The North Dakota State Water Commission utilizes 4D to manage North Dakotas water resource systems. 4D provides the core framework for the state's overall management initiative with the necessary data management infrastructure and the related application tools to address the complex tasks associated with water resource management. Through supported open standards, the 4D management system has been extended to include records management tools, embedded GIS functionality, complex 2D, 3D, and temporal analysis tools, and web based data dissemination capabilities to provide a robust feature rich management environment.
