Examples of arcs drawn over DEM data in the Map module

The Map Map Module Icon.svg module provides a suite of tools for defining watershed data using feature objects: points, arcs, and polygons. It is accessed by clicking the Map Module Icon.svg icon on the Module toolbar. These feature objects are grouped onto coverages, similar to a layer or level in a CAD drawing. Each coverage represents a particular set of information. For example, one coverage could be used to define drainage boundaries, and another coverage could be used to define land use and soil zones.

Land use and soil zones can be used to compute curve numbers or map other important modeling parameters for hydrologic analysis. Other examples of coverage usage include:

The Map module uses the information to directly create and manage hydrologic and hydraulic models. The map tools can also be used as a support utility for data development with either TINs or DEMs. Results of watershed and floodplain delineations can be saved in the map module and converted to GIS data layers for export.

Background maps from the GIS and Terrain Data modules can be used as guides for digitizing feature objects in the Map madule. A rough boundary and stream network can also be used to generate a TIN or two-dimensional finite difference grid that conforms precisely to streams and other important hydrologic features.

The Map module is included with all editions of WMS.
