Global Artificial Land Surface (GLC-30m)
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.

You can customize the template to suit your needs. You can add
and remove fields and fill out default information (e.g. contact details).
Fields you can not change in the default view may be accessible in the more
comprehensive (and more complex) advanced view. You can even use the XML editor
to create custom structures, but they have to be validated by the system, so
know what you do :-)
