What type of data do State Plane and UTM systems represent?

State Plane and UTM (Universal Transverse Mercator) systems represent projected data because they are coordinate reference systems designed to represent the curved surface of the Earth in a flat, two-dimensional form. These systems transform geographic coordinates (latitude and longitude) into a flat plane, allowing for more accurate distance and area calculations for mapping purposes.

Projected data is specifically created using mathematical transformations that provide a way to visually represent geographic features on maps. This includes defining how coordinates are represented in terms of X and Y values in a Cartesian plane. In localized areas, State Plane systems use specific projections tailored to minimize distortion within that area, while UTM employs a series of zones to represent locations in a standardized manner.

Geodetic data refers to more general and broader calculations of earth dimensions and positions, which do not focus specifically on planar representation. Raster data represents information in a grid format, often used for images or surface models, while vector data consists of points, lines, and polygons that represent real-world features but also do not reference the projection aspect directly. Therefore, the classification of State Plane and UTM as projected data is accurate, emphasizing their purpose in accurately depicting geographic information in a usable format for mapping and spatial analysis.
