WebJun 10, 2024 · The purpose of GEOID18 is to return a geoid height that is consistent with the published NAVD 88 orthometric heights on NGS Data Sheets when used with GPS-derived NAD 83 (2011) epoch 2010.0 ellipsoid heights. NGS has chosen to use the term estimated uncertainties which is intended to refer to how well the GEOID18 model performs this task. WebCommercial resistivity instruments are portable devices which are generally capable of investigating the subsurface down to depths of a few hundred metres with high injected currents. These instruments are not customised for long-term installations in remote places. graphtec ce5000-60 year made
