LandMapper ERM-01 - simple handheld resistivity meter

Throw away your augers and soil samplers! Well, not quite... LandMapper® ERM-01 is new non invasive device, which will help you to map land parcels with contrasting soil properties within the fields quickly, non destructivelyand cost-efficiently.

Landmapper is an excellent tool for soil mapping required for environmental consulting, golf courses maintenance, construction services, farm management, new land development, and real-estate planning. It is a must have tool for forensic and archaeological investigators, even for serious treasure hunters. Using this non invasive 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.

LandMapper® ERM-01 measures electrical resistivity or conductivity of soils and related media for express non invasive mapping and monitoring of agricultural fields as well as construction and remediation sites. In a typical setting, a four-electrode probe is placed on the surface and an electrical resistivity value is read from the digital display. The device measures electrical resistivity in a surface layer of the depth from 2 cm down to 20 m, which is set by varying the size of a four-electrode probe. Measurements are based on well-known four-electrode principle, which allows to avoid influence of electrode contact potential on measured electrical conductivity or resistivity of the media and obtain accurate readings.  The field tests were performed by our customers in USA, Russia, China, Canada, Sweden, France, Germany, Iraq, Dubai, Brazil, Panama and many others.

LandMapper, NEP, and Self-Potential methods for Forensic and Archaeological Applications

detect burial places under uniform grass

Four-electrode probe for detection of burial places of criminal origin

We used electrical geophysical methods to measure the disturbance of the soil together with the properties of a hidden object itself. The study was conducted in collaboration with Russian Ministry of Internal Affairs to test methods for fast outlining soil disturbance places to help criminological search. The method is based on measurements of soil bulk electrical resistivity and principles of soil formation.

 

complex geophysical investigations in Kiev, Ukraine

Electrical geophysical methods to study subsurface water movement in urban areas

Hazardous hydrological situation caused by unknown factors appeared in Kiev-Pechersk Lavra (Kiev, Ukraine) near The Church of Holy Cross Elevation in 1987. The problem was attributable to temporary subsurface water fluxes fed by precipitation. Methods of 4-electrode profiling, vertical electrical sounding, and self-potential were utilized.

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

Download DEMO 32-bit version of RES2DINV and RES3DINV from attached files below this post or download DEMO versions of RES2DINV and RES3DINV. Supplemental publications and other versions of software (legacy or 64-bit) are available for registered users from the respective folders (RES2DINV and RES3DINV) under SUPPORT/Downloads section of this website. You have to login before you can acces the Downloads repository (see more here)

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.
