Due to climate warming and complex glacier dynamics, glaciers in Svalbard are melting rapidly, and it is necessary to regularly update glacier boundaries to obtain dynamic change information to provide basic data support for sea level rise projections. Therefore, using a series of Landsat images as the main data source and a semi-automated glacier mapping method, we have produced glacier inventories for three periods (SGI-1990s, SIG-2000s, and SGI-2020s) in Svalbard with an overall data accuracy of ±1.29%.
A series of Landsat images: including Landsat 5 TM, Landsat 7 ETM+, Landsat 8 OLI; spatial resolution is 30m. Obtain address: https://earthexplorer.usgs.gov/
Two methods were used to evaluate the accuracy of the datasets. The results of repeated manual digitization based on higher-resolution images such as Sentinel-2 showed that the glacier cataloging accuracy in different periods was ±0.43%, ±0.77%, and ±1.33%, respectively. The accuracy assessment results based on the buffer were ±1.25%, ±1.29%, and ±1.28%, respectively.
