What coordinate system does USGS use?
The UTM (Universal Transverse Mercator) coordinate system divides the world into sixty north-south zones, each 6 degrees of longitude wide.
How do I get UTM coordinates on Google maps?
Degrees, Decimal Minutes: such as 32° 18.385′ N 122° 36.875′ W. Universal Transverse Mercator: such as 10 S 055974, 4282182….

What coordinate system do surveyors use?
SPCS is a system of large-scale conformal map projections originally created in the 1930s to support surveying, engineering, and mapping activities throughout the U.S. and its territories.
What datum does USGS use?
The NAD 83 and the NAVD 88 are the recommended datums to use in USGS publication series information products. The use of these datums establishes a common reference for all horizontal and vertical data in the NSRS for the conterminous United States and Alaska.
Is state plane the same as UTM?
The state plane coordinate system (SPCS) is similar to the UTM system in many respects, but it does have some important differences. In the SPCS, each state has its own zone(s).
How do I read my UTM coordinates?
When reading a UTM coordinate, your reading should state latitude and then longitude (eastings first, then northings). A useful mnemonic to help you remember this is “along the corridor, then up the stairs.”
What map datum is used by most USGS topographic maps?
NAD27
The World Geodetic System of 1984 (WGS84) is identical to NAD83 for most practical purposes within the United States. WGS84 is the default datum setting for almost all GPS devices. But most USGS topographic maps published through 2006 use NAD27.
