It also depends on the availability of a homogenized global glacier inventory. glaciers that meet at ice divides such as ice caps and icefields. It depends on how a glacier is defined and mapped and also requires differentiating between a glacier and a glacier complex, i.e. We identify the largest glaciers in two domains: on each of the seven geographical continents and in the 19 first-order glacier regions defined by the Global Terrestrial Network for Glaciers. Despite this long history, there is no authoritative answer to the popular question: ‘Which glaciers are the largest in the world?’ Here, we present the first systematic assessment of this question and identify the largest glaciers in the world – distinct from the two ice sheets in Greenland and Antarctica but including the glaciers on the Antarctic Peninsula. To properly import this into OSM would require newly vectorizing it which is especially difficult where there have been manual edits in the GLIMS data.Glacier monitoring has been internationally coordinated for more than 125 years. Some of the better data in GLIMS, notably that in northern Europe and Alaska, is hampered by poor vectorization of a raster data source. The following is by initial assessment (completeness is only a rough estimate) The quality of the data is strongly varying due to the different sources and analysis methods used. The shapefile also contains many duplicate polygons and the attributes seem partially broken. The full database dump is a huge shapefile containing ice and internal rock polygons separately.
