This new edition of "Brown's Boundary Control and Legal Principles", the classic surveying and land law reference is significantly revised to reflect the latest advances in the field, while providing new insights into the historic basis for boundary determinations. It addresses new changes to laws of boundary evidence; locating easements and reversions; and ownership, transfer, and description of real property. The latest information on the technologies advancing boundary law is covered, including Geographic Information Systems (GIS) and Global Positioning Systems (GPS), and their impact on surveying measurements. A wealth of case studies on federal and state nonsectionalized land surveys demonstrates real world examples of covered material.
