| What is GPS? |
Global positioning systems (GPS) use a constellation of satellites to provide locational information. GPS can determine locations of roads, trails, historic structures or any other features found on the landscape. Information collected with a GPS unit can combine with other geographic data using Geographic Information System (GIS) technology.
