Methodological aspects

The territorial boundary was measured using cartographic digitalisation to a scale of 1/50,000, which corresponds to a division into segments of 15 metres. The total is offered in kilometres. The measurement of the maritime boundaries includes the contours of quays, wharfs and other constructions that due to their size have been digitalised; however, islands are excluded. The border with France includes the boundaries of the municipality of Llívia.
