Glacier outlines Nordland 1900

ArcGIS geodatabase containing Glacier Area Outlines (GAO) of all glaciers (n = 1587) in the northern Norwegian county of Nordland, including a small number of glaciers in the adjacent counties, in ca. 1900 (1882-1916). Glacier outlines were digitised from georectified historical gradteigskart maps, published by Norges geografiske oppmaling (NGO; Norwegian Geographical Survey; now: Kartverket – Norwegian Mapping Authority). These maps are based on field surveys carried out between 1882 and 1916. The data set and the uncertainties associated with it are described in detail in Weber et al. (2020; Journal of Glaciology).
