What type of map represents only the horizontal positions of features?

A planimetric map is designed to depict the horizontal position of features on the Earth's surface without representing elevation or relief. These maps focus solely on the portrayal of geographic features such as roads, lakes, urban areas, and boundaries, providing a two-dimensional view of the landscape. The primary purpose of a planimetric map is to offer a clear and simplified representation of lateral positional relationships among various features, making it ideal for tasks like urban planning, land use analysis, and navigation.

In contrast, a bathymetric map illustrates underwater features, particularly the depth of bodies of water, and includes topographic details of the seafloor, which is not purely horizontal positioning. An isohyetal map shows lines connecting points of equal rainfall or other meteorological data, which again includes vertical elements related to precipitation rather than just horizontal positioning. A deciduous map, while less common, would likely pertain to the distribution of deciduous trees or forests, encompassing both horizontal distribution and potentially other characteristics like species variety or density, thus not fitting the criteria of representing only horizontal features.
