The map shows that the area of the island is about two square kilometres. Topographical map grids are worked out in metres, with the grid lines being 1,000 metres apart. 1:100,000 maps are divided into squares representing 1 km 2, each square on the map being one square centimetre in area and representing 1 km 2 on the surface of the Earth.
100km squares Grid square TF. The map shows The Wash and the North Sea, as well as places within the counties of Lincolnshire, Cambridgeshire and Norfolk.. The first letter of the British National Grid is derived from a larger set of 25 squares of size 500 km by 500 km, labelled A to Z, omitting one letter (I) (refer diagram below), previously used as a military grid.

The Line Islands, all of which were formed by volcanic activity, are one of the longest island chains in the world, stretching 2,350 km (1,460 mi) from northwest to southeast. One of them, Starbuck Island , is near the geographic center of the Pacific Ocean ( 4°58′S 158°45′W / 4.97°S 158.75°W / -4.97; -158.75
Township lines run parallel to the baseline (east-west), while range lines run north–south; each are established at 6-mile intervals. Lastly, townships are subdivided into 36 sections of approximately 1 square mile (640 acres; 2.6 km 2) and sections into four quarter-sections of 0.25 square miles (160 acres; 0.65 km 2) each.
The primary grid pattern is of quarter sections (1 ⁄ 2 mi × 1 ⁄ 2 mi (800 m × 800 m)). In U.S. land surveying under the Public Land Survey System (PLSS), a section is an area nominally one square mile (2.6 square kilometers), containing 640 acres (260 hectares), with 36 sections making up one survey township on a rectangular grid.

For example, G0305 means 'square G, 3 km (1.9 mi) east, 5 km (3.1 mi) north'. A location can be indicated to varying resolutions numerically, usually from two digits in each coordinate (for a 1 km (0.62 mi) square) through to five (for a 1 m (3 ft 3 in)) square; the most common usage is the six figure grid reference , employing three digits in ...
This list includes all islands in the world larger than 1,000 km 2 (390 sq mi). For size and location reference, the four continental landmasses are also shown. Continental landmasses Continental landmasses are not usually classified as islands despite being completely surrounded by water. [Note 1] However, because the definition of continent varies between geographers, the Americas are ...
Long Island has been part of the State of New York since 1781, and it is the largest island in the Contiguous United States (48 states). Great Britain – Earlier divided into three or more kingdoms, including England , Wales , and Scotland , and sometimes ruled in part by the Roman Empire and the Danish Empire .
