What type of coordinate system is needed to create boundary lines of land parcels?

To create boundary lines of land parcels, a projected coordinate system is essential. This type of system enables the representation of the Earth's three-dimensional surface onto a two-dimensional flat map while preserving specific properties such as area, shape, or distance, depending on the projection used.

Land parcel boundaries often require accurate measurements and precise positioning, both of which are best supported by a projected coordinate system. For example, projected systems like State Plane or UTM (Universal Transverse Mercator) are specifically designed for use over smaller areas and are tailored for accuracy in specific regions, making them ideal for land surveying and property delineation.

In contrast, a geographic coordinate system, which is based on latitude and longitude, may not provide the necessary detail or accuracy when it comes to depicting smaller land areas. Global coordinate systems generally refer to methodologies for referencing locations anywhere on Earth, but they do not facilitate the localized measurements crucial for boundary line delineation. Cartographic systems, while important for the design of maps, focus on visual representation rather than the precision required for land parcel boundaries. Hence, the projected coordinate system is the most suitable choice for this purpose.
