Map Scale A scale is a statement of the relationship between distances on a map and distances in real life. A drawing that is made according to scale will be an exact copy of the real object, but … This simple concept is complicated by the curvature of the Earth 's surface, which forces scale to vary across a map. Scale is about size, eithe~ relative or absolute, and involves a fundamental set of issues in geography. A map scale is the map distance ratio that corresponds to the actual ground distance. What is the impact and if possible – cost – of the problem(s)? The United States has its borders. Map scale is often confused or interpreted incorrectly, perhaps because the smaller the map scale, the larger the reference number and vice versa. Rock, The Pennsylvania State University. According to the Intergovernmental Committee on Surveying and Mapping, scale defines a mathematical relationship between a map's size and the size of the piece of Earth that is being described. The terms aeronautical chart, geologic, soil, forest, road, and weather map make obvious their respective contents and purposes. 3. A bar scale with the nominal scale, expressed as both "1cm = 6km" and "1:600 000" (equivalent, because 6km = 600 000cm) The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. For example, one may examine how the social forces of a particular area have impacted upon its geographical nature. Map scales and classifications Map scale refers to the size of the representation on the map as compared to the size of the object on the ground. 2.

Every multiple-choice question has five answer choices (A-E), and there are two basic types: A Nominal Scale is a measurement scale, in which numbers serve as “tags” or “labels” only, to identify or classify an object. In rare instances reference may be made to the areal scale of a map, as opposed to the more common linear scale. Update for the 2020/21 academic year.
