Who set and determined the Texas State Plane Coordinate system?

The Texas State Plane Coordinate System was established and determined by the National Geodetic Survey (NGS). This organization is responsible for maintaining the nation’s geodetic framework, which provides consistent and precise geographic references, including coordinate systems specific to states. The NGS develops the mathematical models and boundary definitions necessary for creating state plane coordinate systems, ensuring they meet federal and national standards for geospatial accuracy.

The other choices may relate to various aspects of surveying and geographic data but do not specifically hold the authority or the role in formally defining the Texas State Plane Coordinate System. For instance, the Texas Land Surveying Association primarily focuses on the interests of land surveyors and does not engage in defining coordinate systems. The National Oceanic and Atmospheric Administration encompasses a broader range of environmental and atmospheric data and does not focus specifically on land surveying and coordinate standards in the same manner as the NGS. Similarly, while the Texas Department of Transportation may implement and utilize these systems for mapping and infrastructure planning, it does not carry out the foundational process of setting or determining the coordinate system itself.
