The shape of a state is determined by the political boundaries and geography that determine its territory, and that shape impacts the politics and economies of the state. [1] The six categories of state shapes are: compact; elongated or attenuated; fragmented; prorupted or protruded; perforated; and compound or complex. [2] [3] [4]
A proportional symbol map or proportional point symbol map is a type of thematic map that uses map symbols that vary in size to represent a quantitative variable. [1]: 131 For example, circles may be used to show the location of cities within the map, with the size of each circle sized proportionally to the population of the city. Typically ...
In cartography, an equivalent, authalic, or equal-area projection is a map projection that preserves relative area measure between any and all map regions. Equivalent projections are widely used for thematic maps showing scenario distribution such as population, farmland distribution, forested areas, and so forth, because an equal-area map does ...
The Köppen climate types of the United States, including the five inhabited U.S. territories) A map of average precipitation across the contiguous United States. Due to its large size and wide range of geographic features, the United States contains examples of nearly every global climate.
The second largest state, Texas, has only 40% of the total area of the largest state, Alaska. Rhode Island is the smallest state by total area and land area. San Bernardino County is the largest county in the contiguous U.S. and is larger than each of the nine smallest states; it is larger than the four smallest states combined.
Map of territorial growth, 1775 Northwest territory Monument referencing the beginning point of the PLSS. Originally proposed by Thomas Jefferson to create a nation of "yeoman farmers", [1] the PLSS began shortly after the American Revolutionary War, when the federal government became responsible for large areas of land west of the original thirteen states.
The invention of the Lambert cylindrical equal-area projection is attributed to the Swiss mathematician Johann Heinrich Lambert in 1772. [1] Variations of it appeared over the years by inventors who stretched the height of the Lambert and compressed the width commensurately in various ratios.
The first way is the ratio of the size of the generating globe to the size of the Earth. The generating globe is a conceptual model to which the Earth is shrunk and from which the map is projected. The ratio of the Earth's size to the generating globe's size is called the nominal scale (also called principal scale or representative fraction).
