Which of the following is NOT a type of legal description of land?

A topographical map is primarily a graphical representation that illustrates the physical features of an area, such as terrain, elevation, and landforms. While it provides valuable information about the landscape, it does not serve as a legal description of land for property rights or boundaries. Legal descriptions are more precise and structured formats used to identify the exact location and extent of a parcel of land within a legally recognizable framework.

In contrast, metes and bounds is a method that describes land using physical features, distances, angles, and directions. The government rectangular system, also known as the Public Lands Survey System, uses a grid of townships and sections to define land locations in a standardized way. Lot, block, and subdivision plats represent land divisions specific to housing developments or other plotted areas, providing clear descriptions tied to a parcel's location relative to other plots.

Therefore, while metes and bounds, the government rectangular system, and lot, block, and subdivision plats are all established methods for legally describing land, a topographical map does not fulfill that role, making it the correct choice for this question.
