A cartographic representation detailing the three-dimensional terrain of the state, including elevation changes, natural features such as rivers and forests, and man-made structures. These maps employ contour lines to depict elevation, with closer lines indicating steeper slopes and wider spacing representing gentler gradients. For example, a specific area might show a series of tightly packed contour lines indicating a bluff alongside a river, while a broader, more open area displays a relatively flat agricultural plain.
These detailed cartographic depictions are invaluable for a variety of purposes. They support infrastructure planning by identifying suitable locations for roads, bridges, and buildings, taking into account the terrain’s impact on construction and potential environmental effects. Resource management benefits through the delineation of watersheds, forested areas, and mineral deposits. Furthermore, these maps provide crucial information for recreational activities such as hiking, camping, and fishing, enabling users to navigate the landscape safely and effectively. Historically, they have played a crucial role in surveying and land management, providing a lasting record of the state’s physical landscape.
