| Creating a Geographic Coordinate System: Select a specific geodetic datum the result of attaching a "free-floating" reference ellipsoid an ellipsoid that is drawn to best-fit an area. World reference ellipsoids are drawn to best-fit the entire geoid; local ellipsoids are best fit on one side to a single place of the geoid to a specifically measured geoid a model of the variation between global mean (average) sea level and local mean sea level the measurement above or below the global average at a single point A GIS vector data in any sort of digital science or art, is simply denoting a type of graphical representation using straight lines to construct the outlines of objects geometry type which is made up of just one vertex pl. vertices One of a set of ordered x,y coordinate pairs that defines the shape of a line or polygon feature. , marking a single XY location in any given geographic or projected coordinate system. on the Earth's surface used for recording the elevation of topographic surface a detailed map of the surface features of land. It includes the mountains, hills, creeks, and other bumps and lumps on a particular hunk of earth. The word is a Greek-rooted combo of topos meaning "place" and graphein "to write." 's relief the difference between the highest and lowest point within a particular area while landforms are the descriptive words for individual features , which is used to measure precise elevations on the topographic surface a detailed map of the surface features of land. It includes the mountains, hills, creeks, and other bumps and lumps on a particular hunk of earth. The word is a Greek-rooted combo of topos meaning "place" and graphein "to write." via control points and benchmarks. (attaching a reference ellipsoid an ellipsoid that is drawn to best-fit an area.

East-west lines have a very obvious start point: the equator. North-south lines must start somewhere, so when it is established for a particular geographic grid, it can be considered the principal meridian. (a labeled grid combining an Earth-Centered, Earth-Fixed coordinate system (a principle meridian and an angular unit of measure the selected units for measuring angles. Choices include degree and radians. ) and an affine transformation). The output is an a means to locate and label specific locations on the Earth’s surface. Once these places are labeled, tools such as GPS units can lead you right to them. The term Geographic Coordinate System is often incorrectly used interchangeably with datum. While they seem similar, a geographic coordinate system is the whole package: a geographic grid the result of using an established angular unit of measure to label the intersections of north-south and east-west lines on the surface of the Earth starting the labels at a principal meridian the north-south line from which the labeling begins. East-west lines have a very obvious start point: the equator. North-south lines must start somewhere, so when it is established for a particular geographic grid, it can be considered the principal meridian. and a datum, while a datum is just the part which links a reference ellipsoid an ellipsoid that is drawn to best-fit an area.
