL

摘要

The basic objective of soil surveys is the same for all kinds of land, although the number of mapping units, their composition, and the detail of the mapping vary with the complexity of the soil patterns and the specific needs of the users. With the increased interest (needs) in site-specific management (precision agriculture) conventional soil survey maps may not be of an adequate scale to allow a producer to manage crop yield in a site-specific management scheme. Traditionally published soil survey mapping is done on a scale of 1:15840; however, site-specific management practices require a higher resolution (larger scale) of soil mapping in order to capture yield variability within a field.
