Lecture 3 Geodesy Projections Pdf Latitude Geography This document discusses coordinate systems and map projections. it defines spatial references, coordinate systems including geographic, projected, local and vertical systems. Map projection the transformation of a curved earth to a flat map. coordinate systems (x,y,z) coordinate systems for map data.
Lecture 6 Geodesy And Coordinate Systems Pdf Geodesy Latitude Standard lines and points a line(s) or point on a map that has the same scale (dimensions) as the reference globe. * a 'geographic' coordinate system has a measurement framework with coordinates that measure angles from the earth's center. * a 'projected' coordinate system is one where the measurement framework represents a conversion of the spherical location to a 'planimetric' (flat) location. • projected coordinate systems use mathematical equations (the map projection) to transform latitude and longitude coordinates into coordinates for a flat map. • video: all maps are wrong. i cut open a globe to show why. vox. To effectively use gis, we must develop a clear understanding of how coordinate systems are established for the earth, how these coordinates are measured on the earth’s curving surface, and how these coordinates are transferred to flat maps.

Study with quizlet and memorize flashcards containing terms like geodesy, map projection, coordinate systems and more. Simply put, a datum is the mathematical model of the earth we use to calculate the coordinates on any map, chart, or survey system. all coordinates reference some particular set of numbers (datum) for the size and shape of the earth. The easiest way to try to transfer the information onto a flat surface is to convert the geographic coordinates into an x and y coordinate system, where x is longitude and y is latitude. Geodesy, map projections and coordinate systems • 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.
