The device measures ER or EC in soil from 1 inch down to 30 feet, depth is set by changingР’В four-electrode probes of different sizes. LandMapper ERM-02 was successfully used for non-destructive mapping and monitoring of agricultural fields as well as construction, remediation and archaeological sites. 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. 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. 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.Р”В«ulk soil EC was correlated with salinity, texture, stone content, total available nutrients, water holding capacity, and filtration rates.

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. 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. This device measures three important electrical properties of soil: electrical resistivity (ER), conductivity (EC), and potential (EP). Impossible? Not at all with LandMapper ERM-02. And still make detail soil map of your fields, which will be more accurate than conventional soil surveys. Reduce amount of samples sent for laboratory analysis and save money. Supports time-lapse inversion.DonРІР‚в„ўt break your back collecting soil samples.

The software has a number of features for optimising the least-squares routine for faster completion on large datasets.

RES3DINV is capable of inverting 3D apparent resistivity volumes measured using a regular grid of surface electrodes and is a powerful tool for resoling complex buried structures. 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. The software package is fully automated and advises the user on what modal and inversion parameters are applicable for the dataset, or how parameters should be adjusted.Р”Р„ least-squares routine is used to perform the inversion and RES2DINV permits the user to adjust the style of the inversion routine as well as key parameters like the dampening factor. LandMapper ERM-02 was successfully used for non-destructive mapping and monitoring of agricultural fields as well as construction, remediation and archaeological sites. RES2DINV is one of the most common inversions packages for calculating 2D Resistivity and Chargeability models. Resistivity model created using RES2DINV. In order to interpret variations in the electrical properties, and create a ground modal, it is necessary to mathematically calculate the subsurface conditions required to produce an equivalent dataset to the one recorded by the instrument- this is called inversion. The recorded Apparent Resistivity is represented as a point measurement in the dataset. As a result the each resistivity measurement represents the bulk resistive properties of the ground- referred to as the Apparent Resistivity. Resistivity measurements rely on expanding the electrode separation in order to achieve ever deeper measurements, leading to a larger volume of the subsurface material being sampled for each successive depth level.
