Early cartographers relied on astronomical observations

Position 1: This iterative process of correction and refinement laid the methodological foundation for modern geodetic cartography.

Position 2: These methods, while ingenious, introduced significant distortions, particularly in the representation of distant or unexplored regions.

Position 3: Gradually, the accumulation of empirical data allowed mapmakers to produce increasingly reliable projections of continental coastlines and interior territories.

Position 4: Early cartographers relied on astronomical observations and traveller accounts to construct maps of the known world.

Position 5: As maritime exploration expanded during the fifteenth and sixteenth centuries, navigators began correcting such inaccuracies through direct coastal surveying.
