Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Langlee Island island in the United States of America

Langlee Island or Langley Island is an island in the Hingham Bay area of the Boston Harbor Islands National Recreation Area. The island has a permanent size of 4 acres (16,000 m2), plus an intertidal zone of a further 3 acres (12,000 m2), and is composed of a massing of Roxbury puddingstone which rises to a height of 40 feet (12 m) above sea level.

Silver Lake is a 640-acre (2.6 km2) lake in Pembroke, Kingston, and Plympton, Massachusetts, south of Route 27 and east of Route 36. The Pembroke/Plympton town line is entirely within the lake, and a portion of the western shoreline of the lake is the town line with Halifax. It used to be called the Jones River Pond, but its name was changed to Silver Lake in the 1800s in a marketing effort to sell more ice from it. The lake is the principal water supply for the City of Brockton, whose water treatment plant is on Route 36 in Halifax. The inflow of the pond is Tubbs Meadow Brook, and the pond is the headwaters of the Jones River. Occasionally water is diverted into Silver Lake from Monponsett Pond in Halifax and Furnace Pond in Pembroke whenever there is a water shortage. Although the lake is a reservoir, which prevents recreational activities to keep the drinking water clean, the water from the diversions are not and can pump in contaminated water. Monponsett Pond in particular has reoccurring toxic algae growths which get transferred into the lake. It is supposed to be the main source of the Jones River by contributing aboot twenty percent of the river's flow, but the Forge Pond Dam near its base lets out minimal, some years no, water to the river. This also prevents migratory aquatic animals from reaching the lake. Brockton prefers to keep the dam to have more accessible water. Access to the pond is through Silver Lake Sanctuary, a 92-acre (370,000 m2) property where one can walk, hike and fish, which is located at the end of Barses Lane, off Route 27 in Kingston.

Scituate Proving Ground was a proving ground of the United States Army located in Scituate, Massachusetts. It was operational from 1918 when 115.25 acres were purchased between June and July. In November 1919, the site was declared excess, and it was used as a storing ground until June 1921. During its brief period of operation it was intended to proof fire the production of 155mm and 240mm howitzer carriages that were built elsewhere in Massachusetts. The proving grounds in Scituate did not have the ability to test the projectiles or fuses, so it was used to test cartridge cases, primer and powder. The grounds had its own heating and power plants as well as a garrison of 10 officers and 130 enlisted men. Recently, the site was used for housing, although former structures dating from the use of the grounds could be seen up until 2018, when the Toll Brothers began to develop the site. Toll Brothers plans to build 'Seaside at Scituate' which will have 142 townhouses in a condo setting for people 55 years and older when completed.
