History of the National Register of Historic Places
The History of the National Register of Historic Places began in 1966 when the United States government passed the National Historic Preservation Act, which created the National Register of Historic Places. Upon its inception, the U. S. National Park Service became the lead agency for the Register; the Register has continued to grow through two reorganizations, one in the 1970s and one in 1980s and in 1978 the NRHP was transferred away from the National Park Service, it was again transmitted to the NPS in 1981. In April 1966, six months before the National Register of Historic Places was created, the National Park Service's history research programs had been centralized into the office of Robert M. Utley, NPS chief historian, in Washington, D. C. as part of an overall plan dubbed "MISSION 66." On October 15, 1966, the Historic Preservation Act created the National Register of Historic Places and the corresponding State Historic Preservation Offices. The National Register consisted of those National Historic Landmarks designated before the Register's creation as well as any other historic sites within the National Park system.
The passage of the act, amended in 1980, represented the first time the United States had a broad based historic preservation policy. While the National Register did not provide specific protection to listed properties it did require federal agencies to assess the impact of activities on buildings and properties listed or eligible for listing on the NRHP; the 1966 act required those agencies to work in conjunction with the SHPO and an independent federal agency, the Advisory Council on Historic Preservation to confront adverse effects of federal activities on historic preservation. Another Interior agency, the National Park Service, had past experience overseeing the Historic American Buildings Survey and the Historic Sites Survey authorized in 1935; because of this, the fact that the Park Service was managing numerous historic properties within national parks, the NPS was the logical choice to head up the newly created historic preservation program. To encompass the newly created National Register of Historic Places, the National Park Service, under director George B.
Hartzog, Jr. created an administrative division called the Office of Archeology and Historic Preservation. The division oversaw several existing cultural resources programs, including the Historic Sites Survey, Utley's history division and the Historic American Buildings Survey, as well as the new NRHP and Historic Preservation Fund. Hartzog charged OAHP with creating the National Register program mandated by the 1966 law. Ernest Connally was the Office's first director and it was he who observed that American historic preservation ought be carried out, "with the informed advice and assistance of the professional and scholarly organizations of the disciplines most directly related to the endeavor. Within OAHP new divisions were created to deal with the National Register; the first official Keeper of the Register was an architectural historian. In the Register's earliest years, the late 1960s and early 1970s, organization was lax and SHPO were small and underfunded. Indeed, money was tight, but funds were still being supplied for the Historic Preservation Fund to provide matching grants-in-aid to listed property owners, first in house museums and institutional buildings but in commercial structures as well.
During this time period, the SHPO had little time to devote to serious planning if it wanted to. As a result, neither the State Historic Preservation Offices nor OAHP took planning seriously. In 1969 Connally told Charles Lee, a State Historic Preservation Officer from South Carolina, "write a paragraph of two on each of these headings. Call it'The Preliminary South Carolina Historic Preservation Plan.' If it makes any sense at all, I'll approve, you can file for your brick-and-mortar projects." In 1973 the NPS history programs affiliated with both the U. S. National Parks system and the National Register were formally categorized into two "Assistant Directorates." Established were the Assistant Directorate for Archeology and Historic Preservation and the Assistant Directorate for Park Historic Preservation. The Assistant Directorate for Archeology and Historic Preservation dealt with those cultural resources which were external to the National Parks system; the ADAHP included the Grants, National Register and Architectural Surveys and the Interagency Services Divisions of the Park Service.
