MUDDI

Overview

MUDDI stands for “Model for Underground Data Definition and Integration” and is an approach to make sub-surface data Findable, Accessible, Interoperable, and Re-Usable. The MUDDI Standard defines classes that support the integration of datasets from different types of information about the underground space, using different information models. These information models include models about elements such as utility infrastructure, transport infrastructure, soils, ground water, or environmental parameters. 

MUDDI provides a comprehensive set of concepts that represent relevant features in the sub-surface. The conceptual model defined in the Standard consists of a core of mandatory classes describing built infrastructure networks (such as utility networks) together with a number of optional feature classes, properties, and relationships related to the natural and built underground environment.

The Standard is meant to provide a sufficient level of detail to address application use cases, including but not limited to the following:

• Routine street excavations;
• Emergency response;
• Utility maintenance programs;
• Large scale construction projects;
• Disaster planning;
• Disaster response; and
• Smart Cities programs.

The case for better subsurface data and an explanation of the usefulness of the MUDDI data model is made in this “MUDDI For Everyone” Guide.
