A geometric boundary, also known as a geometric border, is a line segment that is constructed by an arc or a straight line, regardless of the topography or cultural heritage of the area it traverses. Examples include the U.S.-Canada border and the borders of a few former colonial African governments.
After the 1500s, geometric cartography—also known as scientific cartography—progressed throughout Europe. Before establishing borders on the ground, borders must first be drawn on the map.
Here are some instances of various boundary kinds.
Boundary defined by natural elements such as rivers, mountain ranges, or deserts.
