Resumen
A cartographic examination of the hydrographic network in the mapping of Portugal by Fernando Álvaro Seco demonstrates, on one hand, its high quality in general and allows us, on the other hand, to seek reasons for the mistakes in its drawing and orienting, as well as omissions made. To this effect, the plotting of the rivers was compared with descriptions of that same period and an examination was also made of the distribution of bridges and hydronymy. A solid spatial correlation was found to exist between the quality of the plotting and the density and frequency of the various itineraries, along with the influence of military concerns for the Eastern radius of the Portuguese kingdom. The correlation with the properties of relief and regional climate is important but less direct.
The cartographer who conceived the map undertook complex work of compilation and harmonisation of documents of several origins, probably dating much further back than to when the map was offered to Rome in 1560
