The Snuffler seem to be a real nice piece of software. Thank You

I'm new in this forum and need an advice about ground modelling using homogeneous layers.
In my work I measure resistivity using the Wenner method in series of measures centered in one point and expanding the separation of electrodes (the "a" parameter) from 4, 8, 16, 32 meters, and replay the measure in an orthogonal direction for verification purposes.
The work consist in generate a 2 layer simplified model that match the real measures as better as possible. This is called 1D inversion.
Are there any software or Matlab script or Python script or anything that can help me in this work?
I don't know if this is the right place for doing this question. If no, tell me where and I will make it again.

Than you

Hi AleSeg,

These are links to some free, demo or paid 1D inversion programs.

I like Snuffler!

hello

can anybody here tell me what is the cheapest ground sensor i can use with this software
or is here any project that will work together with it?

a complete new field for me but interesting

regards

Hi,

I think the cheapest popular magnetic sensor is FGM-3, which is used in the EPE Magnetometer project or home-made sensor.

Snuffler support:
Geoscan RM15, TR Systems, EPE Resistivity Meters.
Geoscan FM18/FM36, Geoscan FM256, Bartington Grad601 Fluxgate Gradiometers.
also ARC-GEO Logger.

This software will work with any magnetic or resistive logger as EPE Magnetometer, which makes a suitable CSV or XYZ format files.
For example, Snuffler would show the thermal image from file made by the logger which has a thermal sensor.

Better Sensors ?

These FGM sensors have been around now for quite a while. What is the latest technology? Is there anything better that a hobbyist can afford? It would fun to build something that would map out black sand deposits on a beach.

Bartington offer new low power single axis sensors Mag678/Mag679 and three axis sensors Mag648/Mag649 also low cost sensors Mag670 and Mag690.

I have interest to this class of sensors.

DIY sensors and magnetometers

I guess, you should read http://www.geotech1.com/forums/showthread.php?t=1267 and US patents :

5744956 Low power magnetometer circuits having zero offset compensation Hawks 324/253

5239264 Zero-offset magnetometer having coil and core sensor controlling period of an oscillator circuit

You could, then do manual entry into the software, or if you build a microcontroller interface, then auto upload should be possible.

How to know depth using Snuffler

[rael]

This kind of software does not specify the depth.
The depth is determined during the prospecting by the electrode configuration for each layer.
