What type of data is primarily gathered through cadastral surveys?

Cadastral surveys are specialized type of surveys that focus on determining and documenting the boundaries, ownership, and land use of various parcels of property. The primary purpose of these surveys is to create a legal record of land parcels for ownership and taxation purposes, which includes precise measurements that define where one property starts and another ends. This data is crucial for real estate transactions, land management, and urban planning, ensuring that land rights are clearly established and disputes can be minimized.

In contrast, demographic statistics involve the study of populations and their characteristics, which is not the focus of cadastral surveys. Climate data pertains to atmospheric conditions and environmental factors that do not directly relate to land ownership or boundaries. Infrastructure measurements concern the dimensions and positioning of physical structures like roads, bridges, or utilities, rather than property lines or land use. Therefore, the information collected through cadastral surveys is distinctly about property boundaries, ownership, and land use, making it the correct choice.
