GPS - Global Positioning System

Global Positioning System (GPS) is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations.
GPS uses these "man-made stars" as reference points to calculate positions accurate to a matter of meters. In fact, with advanced forms of GPS you can make measurements accurate to a centimeter!
Accounting for urban assets is critical for budgeting and planning purposes. In fact, some Government regulations, such as GASB-34, require regular accurate asset inspections. Planners must also monitor assets to prevent public safety liability.
In September (2002) the GIS department received new 'state of the art' Trimble Global Positioning System equipment. The equipment will allow several City departments to locate, identify and digitally record features to sub-meter accuracy.
