Shift of the world's economic center of gravity since 1980 and projected until 2050 [7] Various definitions of geographical centres exists. The definitions used by the references in this article refer to calculations within the 2 dimensions of a surface, mainly as the surface of Earth is the domain of human cultural existence.
Republic Act No. 9522, "An Act to Define the Baselines of the Territorial Sea of the Philippines", [66] describes an irregular polygon which fits within a box with its center at 121°44'47.45"E 12°46'6.1252"N, a point also roughly in the center of the Tablas Strait.
The Encyclopedia of Triangle Centers (ETC) is an online list of thousands of points or "centers" associated with the geometry of a triangle. This resource is hosted at the University of Evansville. It started from a list of 400 triangle centers published in the 1998 book Triangle Centers and Central Triangles by Professor Clark Kimberling. [1]
This is a complete list of cities and municipalities in the Philippines. The Philippines is administratively divided into 82 provinces ( Filipino : lalawigan ). These, together with the National Capital Region , are further subdivided into cities (Filipino: lungsod ) and municipalities (Filipino: bayan ).
In geography, the centroid of the two-dimensional shape of a region of the Earth's surface (projected radially to sea level or onto a geoid surface) is known as its geographic centre or geographical centre or (less commonly) gravitational centre.
In mathematics and physics, the centroid, also known as geometric center or center of figure, of a plane figure or solid figure is the arithmetic mean position of all the points in the surface of the figure. [further explanation needed] The same definition extends to any object in -dimensional Euclidean space. [1]
