Delaware–Maryland–Pennsylvania Tri-State Point
The Delaware–Maryland–Pennsylvania Tri-State Point is the meeting of the northwestern corner of Delaware, the northeastern corner of Maryland, and the southern edge of Pennsylvania. A wooden marker was placed in 1765, by Charles Mason and Jeremiah Dixon, and was replaced with a stone marker in 1849. The tripoint site contributes to the Delaware Boundary Markers historic district, listed on the National Register of Historic Places in 1975. A trail to the marker was made in 2014–2015. History Mason and Dixon placed a wooden marker on the tri-point on June 6, 1765. It was replaced in 1849 by a stone marker. At one point, the marker went missing, so Lt. Col. James Duncan Graham, of the U.S. Corps of Topographical Engineers, was sent out to replace it. He located the marker, but replaced it in the wrong location. In 1892, W.C. Hodgkins was sent to resurvey the area, and he fixed the location of the marker. He also set the Arc Corner Monument, part of the resolution of the Delaw ...

Surveying Of The United States
Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as the designated positions of structural components for construction or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. A professional in land surveying is called a land surveyor. Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, GNSS receivers, retroreflectors, 3D scanners, lidar sensors, radios, inclinometer, handheld tablets, optical and digital levels, subsurface loca ...

List Of Tripoints Of U
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole".Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of ''The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help us ...

Delaware Wedge
The Wedge (or Delaware Wedge) is a tract of land along the borders of Delaware, Maryland and Pennsylvania. Ownership of the land was disputed until 1921; it is now recognized as part of Delaware. The tract was created primarily by the shortcomings of contemporary surveying techniques when the boundaries were defined in the 18th century. It is bounded on the north by an eastern extension of the east–west portion of the Mason–Dixon line, on the west by the north–south portion of the Mason–Dixon line, and on the southeast by the Twelve-Mile Circle around New Castle, Delaware. The crossroads community of Mechanicsville, Delaware, lies within the area today. History Colonization and establishment of ownership The original 1632 charter for the Province of Maryland gave the Calverts what is now called the Delmarva Peninsula above the latitude of Watkins Point, Maryland up to the 40th parallel. A small Dutch settlement, Zwaanendael (1631–32), was within their territory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
