Which Geometry Type should a city planner select to reflect changes in length for new construction on streets?

The selection of the Polyline geometry type is appropriate for representing linear features such as streets, roads, or paths in a geographic information system (GIS). When city planners need to reflect changes in length due to new construction on streets, Polylines serve this purpose effectively because they are designed to represent one-dimensional features with length, allowing for changes in geometry that accurately depict the actual configurations of streets.

Polylines can easily be modified to accommodate additions, alterations, or re-alignments in street construction, enabling planners to maintain up-to-date and accurate information about the network of streets. The continuous nature of Polylines also makes it possible to depict pathways that may have curves or bends, reflecting their real-world application.

In contrast, other geometry types would not serve adequately for this purpose. Multipoint is geared toward representing multiple singular points rather than a line. Polygon is used for area features that encompass a breadth, such as parks or building footprints, making it unsuitable for linear street changes. Multipatch is primarily used for 3D geometries, which again do not fit the requirements for representing changes in street lengths effectively.
