Cadastral Surveys are conducted to establish the exact location, boundaries, or subdivision of a tract of land in any specified area. This type of survey requires professional registration in all states. Presently, land surveys generally consist of the following chores:

• Establishing markers or monuments to define and thereby preserve the boundaries of land belonging to a private concern, a corporation, or the government.
• Relocating markers or monuments legally established by original surveys. This requires examining previous survey records and retracing what was done. When some markers or monuments are missing, they are re -established following recognized procedures, using whatever information is available.
• Rerunning old land survey lines to determine their lengths and directions. As a result of the high cost of land, old lines are premeasured to get more precise measurements.
• Subdividing landed estates into parcels of predetermined sizes and shapes.
• Calculating areas, distances, and directions and preparing the land map to portray the survey data so that it can be used as a permanent record.
