The rod, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units , it is defined as 16 + 1 ⁄ 2 feet , equal to exactly 1 ⁄ 320 of a mile , or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain ), and is exactly 5.0292 meters.
Also narrow. A land or water passage that is confined or restricted by its narrow breadth, often a strait or a water gap. nation A stable community of people formed on the basis of a common geographic territory, language, economy, ethnicity, or psychological make-up as manifested in a common culture. national mapping agency A governmental agency which manages, produces, and publishes ...
In this example, the immediate surroundings include a pavement, parking area, and section of the road out in front and a section of an alley at the back. Plot structures include a house, private walkways, and at the back - a detached garage with a drive access to the alley and a small area for refuse.
The existence of section lines made property descriptions far more straightforward than the old metes and bounds system. The establishment of standard east-west and north-south lines ("township" and "range lines") meant that deeds could be written without regard to temporary terrain features such as trees, piles of rocks, fences, and the like, and be worded in the style such as "Lying and ...
Position resection and intersection are methods for determining an unknown geographic position (position finding) by measuring angles with respect to known positions.In resection, the one point with unknown coordinates is occupied and sightings are taken to the known points; in intersection, the two points with known coordinates are occupied and sightings are taken to the unknown point.
The World Geographic Reference System (GEOREF) is a geocode, a grid-based method of specifying locations on the surface of the Earth.GEOREF is essentially based on the geographic system of latitude and longitude, but using a simpler and more flexible notation.
The maturation of complex analysis led to general techniques for conformal mapping, where points of a flat surface are handled as numbers on the complex plane.While working at the United States Coast and Geodetic Survey, the American philosopher Charles Sanders Peirce published his projection in 1879, [2] having been inspired by H. A. Schwarz's 1869 conformal transformation of a circle onto a ...
Surveying: surveyors use absolute locations to make maps and determine property boundaries. Tectonics : GPS enables direct fault motion measurement of earthquakes . Between earthquakes GPS can be used to measure crustal motion and deformation [ 132 ] to estimate seismic strain buildup for creating seismic hazard maps.
