It has been argued that the errors in the trade route direction compared with the compass bearing directions marked along the routes (see Chinese characters marked next to the black line in Fig. 10) indicated lack of knowledge of a particular part of the world or problems in cartography such as methods to project a spherical earth onto a planar map.
The trade route directions were drawn accurately according to their compass needle directions when they were through the open sea or when they were drawn before the coastlines were laid down.
These trade route directions were all accurately drawn, on the other hand, those trade routes that had to fit the coastline tend to be drawn off course compared with the compass directions marked (Fig. 12).
An analysis of the trade route directions in comparison to the compass bearings marked next to them, shows that most of the route were drawn within the margin of error (7.5°) determined above (Fig. 12).
