31. I established on the Talk page that map projections are a cartographic endeavor with its own literature. 32. :Images of map projections are invaluable encyclopedically. 33. More formally, such coordinates can be obtained from three-dimensional coordinates using the artifice of a map projection . 34. The evaluation of the meridian distance integral is central to many studies in geodesy and map projection . 35. The mathematics of projection do not permit any particular map projection to be " best " for everything. 36. This is a standard technique of extending the region over which a map projection has a given accuracy. 37. This is a more difficult problem to fix, and what makes this like the spherical map projection problem. 38. :Now, I agree with Strebe that the page should focus on the typical map projections which he advocates. 39. As on all map projections , shapes or sizes are distortions of the true layout of the Earth's surface. 40. The choice between the two map projections is based on the shape of the state and its zones.
