The Maps module is used to create and display contoured and color-filled maps to represent the value types associated with a broad range of geophysical survey data including MT, TDEM, Gravity, Magnetics and Wells. The program can be used to extract and grid both observed and modelled parameters, for example, phase at 10 Hz on the basis of single station MT data, resistivities at 500 m below sea level on the basis of a 3D MT model or pressure at a specific depth extracted from well stations.

Maps provides numerous functions for controlling map gridding and display, for printing, and for constructing the profiles used in many of WinGLink's other modules. The module allows for the simultaneous display of stations from different surveys as well as the construction of integrated maps.
