The remote sensing big data formed by these continuously emerging massive remote sensing data provides abundant data support for Earth science research. Global scale historical remote sensing data has been accumulated for more than half a century. The impervious surface data can be freely downloaded from. The 40-year continuous and consistent impervious surface distribution data in China would generate widespread interests in the research and policy-making community. Our results indicate that the growth of impervious surface in China was not only fast but also considerably exceeding the per capita impervious surface area in developed countries like Japan. Overall accuracies reached more than 90%. The 1978 data were at 60-m resolution, while the 1985–2017 data were in 30-m resolution. With available data in GEE, we were able to map impervious surfaces over the entire country circa 1978, and during 1985–2017 at an annual frequency.

In this paper, we made use of reliable impervious surface mapping algorithms that we published before and the Google Earth Engine (GEE) platform to address this data gap. However, annual maps of impervious areas in China with high spatial details do not exist during this period. Over the past 40 years, impervious surface areas in China have grown rapidly. Timely, accurate, and frequent information on impervious surfaces is critical in both social-economic and natural environment applications. Google Earth explore not only Earth, view to Sky, Mars and Moon.Impervious surfaces are the most significant feature of human settlements.
