Lecture 3 Geodesy Projections Pdf Latitude Geography The graticule is the gridded network of latitude and longitude, the pattern that the meridians of longitude and the parallels of latitude form on the surface of the earth. Ge 103 lecture 3 free download as pdf file (.pdf), text file (.txt) or view presentation slides online. this document discusses coordinate systems and map projections.
Geometric Geodesy Part Ii Pdf Pdf Geodesy Latitude This chapter introduces geodesy, the science of measuring the shape of the earth, and map projections, the transformation of coordinate locations from the earth’s curved surface onto flat maps. Geodetic coordinate system the location of a point. for example, a 1 d coordinate system is needed to identify the height of a point above the sea surface. e, the orientation of the axes, and the origin. in the case of a 3 d geodetic (also known as geographic) coordinate system, the re. Projections distort distance, area, direction and shape to greater or lesser degrees; choose projection that minimizes the distortion of the map theme. points of tangency, standard parallels and secants are points or lines of no distortion. This chapter intro duces geodesy, the science of measuring the shape of the earth, and map projections, the transformation of coordinate locations from the curved earth surface onto flat maps. defining coordinates for the earth’s surface is complicated by two main factors.
Lecture 3 Concept Of Geographic Coordinate Systems Map Projections And Projections distort distance, area, direction and shape to greater or lesser degrees; choose projection that minimizes the distortion of the map theme. points of tangency, standard parallels and secants are points or lines of no distortion. This chapter intro duces geodesy, the science of measuring the shape of the earth, and map projections, the transformation of coordinate locations from the curved earth surface onto flat maps. defining coordinates for the earth’s surface is complicated by two main factors. Ce 559 lecture 3 this document discusses key concepts in geographic information systems including earth shape models, map projections, coordinate systems, datums, and common projections used like mercator, transverse mercator, albers equal area conic, and lambert conformal conic. Topic 4: geodesy and map projections chapter 2: chang chapters 2 & 3: dent et al. Summary continued projected coordinate systems are built on a map projection. these are specific grids that may be used to define specific geographic location on the earth’s surface. it is important to be aware that there are many different ways to determine a geographic location!. Explore geodesy and map projection with lecture 3 focusing on coordinate systems. learn about latitude, longitude, and conversions between geographical coordinate formats.
