AB  - Multi-temporal glacier inventories provide key information about the glaciers, their characteristics and changes and are inevitable for glacier modelling and investigating geodetic mass changes. However, to date, no consistent multi-tempo glacier inventory for the whole of the Karakoram exists, negatively affecting the monitoring of spatiotemporal variations of glaciers’ geometric parameters and their related applications. We used a semi-automatic method by combining automatic segmentation and manual correction and produced multi-temporal Karakoram glacier inventories (KGI) for 1990s, 2000s, 2010s, and 2020s, compiled from Landsat TM/ETM+/OLI images. Our assessments using independent multiple digitization of 37 glaciers show that the KGI is sufficiently accurate, with an overall uncertainty of ±3.68%. We attached more than 20 attributes for each analyzed glacier, including glacier ID, area, topographical information and surface types. The data are provided as ESRI Shapefile files with detailed attributes. The KGI data in this study can provide basic glacier outlines for GLIMS and the forthcoming planned release of the next versions of the RGI, as well as for other glacier-related research applications.
