An Appraiser's Map, also known as a PLAT, is a map that shows the boundaries of a piece of land and its features. It is typically used by appraisers to determine the value of a property. The PLAT is usually drawn up by a surveyor and includes information such as the size of the land, its shape, and any structures or improvements on the land. It is an important tool for appraisers when assessing the value of a property.
