The Texas State Plane Coordinate System (SPC) is a coordinate system used to define locations within the state of Texas. It is based on the Universal Transverse Mercator (UTM) projection, which is a conformal projection that preserves angles and shapes. The SPC uses two coordinate zones, one for the northern half of the state and one for the southern half. Within each zone, locations are defined by their easting and northing coordinates. The easting coordinate measures the distance east or west of a central meridian, and the northing coordinate measures the distance north or south of a central parallel. The SPC is used for a variety of applications, including surveying, mapping, and land records.
Best Structure for Texas State Plane Coordinate System
The Texas State Plane Coordinate System (TSPCS) is a system of plane coordinates that is used to define the location of points on the Earth’s surface within the state of Texas. The TSPCS is based on the Lambert Conformal Conic projection, which is a conformal projection that preserves angles and distances at small scales. The TSPCS is divided into two zones, North and South, which are separated by the 32nd parallel north.
Zone Designations
The TSPCS uses the following zone designations:
- North Zone: NAD83 / Texas State Plane North Central Zone (US Feet)
- South Zone: NAD83 / Texas State Plane South Central Zone (US Feet)
Coordinate System Parameters
The following table lists the coordinate system parameters for the TSPCS:
| Parameter | North Zone | South Zone |
|---|---|---|
| Projection | Lambert Conformal Conic | Lambert Conformal Conic |
| Datum | NAD83 | NAD83 |
| Units | US Feet | US Feet |
| Central Meridian | -97° 30′ 00″ W | -99° 00′ 00″ W |
| Standard Parallel 1 | 34° 30′ 00″ N | 29° 30′ 00″ N |
| Standard Parallel 2 | 36° 18′ 00″ N | 31° 06′ 00″ N |
| False Easting | 3,000,000 ft | 3,000,000 ft |
| False Northing | 0 ft | 0 ft |
Applications
The TSPCS is used for a variety of applications, including:
- Surveying
- Mapping
- GIS
- Land records
- Engineering
Advantages
The TSPCS has a number of advantages over other coordinate systems, including:
- It is a conformal projection, which preserves angles and distances at small scales.
- It is based on a national datum, which ensures that it is consistent with other coordinate systems used in the United States.
- It is easy to use and understand.
Question 1:
What is the Texas State Plane Coordinate System (TSPCS)?
Answer:
The Texas State Plane Coordinate System (TSPCS) is a system of coordinates used to locate points on the Earth’s surface within the state of Texas.
Question 2:
How is the TSPCS defined?
Answer:
The TSPCS is defined by two sets of coordinates: northings and eastings. Northings are the distances north of the origin, and eastings are the distances east of the origin. The origin is located at the intersection of the 30th parallel north and the 98th meridian west.
Question 3:
What are the units of measurement used in the TSPCS?
Answer:
The TSPCS uses the United States survey foot as its unit of measurement. One survey foot is equal to 12/39.37 meters.
