A ______ is a professional on-site measurement of lot lines, dimensions, and elements of a property.

A survey is a professional on-site measurement that involves determining the boundaries, dimensions, and various elements of a property. It provides critical information about the exact location of lot lines, which is essential for understanding property rights, potential limitations, and zoning regulations. Surveys can also include details about easements, encroachments, and other significant features of the land.

In the context of real estate, accurate surveys are crucial because they help resolve disputes over property boundaries and can inform future development or improvements. Unlike inspections, which typically assess the condition and quality of a structure, or appraisals, which evaluate the value of the property, surveys specifically focus on the spatial and legal aspects of the land. Abstracts refer to a summary of property ownership and liens, which is a different concept altogether. Therefore, a survey stands out as the correct term for a professional measurement of a property's lot lines and dimensions.
