Setting up RES2DINV/RES3DINV (DEMO ver.) for the first time

Download DEMO version of RES2DINV from http://www.landviser.net/webfm
Visit hyperlinked pages to download DEMO versions of RES2DINV and RES3DINV and supplemental publications.
Note, that you can use RES2DINV without RES3DINV, but not other way around - RES2DINV have to be installed first. This demo software has decreased functionality, but it might be enough for your research and the DEMO versions never expire.
However, if you decide to purchase software, please request a formal quote from us ASAP before contacting GEOTOMO directly, as we will meet or beat price of other dealers, but we cannot guarantee it unless you secure order from us first.
Now, installing the software…
Click setup.exe and follow directions. When you run through set up series of questions, click OK to the question about dongle installation.
Setup will quit.

Then run the program from Start\Programs\RES2DINV or from folder where it has been installed.

Without a dongle you will see SemiDemo version. Click OK.

Big white screen will be there with menus on the top. If you see white screen only, my guess it is screen resolution on your PC system that makes it blown out of proportion. I did installed mine on VISTA Ultimate 64-bit using same file without any problem before, but today I happen to have Win XP 32-bit computer without RES2DINV, so I run setup.exe on it step by step. Works fine.

Go File/Run Jacobwin if you using a program for the first time. It will calculate partial derivatives for most popular arrays. You will not need to run it again ever on the same computer.


When you decided to purchase and receive your USB dongle in the mail, follow directions to install the dongle published in manual book. You will not need to un-install DEMO versions, the software will pick up dongle if it attached otherwise it will continue to run in semi-demo mode.

If you run into any problems with installation, please, do not hesitate to contact Landviser or post a comment in this blog.

LandMapper® ERM-02 - versatile and affordable

Don’t break your back collecting soil samples. Reduce amount of samples sent for laboratory analysis and save money. And still make detail soil map of your fields, which will be more accurate than conventional soil surveys. Impossible? Not at all with LandMapper ERM-02.

This device measures three important electrical properties of soil: electrical resistivity (ER), conductivity (EC), and potential (EP). Utilizing the most accurate four-electrode principle LandMapper measures ER or EC and helps delineate areas with contrasting soil properties within the fields quickly, non-destructively and cost-efficiently.
In a typical setting, a four-electrode probe is placed on the soil surface and an electrical resistivity or conductivity value is read from the digital display. Using the device prior to soil sampling you can significantly reduce the amount of samples required and precisely design a sampling plan based on the site spatial variability.
Bulk soil EC was correlated with salinity, texture, stone content, total available nutrients, water holding capacity, and filtration rates. Guided by detailed soil EC map obtained with LandMapper, only minimal amount of soil samples is needed to invert EC map into correlated soil properties. Also, LandMapper can be used to measure EC in soil pastes, suspensions and solutions and quickly estimate total dissolved salts (TDS) in solid and liquid samples.
LandMapper ERM-02 was successfully used for non-destructive mapping and monitoring of agricultural fields as well as construction, remediation and archaeological sites.
The device measures ER or EC in soil from 1 inch down to 30 feet, depth is set by changing four-electrode probes of different sizes. Probes can be easily assembled from inexpensive materials available at any hardware store.

Repeat the measurements using series of probes with increasing distances among electrodes and collect detail information about soil horizons, hardpan and groundwater depth. Additional processing of such ER data allows to plot 1D, 2D and even 3D images of subsurface (RES2DINV and RES3DINV software developed by Geotomo is available through Landviser as well).

LandMapper is resistivity meter and datalogger (stores 999 readings), but not a multiplexer, but some researchers from USDA constructed manual multeplexer interface for LandMapper. ERM-02 model has option of directing measurement by PC. Software is being developed by us for multiplexing and monitoring studies with LandMapper.

LandMapper ERM-02 is the most versatile device in LandMapper series and allows you not only measure ER and EC using artificially applied electrical current and four-electrode probes, but also study natural electrical fields in soils and plants with non-polarizing electrodes. Electrical balance between soil and plants is important for plant health; electrical potential gradient governs water and nutrient uptake by plants.

Key Features

• Compact and portable design (weights only 250 g without the probe)
• Fast (one measurement takes 4 sec)
• Accurate (Automatically adjusts electrical resistivity (ER)/conductivity (EC)/potential (EP) ranges to provide best measurement accuracy >99%)

ER= 0.01-1,000,000 Ω m

EC= 0.000 001 – 10 S/m

EP = -1 to +1 V (D=0.01 mV)

• Safe and reliable (uses a standard 9 V battery)
• PC connected for data transfer (stores 999 data values in non-volatile memory)
• Modular and interchangeable (detachable measuring unit accepts mapping 4-electrode probes, sounding cables, laboratory cells, micro-probes, and non-polarizing electrodes)
• Versatile (the same unit can be used for field mapping, measurements in soil, plant and food samples as well as on live plants and animals)
• Affordable (inquire about our very competitive prices and rental rates (US only)  as well as available educational and multiple unit discounts)

Inventory list of Landviser, LLC 2010

I have just updated our inventory/pricing for devices and Res2DINV geophysical software, since GeoTomo increased price for software and also released RES3DINV for 64-bit processors (PC only). Note that GeoTomo Software is based in Malaysia and does not accepts credit cards. They sell their world-renowed geophysical interpretation software directly (wire transfers) and through world network of dealers. Landviser, as a manufacturer of geophysical equipment is an autorized dealer for this software. All dealers are required to quote the same price, however not all accept credit cards and offer free shipping and software support, as Landviser does. Please, consider this before requiring comparison quotes simultaneously from several dealers. If we are not the first dealer served you a quote, software developer might restrict the sale through us and you will have to use wire transfer and purchase directly from GeoTomo.
As I am learning Google Docs and Blogging, I published this document on both places.
