ESAP

Statistical software package for estimating field scale spatial salinity patterns from electromagnetic induction signal data (for Windows XP). The ESAP software package currently contains five programs:

ESAP-RSSD Designed to generate optimal soil sampling designs from bulk soil electrical conductivity survey information ESAP-Calibrate Designed to estimate both stochastic (regression model) and deterministic (soil theory based) calibration equations; i.e., the equations which you will ultimately use to predict the spatial values of one or more soil variables from your EM survey data. ESAP-SaltMapper Used to produce high quality 1-D or 2-D graphical output of your EM survey data and/or predicted soil variables. This software can also be used to map out the locations of tile lines in saline fields, using EM survey data. ESAP-SigDPA Signal Data pre-processing software for managing raw Conductivity/GPS data file. ESAP-DPPC Calculator Used to convert insertion four-probe conductivity data into soil salinity estimates.

All five programs have been designed to work together in a seamless and efficient manner, and each program employs a simple, easy to learn graphical user interface.