The ADPHP, on the other hand, dealt with those resources associated internally with the NPS. The ADPHP included the History and Historic Architecture Division; until 1976 tax incentives were non-existent for buildings on the National Register. Before 1976 the federal tax code favored new construction over the reuse of existing, sometimes historical, structures. After 1976 the tax code was altered to provide tax incentives which promote preservation of income-producing historic properties; the responsibility of ensuring that only rehabilitations that preserved the historic character of a building would qualify for the federal tax incentives fell to the National Park Service. Properties and sites listed on the Register as well as those considered contributing properties to a local historic district "approved by the Park Service" became eligible for the federal tax benefits. Owners of properties listed on the National Register of Historic Places can be eligible for a 20% investment tax credit for the "certified rehabilitation of inc

Geographic 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 chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position. A common choice of coordinates is latitude and elevation. To specify a location on a plane requires a map projection; the invention of a geographic coordinate system is credited to Eratosthenes of Cyrene, who composed his now-lost Geography at the Library of Alexandria in the 3rd century BC. A century Hipparchus of Nicaea improved on this system by determining latitude from stellar measurements rather than solar altitude and determining longitude by timings of lunar eclipses, rather than dead reckoning. In the 1st or 2nd century, Marinus of Tyre compiled an extensive gazetteer and mathematically-plotted world map using coordinates measured east from a prime meridian at the westernmost known land, designated the Fortunate Isles, off the coast of western Africa around the Canary or Cape Verde Islands, measured north or south of the island of Rhodes off Asia Minor.
Ptolemy credited him with the full adoption of longitude and latitude, rather than measuring latitude in terms of the length of the midsummer day. Ptolemy's 2nd-century Geography used the same prime meridian but measured latitude from the Equator instead. After their work was translated into Arabic in the 9th century, Al-Khwārizmī's Book of the Description of the Earth corrected Marinus' and Ptolemy's errors regarding the length of the Mediterranean Sea, causing medieval Arabic cartography to use a prime meridian around 10° east of Ptolemy's line. Mathematical cartography resumed in Europe following Maximus Planudes' recovery of Ptolemy's text a little before 1300. In 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, England as the zero-reference line; the Dominican Republic voted against the motion, while Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911.
In order to be unambiguous about the direction of "vertical" and the "horizontal" surface above which they are measuring, map-makers choose a reference ellipsoid with a given origin and orientation that best fits their need for the area they are mapping. They choose the most appropriate mapping of the spherical coordinate system onto that ellipsoid, called a terrestrial reference system or geodetic datum. Datums may be global, meaning that they represent the whole Earth, or they may be local, meaning that they represent an ellipsoid best-fit to only a portion of the Earth. Points on the Earth's surface move relative to each other due to continental plate motion and diurnal Earth tidal movement caused by the Moon and the Sun; this daily movement can be as much as a metre. Continental movement can be up to 10 m in a century. A weather system high-pressure area can cause a sinking of 5 mm. Scandinavia is rising by 1 cm a year as a result of the melting of the ice sheets of the last ice age, but neighbouring Scotland is rising by only 0.2 cm.
These changes are insignificant if a local datum is used, but are statistically significant if a global datum is used. Examples of global datums include World Geodetic System, the default datum used for the Global Positioning System, the International Terrestrial Reference Frame, used for estimating continental drift and crustal deformation; the distance to Earth's center can be used both for deep positions and for positions in space. Local datums chosen by a national cartographical organisation include the North American Datum, the European ED50, the British OSGB36. Given a location, the datum provides the latitude ϕ and longitude λ. In the United Kingdom there are three common latitude and height systems in use. WGS 84 differs at Greenwich from the one used on published maps OSGB36 by 112 m; the military system ED50, used by NATO, differs from about 120 m to 180 m. The latitude and longitude on a map made against a local datum may not be the same as one obtained from a GPS receiver. Coordinates from the mapping system can sometimes be changed into another datum using a simple translation.
For example, to convert from ETRF89 to the Irish Grid add 49 metres to the east, subtract 23.4 metres from the north. More one datum is changed into any other datum using a process called Helmert transformations; this involves converting the spherical coordinates into Cartesian coordinates and applying a seven parameter transformation, converting back. In popular GIS software, data projected in latitude/longitude is represented as a Geographic Coordinate System. For example, data in latitude/longitude if the datum is the North American Datum of 1983 is denoted by'GCS North American 1983'; the "latitude" of a point on Earth's surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the Equator and to each other; the North Pole is 90° N. The 0° parallel of latitude is designated the Equator, the fun
