Abstract & Keywords
Abstract: Impervious surface is one of the most basic components of a city which has a significant impact on urban ecological environment and regional development. Remote sensing has been widely used in impervious surface research in recent years due to its fast, large-scale, multi-scale and reproducible ground observation advantages. Taking Sanya city as the research area, this study selected and collected the Landsat series remote sensing image data of 2004, 2008, 2011, 2013 and 2015 in this area. A method combining BCI index and BI index is proposed to extract the impervious surface information in the study area. Based on this method, the impervious surface distribution maps of the five phases of Sanya City in 2004, 2008, 2011, 2013 and 2015 were obtained. Precision verification using Google Earth images which have high accuracy. It was concluded that this method is operability, simple and easy operation, the overall accuracy is higher than 80%, and the Kappa coefficient is above 0.80. This dataset can provide reference for the rational planning of “sponge city” in Hainan Province or other provinces and cities.
