Significant Islands of Britain – GPX files & Bagging list
With the latest data from DoBIH www.haroldstreet.org.uk now hosts GPX files & Bagging list for the Significant Islands of Britain (SIBs)
SIBs are defined as naturally occuring land which at MHWS is completely surrounded by water with either an area of at least 10 hectares within the MHWS contour line or a prominence of at least 30 metres above MSL, or both, all man-made links and structures being discounted. They were researched by Alan Holmes.
The DoBIH data gives the Main SIBs, which comprise all islands having an area of at least 30 hectares or a drop of at least 30 metres, excluding sea stacks, as we believe this category is of most interest to baggers.
