But if you are doing a problem with either spherical symmetry going out the same distance in the x y and z directions is the same or cylindrical symmetry this means symmetry about one axis using different coordinate systems may make the problem easi Dr. Midori Kitagawa. Coordinate Systems. Coordinates are an . ordered. set of values which specify a location relative to some origin. . The . order. of coordinates is important.. There . are a variety of coordinate systems.. Hugh Mackenzie. April 2014. Summary. What are the household projections?. How are they produced?. Five inputs. Seven steps. Variant projections. How to get Census data & analysis. What are household projections?. Geodesy. - the shape of the earth and definition of earth datums. Map Projection. - the transformation of a curved earth to a flat map. Coordinate systems. - (x,y,z) coordinate systems for map data. Reflections on the Coordinate Plane. The undisturbed surface of a pond acts like a mirror and can provide the subject for beautiful photographs. Reflections on the Coordinate Plane. We call the waterline a “line of symmetry” because if the photo were folded at the waterline, the two halves would form a mirror image of each other. Datums. and Map . Projections. D’Arcangelis. 11/9/09. Every map user and maker should have a basic understanding of projections, no matter how much computers seem to have automated the process.. Hmmm…. COORDINATE SYSTEMS. .
