PPT-Conversion from Latitude/Longitude to Cartesian Coordinates

Geodetic  Datums Define the shape and size of the earth Reference points on a coordinate system used to map the earth There are hundreds of datums currently in use all are either vertical or horizontal in orientation . Geodetic . Datums. Define the shape and size of the earth. . Reference points on a coordinate system used to map the earth. . . There are hundreds of . datums. currently in use; all are either vertical or horizontal in orientation. . Part I: Polar Coordinates. Objectives. Objectives: Know how to convert between polar and Cartesian coordinates and how to sketch functions in polar coordinates. Corresponding Sections in Simmons 16.1,16.2,16.3. Latitude. Distance measure in degrees- from 0. o. to 90. o. North or South of the equator. Equator- . primary reference point. Lines . are called parallels- form complete circles around the earth; are parallel to the . 2.2 trig ratios with obtuse angles. Trig ratios with obtuse angles. “OBTUSE”. : Greater than 90. o. , less than 180. o. Similarly, coordinates on a . Cartesian Plane. are used to determine a location on a plane relative to the origin. History. Use of grid lines . originated from. about 300 B.C.E by Greek . astronomers . Hipparcus. and . Ptolemy. Used spherical trigonometry observations using sun, moon, and stars to plot points on a spherical earth. 2. Grid System. Lines of latitude and longitude cover the entire Earth, allowing us to find any location.. The . cardinal directions. are North, South, East and West.. Lines of Latitude run East to West. Globe Skill Review. What is the invisible line at 0. ° latitude called?. The equator is the invisible line at . 0. ° latitude.. The equator is the “belt” of the earth.. What kind of lines show how far a place is away from the equator?. Hemispheres. A place can be either in the NORTHERN or SOUTHERN hemisphere. That means it is in one of the halves above or below the imaginary east-west line known as the EQUATOR.. A place can also be in either the WESTERN or EASTERN hemisphere. That means it is in one of the halves on either side of the imaginary north-south line known as the PRIME MERIDIAN.. Do Now. : Why do you think we call the equator the equator?. HW: Latitude/Longitude practice . ws. . . 4 Hemispheres. The equator splits apart the Northern and Southern Hemisphere. The Prime Meridian and International Date Line split the Eastern and Western.
