SOIL AND TOPOGRAPHY SURVEYING

摘要

Methods of characterizing subsurface conditions in a selected geographic region (14) previously associated as a whole with a specific subsurface material characteristic reference profile such as from a USDA-NRCS soil survey. The method includes deploying a sensing tool (18,20) at selected positions (44) within the geographic region to determine a depth-referenced subsurface material characteristic such as soil type or strata, comparing the determined subsurface material characteristic to the subsurface material characteristic reference profile associated with the geographic region (14) to determine a correlation between the subsurface material characteristic reference profile and the depth-referenced subsurface material characteristic, and then deciding whether to deploy the tool at another position (44), and at what optimum position to deploy the tool, by considering the correlation.
