Abstract：

Based on the Google Earth Images in 2015 (2014-2016), the Global Multiple Scale Shorelines Dataset in 2015 was developed. The Google Earth Images includes those from DigitalGlobe，CNES/Airbus, some regions from Landsat and Copernicus. The shoreline here means that can be identified in remote sensing images to be sea water (or interactive area between sea and river waters) and land. The highest resolution and the most detail records of the global shorelines dataset is in meters resolution with the minimum area of 6 m². Based on this detail data records, the multiple scales of the data records in 30m, 250m and 1km were also developed according to the standard data abstraction procedures. The dataset is archived in latitude-longitude (no projection given) in both .kmz and .shp data formats. While the .shp format data is compressed for downloading (.raw). Normally, the data can be recognized from the data file name, for example: the file name SA_C_shoreline_m_gg_2015 means the data covers South American _ Continental _ shorelines _ meters resolution _ latitude and longitude _ in 2015. Coordinately, AF for African, OA for Oceania, NA for North American, EU for Europe, AS for Asia and AN for Antarctic. While the data name SA_I_shoreline_m_gg_2015 means the data covers South American _ Islands_ shorelines _ meters resolution _ latitude and longitude _ in 2015. （all data files following）Browse
