Final answer:
The key to automated registration of land is an accurate determination of property dimensions and calculation of acreage using property maps and the metes and bounds system. Some states have implemented online registration systems, but concerns about voter fraud and security have led to a preference for traditional paper registration.
Step-by-step explanation:
The key to automated registration of land is the accurate determination of property dimensions and calculation of acreage. This process involves using property maps and the metes and bounds system, where property lines are demarcated by moveable objects like trees, rocks, and streams. In some cases, states have implemented online registration systems to make the process easier and safer, but concerns about voter fraud and security have led some states to favor traditional paper registration.
