What does a bench marker indicate regarding government property?

A bench marker specifically provides critical geographic information, including elevation and location coordinates. These markers are intricately used in surveying and mapping to establish precise points in a geographic layout, which is crucial for tasks such as construction, land development, and floodplain management.

By indicating elevation, bench markers help in understanding the topography of a region, which is essential for drainage, development, or any construction projects that require knowledge of land contours. Moreover, having location coordinates allows for accurate navigation and positioning on maps, aiding in various governmental and engineering applications.

In this context, the other options do not accurately represent the primary function of a bench marker. While property ownership and boundaries are important in land management, they are usually confirmed through deeds and surveys, not exclusively through bench markers. Additionally, the type of property use is determined by zoning laws and land-use regulations, which are separate considerations from the purposes served by bench markers.
