What is the name of the mapped record that provides an overall, low-detail picture of the entire distribution system?

The mapped record that gives an overall, low-detail picture of the entire distribution system is referred to as a comprehensive map. This kind of map captures the general layout and major components of the water distribution system, allowing for a broad understanding of how different parts of the system are interconnected. It provides essential information at a macro level, which is helpful for planning, maintenance, and management of the distribution system.

In contrast, sectional maps focus on specific areas in greater detail, while a detailed layout would show intricate components and features of the system. A distribution overview can imply various interpretations of system details, but it does not commonly refer to a mapped record status. Therefore, the term "comprehensive map" accurately encompasses the need for a low-detail, holistic view of the entire distribution system.
