Ptolemy integrated the previous research results, thought that maps should be drawn according to fixed points with known latitude and longitude, and put forward the concept of drawing latitude and longitude network on maps. To this end, Ptolemy measured the latitude and longitude of important cities and strongholds in the Mediterranean and compiled eight volumes of geographical works. Including the latitude and longitude of 8000 places. In order to draw the longitude and latitude lines on the earth on a plane, he tried to draw them into simple sectors, thus drawing the famous Ptolemy map. /kloc-At the beginning of the 5th century, the navigator Henry began to put "Ptolemy Map" into practice. However, after repeated inspection, I found that this map is not practical. Some of Henry's captains said with regret, "Although we admire the famous Ptolemy very much, we found that the fact is contrary to what he said." for reference only
