The Global Artificial Land Surface in 30 meters resolution (GlobeLand30-ATS2010 for short) was developed based on the data mining methodology by integrating and analyzing the 9907 scenes of the USA Landsat TM5, ETM data and 2640 scenes of the China environment disaster mitigation satellite (HJ-1) data in 2010(?1). Since the Artificial Land Surface is mostly a mosaic of, for example, buildings, trees, roads, small-water bodies, and grasslands that are frequently combined, it makes data mining for identifying the artificial land surface more difficult. The Pixel-Object-Knowledge (POK)methodology was applied in this study and data development. The 30m dataset shows where and how many residents there are in cities and villages, as well as industrial lands, airports, and roads worldwide. The total area of the global artificial land surface is 1.1875 million km2, which is 0.88% of the total land surface of the world. The global data were organized into 750 tiles, according to the 5? (latitude) x 6? (longitude) within the region from 60?S to 60?N (674 tiles), and 5? (latitude) x 12? (longitude) within the region from 60? N to 80?N (76 tiles) (the Antarctic continent is not included). The data tiles are combined into 5 compressed data groups (Asia, Europe, North America, South America, and Africa and Oceanic Countries), Four different data files comprise each of these data groups, they are: (1) land-surface water data (raster data with GeoTIFF format); (2) coordinate information data (TIFF WORD format); (3) areas of selected remote sensing data (.shp format); and (4) a metadata file (XML format). In addition, the 750 data file list, including the file names, corresponding geographic coordinates, and zoning codes are listed at the file. The dataset is one of the layers of the Global Land Cover Dataset in 30m Resolution in 2010 (GlobeLand30_2010), which were donated to the United Nations by China in September 2014.
