Geo-Equipment

Landviser develops innovative non-invasive technologies (hand-held equipment and software) for mapping and monitoring core biosphere components: soils, plants and groundwater. We provide custom research system integration and consulting on electrical geophysics applications in agriculture, civil and environmental engineering, archaeology and forensic, hydrological and geological prospecting; GIS; geostatistics; and remote sensing.
Depending on your project we can assist with equipment/software procurement and develop training courses in geophysical equipment (LandMapper, SibER - electrotomography, AEMP - electromagnetic scanner, etc) and software (GIS, seismic and resistivity imaging).
We are an international consulting company with headquarters in Texas, USA and business contacts in Russia, Canada, Malaysia, Indonesia, Philippines, Middle East, China and South America. Landviser - Enlightening Research

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 ERM-02 - new handheld EC/ER/SP meter

LandMapper - field EC meter with lab accuracy*We have a new bath of LandMappers ERM-02 in stock! Please, contact us info@landviser.com or +1-609-412-0555 / 888-306-LAND to discuss suitability of ERM-01 or ERM-02 for your applications.  *******

LandMapper ERM-02 is a newest device in the product line of Landviser, LLC. This portative device can measure three important electrical properties of solid, semisolid, and liquid media: electrical resistivity (ER), conductivity (EC), and potential (EP). Using the most accurate four-electrode principle LandMapper ERM-02 measures ER or EC to help new deviceyou to delineate areas with contrasting soil properties within the fields quickly, non-destructively, and cost-efficiently. 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.

The device measures electrical resistivity or conductivity in a surface soil layer of the depth from 2 cm down to 20 m, which is set by varying the size of a four-electrode probe.

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 (self-potentials) and plants (bio-potentials) with patented non-polarizing electrodes. Electrical balance between soil and plants is important for plant health and electrical potential gradient governs water and nutrient uptake by plants. Monitoring of electrical potentials in plants and soils is a cutting-edge research topic in the leading scientific centers around the world.

small hills

For not big changes in elevation along the survey line you can assume the flat conditions. For bigger hills, there is an options to input elevation (Z) to the .DAT file. Remember, though, that DEMO version of the software does not takes into account elevation. If you don't have professional license but need data analysed with topography, email us and we can process them for a small fee.

Resinv2d

Thank you for your resinv2d demo software, but i wonder that how we can create a DAT file for reading data file in resinv2d. Please help me with that. Thanks you so much

create .DAT file

Most geophysical equipment software has option to convert measured data to RES2DINV format. In addition RES2DINV has option to import data from most equipment. If none possible, read and follow instructions in http://landviser.net/content/formatting-array-input-data-file-res2dinv-surface-electrodes-any-geometry .DAT is a text file and you can edit it in MS Notepad and/or Excel.

Resistivity

First of all, thanks for your website, it's so helpful for me. after that, i don't understand some problems: I have two questions for you. How we can measure or handle the data when we do on the uneven surface or small hills, The resistivity will be change, is that right? and How we create the File.dat befor for running the res2dinv. Thanks. Have a nice day!

honestly, you do have

honestly, you do have wonderful equipments. but i want to know if the land mapper 01 & 02 can be used for underground water investigation to a depth of about 100m. I will also like you to send me the free 1D VES software and the price list for Landmapper and SibER resistivity surveying set. thanks.

LandMapper 01 and 02 can be

LandMapper 01 and 02 can be used for investigations down to about 30 m. For the depths beyond that you would need SibER 48 with appropriate cable sets. Cable set of 20 m spacings can measure resistivity and induced polarization (combination of parameters usefull for groundwater search) down to about 300 m. Current availability and pricing information can be downloaded from this link http://www.landviser.net/webfm_send/29 (registered users).
