Choosing a data type/node to use

Choose the correct data type category to use depending on the kind of data you want to enter or work with:

For this kind of data	Choose this category or data type
DC resistivity	DC resistivity
3D resistivity	3D resistivity
Gravity	Gravity
Microgravity	Microgravity
Magnetotellurics (MT)	Magnetotellurics (MT)
Surface heat flow	Surface heat flow

DC Resistivity

This data type has measured DC Resistivity data (Schlumberger soundings and traverses) and layered models can be stored. Currenly there is no modelling ability within GeoData Manager. However, data can be presented in a range of methods, such as apparent resistivity contouring, and contouring of elevations and thicknesses of selected layers of models from different soundings.

3D Resistivity

This data type has measured 3D Resistivity data.

Gravity

This data type has gravity data.

Microgravity

This data type has microgravity data, comprising benchmark definitions, benchmark repeated measurements and gravity repeat measurements.

Magnetotellurics (MT)

See here for a tutorial on using MT.

There are six MT nodes:

Node	Data set
MT	This node repeats the node below, Sounding
Sounding	The site for a sounding
Impedance	Impedance measurements for a sounding
Resistivity	Resistivity measurements for a sounding
Model	The interpreted 1-D model of resistivity from the above measurements
By Layers	As above, Model, but presents the information with all layers in the header data; this is often more convenient for outputting the data

The interpreted 1-D model has horizontal layers in the ground, and a resistivity for each layer. You can output MT data using Report, Multiple Graph, Map and X-Section.
