Summary
| Description |
English: The world on an equal-difference latitude polyconic projection, with a 10° graticule and Tissot's ellipses overlaid. Each red circle is 1 000 km in diameter. Coastline data from www.naturalearthdata.com. Colors inspired by Eric Gaba. This map was generated using the code at github.com/jkunimune/Map-Projections, based on the reference points and forumlas published by Yè Yuǎnzhì in the article "栅格数据的等差分纬线多圆锥投影转换 (The transformation of equivalent difference parallel polyconic projection on raster data)" in 测绘通报 (Topography Communications), 2012, issue 9, page 68; article number 0494-0911(2012)09-0068-03. |
