All of us at Landviser, LLC (USA) and IP GeoPro (Russia) are wishing our friends, collegues, customers and everybody else around the world Happy Holidays and a Great New Year! Looking forward to change, trust and fairness for all in 2017!!! We, as a small geo-consulting company, would continue to do our best in studying our Morther Earth and bringing Joy to the World!

All of us at Landviser, LLC (USA) and IP GeoPro (Russia) are wishing our friends, collegues, customers and everybody else around the world Happy Holidays and Great New Year!

Landviser develops and sells unique hand-held geophysical devices and powerful electrical geophysical equipment. We are collaborating with KB "Electrometry", Russia and GeoTOMO Software, Malaysia.

Manual measuring of electrical resistivity 2D cross-section is possible with LandMapper with supplied (optional) or made by user cable set.

There are two modifications of 2D cable set offered and tested by Landviser, LLC:

1. Mobile shallow (~2 m depth) set consisted of two T-style probes (AB and MN dipoles) similar to mapping probes. The dipoles are set at 1 m size with possible separation between dipoles (wire length) no more than 5 meters (n=5).
2. Stationary set (~ 14 m depth) where electrodes are hammered on the soil surface along the straight line at one meter distance. Electrodes are simple metal spikes/nails and is sourced locally (are NOT provided by Landviser, LLC). We supply wires with banana-plug connections to LandMapper terminals on one end and alligator clips on the other end to connect with electrodes.

Principle of measurements with both sets is the same for both cable sets and is illustrated by figure below. You can also watch instructional videos on our YouTube Channel - LandviserLLC

Presentation, embedded below was developed to bring users up to speed in interpretation of their resistivity data. Class for end users was conducted in Indonesia and included training on field data collection with SibER-48 using ~ 900 m long profile in Wenner-Schlumberger and pole-dipole (remote electrode) 2D tomography. On the second day users received hands-on instructions on data import into RES2DINV software, quality assurance of the data based on visual approach as well as through RMS of the interpretation model. 

General discussion about non-uniquness of the subsurface interpretation modl for 1D, 2D, and 3D representations has followed this class.

Dr. Larisa Golovko (President of Landviser, LLC) will be presenting "Geophysical Methods of Electrical Resistivity and Self-Potential in Agriculture" in first of 

Agricultural Geophysics Webinar Series: "Application of Geophysical Methods to Agriculture: Methods Employed"

A live webinar on the application of geophysics to agriculture will be offered on:

Tuesday, February 18, 2014, from 3pm - 4:30pm EST
(2:00 - 3:30 CST, 1:00 - 2:30 MST, 12:00 - 1:30 PST)

This first in a series of agricultural geophysics webinars will focus on the near-surface geophysical methods presently being used for agricultural purposes, which include resistivity, self-potential, electromagnetic induction, ground penetrating radar, dielectric sensors, VIS/NIR/MIR spectrometry, gamma ray spectrometry, mechanical soil compaction sensors, and ion selective potentiometry. Five presenters will provide a short overview of agricultural geophysical methods during the first 30 minutes of the webinar. The last hour of the webinar will be devoted to a panel discussion with the presenters, who will answer questions from the audience.

Dear visitors, clients, collegues and friends!

Landviser LLC is wishing you Happy, Healthy and Prosperious 2014! Let all your ideas to develop into innovative products and services to create more Joy on our planet Earth and gain yet more understanding about our World. We continue to develop and test our equipment for different environmental applications in collaboration with leading research organizations worldwide. This year we would like to congratulate Department of Soil Physics and Reclamation in Moscow State University (M.V. Lomonosov), Faculty of Soil Science with 70th Anneversary:

Also, this year we added two innovative geophysical devices to our offerings in collaboration with OOO Electrometry and Gelion holding (Russia):

Electromagnetic multi-frequency profiler AEMP-14

Electrical tomography SibER-48 equipment

Do not hesitate to ask us about applications of geophysics in archaeology, agriculture, and environmental sciences. We are here to "Enlighten Your Research".
