What map projections are used in state plane coordinates?
The State Plane coordinate system is based on two types of map projections: the Lambert conformal conic and the transverse Mercator projections.
Is state plane the same as UTM?
Because SPCS needs such a high level of accuracy, it divides the United States into 124 zones, each with a projection of its own. Overall, the State Plane Coordinate System minimizes distortion (compared to the UTM system) because of the smaller zone sizes.
What is the purpose of state plane coordinate system?
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 units are state plane coordinates?
The standard unit of measure for SPCS 27 is the U.S. survey foot. For SPCS 83, the most common unit of measure is the meter. There are two standard used in the U.S. to convert between feet and meters. Those states that support both feet and meters have legislated which feet-to-meters conversion they use.
Is state plane a geographic coordinate system?
The State Plane Coordinate System (SPCS) is a set of 124 geographic zones or coordinate systems designed for specific regions of the United States. The system is widely used for geographic data by state and local governments. Its popularity is due to at least two factors.
Which coordinate system is used by India?
The Indian Grid uses the Lambert Conformal Conic Projection system (also known as Conic Orthomorphic Projection) with 2 Standard Parallels.
How are state plane coordinate system zones determined?
A Cartesian coordinate system is created for each zone by establishing an origin some distance (usually 2,000,000 feet) to the west of the zone’s central meridian and some distance to the south of the zone’s southernmost point. This ensures that all coordinates within the zone will be positive.
What are plane coordinates?
The coordinate plane is a two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis. The two axes meet at a point called the origin. We can use the coordinate plane to graph points, lines, and more.
Is nad83 a state plane coordinate system?
U.S. State Plane Zones (NAD 1983) represents the State Plane Coordinate System (SPCS) zones for the 1983 North American Datum in the United States.
How are SPCS zones determined?
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). The number of zones in a state is determined by the area the state covers and ranges from one for a small state such as Rhode Island to as many as five.
What is a state plane projection?
State Plane Coordinate System (SPCS) is not a projection (also known as SPC, State Plane, and State). It is a coordinate system that divides the 50 states of the United States, Puerto Rico, and the U.S. Virgin Islands into more than 120 numbered sections, referred to as zones.
What is a state plane?
The State Plane Coordinate System ( SPS or SPCS) is a set of 124 geographic zones or coordinate systems designed for specific regions of the United States. Each state contains one or more state plane zones, the boundaries of which usually follow county lines.
What is the Texas coordinate system?
The official coordinate system is defined as “the standard system of coordinates and elevations based upon the National Oceanic and Atmospheric Administration data known as the Texas State Plan Coordinate Grid System of 1983…”.
