Stratagem Resistivity Plotter (SRP)

The Stratagem Resistivity Plotter is simple tool for making 2-D plots of Stratagem Resistivity data. It uses the Python Matplotlib scientific plotting library and thus is open source free software. It is available as a Windows (32 bit) installer and as python source code as well. Using the installer for Windows requires no programming. The python code will run on Mac OSX and Linux as well, but using the python source would require installing python, numpy, scipy, and matplotlib and is left as an exercise for the advanced user. The program allows the user to combine high and low frequency mode soundings into one plot.

Download the 32 bit installer. Download the 64 bit installer. The 32 bit version will work on both 32 and 64 bit Windows. The 64 bit version will work only on 64 bit Windows.
