Technical Abstract: In this report we describe and document the ESAP software package; a system of integrated, user-friendly programs designed to model and predict field scale spatial soil salinity patterns from electromagnetic induction (EM) survey readings. The ESAP software package consists of four programs which can perform the following functions; (1) analyze and validate EM signal data, (2) identify the locations of a minimal subset of EM survey sites fo soil salinity sampling, (3) transform the acquired EM signal readings into predicted salinity data throughout the entire survey area using the sample soil salinity data in conjunction with spatially based statistical modeling techniques, and (4) generate report quality maps of the predicted spatial salinity pattern, by depth, for the survey area. The use and application of each program is discussed in detail. Multiple tutorial examples are included throughout this report in order to demonstrate both data input preparation and the interpretation of out file results.
