Depending on the extent and the distortion property of the map, the application returns a list of proposed map projections with additional projection parameters if necessary. There are PROJ and WKT links next to each projection that open a popup window with a PROJ or Well-Known Text string available for copying to the clipboard. Both strings are used in many cartographic and GIS applications. Projection Wizard displays a map preview on the right side of the list with a suggested projection. The preview shows how the projected data will look using D3... In some rare cases, it is useful to retain scale along great circles in regional and large-scale maps. Map readers can make precise measurements along these lines that retain scale. It is important to remember that no projection is able to correctly display all distances and that only some distances are retained correctly by..
