Data description:

 

(1) It is organized by each province in China; including urban only and urban and rural.

 

(2) The spatial resolution is 30m.

 

(3) The value in the map ranges from 0 to 34, indicating different years. Zero means non-urban, values greater than zeros indicate urban pixels.

 

Year and pixel value pairs are as following:

1978,1985,1986,1987,1988,1989,1990,1991,1992,1993,1994,1995,1996,1997,1998,1999,2000,2001,2002,2003,2004,2005,2006,2007,2008,2009,2010,2011,2012,2013,2014,2015,2016,2017
