The Map module provides a suite of tools for using feature objects to build conceptual models.

Feature objects are used to provide some GIS-like capabilities within GMS. Feature objects include points, arcs, and polygons. Feature objects can be grouped into layers or coverages. Multiple coverages and conceptual models can exist in a single GMS project. A set of coverages can be constructed representing a conceptual model of a groundwater modeling problem. This high level representation can be used to automatically generate numerical models such as MODFLOW and MT3DMS. Feature objects can also be used for automated mesh generation.

The Map module is often used as a starting point for many project. Often, a project starts with an image then, on a coverage, the module tools are used to create feature objects over the image to represent boundaries and structures. Then the feature objects are converted to other data types for further processing.

For the purpose of converting feature objects to 2D or 3D grids, the module contains a grid frame tool to define the boundaries and properties of the grid being created.

The Map module also contains its own menu commands and its own display options.

The Map module, including the conceptual modeling tools, is included with all paid editions of GMS.
