International Association of Geodesy (IAG). It used what could be called the global positioning system of the day - geodetic astronomy - to establish the datum origin and orientation As much as the technology of the day allowed‚ it was an effective implementation of an internationally accepted terrestrial reference system. Although we now know the difference between the centre of the BT68 ellipsoid and the centre of mass of the earth‚ until the advent of satellite geodesy in the 1960’s and 1970’s‚

The graticule‚ the mesh formed by the lines of constant latitude and constant longitude‚ is constructed by reference to the rotation axis of the Earth. The primary reference points are the poles where the axis of rotation of the Earth intersects the reference surface. Planes which contain the rotation axis intersect the surface in the meridians and the angle between any one meridian plane and that through Greenwich (the Prime Meridian) defines the longitude: meridians are lines of constant longitude

Courtney Hines Ms. Chapline ITSC 1309 17 June 2011 Can You Find Me Now? How is a Nintendo Wii game console able to determine the location of a Wii Remote while a player interacts with a game? The answer is Triangulation‚ a process that determines the location of an object by measuring the angles from two of more fixed points. Surveyors often use triangulation to measure distance. Starting at a known location and elevation‚ surveyors measure a length to create a base line and then use a theodolite

Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

Brief descriptions of GPS & GIS Name: Fatima Aba-alkhail GPS: The Global Position System (GPS) was developed by the United States ’ Department of Defense; determine data on the surface of the earth by satellites using longitude and latitude coordinates and height‚ which operate 24 hours a day‚ in all types of weather. There are three types of segments for this system which are: space segment‚ control segment and user segment. Examples: 1- GPS help to forest fire place determination. 2-

Cartesian Coordinate System -A Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates‚ which are the signed distances from the point to two fixed perpendicular directed lines‚ measured in the same unit of length. Cartesian coordinate system is a way of locating objects in either two- or three-dimensional space by specifying their X(horizontal) position‚ Y (vertical) position and Z (through) position. It is used in graphics and in positioning text
