Summary
| Description |
English: World map on the equirectangular projection (or plane chart or Plate Carree). The graticule spacing is 10 degrees. This is a low resolution figure, unsuitable for zoom. The figure was produced in Inkscape 1.47 with (public domain ) data from the NGDC World Coast Line (on WGS84 datum). The red line is a rhumb. The black line is a great circle. Neither are straight. The Tissot ellipses indicate distortion: they apply to any meridian. True scale on all meridians and equator. The triangle is used on the Wiki Mercator projection page. The base (on equator) and the vertical (on meridian) are true to scale but Pythagoras gives the incorrect distance on the hypotenuse. |

 | This SVG image contains embedded raster graphics.[1] Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics. Note: This template is only supposed to be used if the SVG file mixes vector and raster graphics. If the SVG file only contains raster graphics {{FakeSVG}} is supposed to be used. See also {{TopoSVG}}. |  |
