\nthe we can produce 2D section (and level maps from the appropriate data). If there is topography information throughout the profile it is used in the inversion process. Click for contact<\/a>.<\/span><\/p>\n

3D modelling<\/strong><\/p>\n


\nSynthetic VES data is created over the expected model to provide preliminary information to see how much information you will obtain from field work, the effect of environmental geology and some occurrence (lakes, seas, etc.), and to design the survey plan. Click for contact<\/a>.<\/p>\n
