What is a detailed map showing the boundaries of individual parcels, streets, easements, and other associated data called?

A detailed map that illustrates the boundaries of individual parcels, streets, easements, and other relevant data is referred to as a plat. This type of map provides crucial information regarding land divisions and is often used for legal purposes, such as when subdividing property or recording land ownership.

Plats are typically created by surveyors and must adhere to specific legal standards. They facilitate an understanding of how land is organized and can be essential for real estate transactions, zoning processes, and municipal planning.

Other options like a survey primarily focus on measuring land and features but do not always provide the extensive layout seen in a plat. Blueprints are generally used in construction and architecture to depict building designs rather than land boundaries. A site plan may show the layout of a property and its improvements but doesn't typically encompass the detailed boundary information of multiple parcels as comprehensively as a plat. Therefore, the plat is the correct term for this specific type of detailed map.
