Paper Abstract
There is an increasing need to understand pattern and growth of impervious surfaces in rural regions. However,
studies using remote sensing of impervious surfaces have often focused on mapping impervious surfaces in urban
regions with less emphasis placed on the rural impervious surfaces. In this paper, we proposed a new index, Rural
Impervious Surface Index (RISI) by taking advantage of narrow spectral bands of Landsat 8 OLI for estimating
impervious surfaces within rural land covers. This index is based on the combination of Normalized Difference Built-up
Index (NDBI), Soil Adjusted Vegetation Index (SAVI) and Soil Index (SI). Respectively, these represent the three major
rural land covers components: impervious surfaces, vegetation, and soil. The index was further used for estimating
fraction of impervious surfaces using fuzzy KNN classifier. The performance of this technique was also compared with
Linear Spectral Mixture Analysis (LSMA). Our results showed that RISI could accurately detect spatial pattern of rural
impervious surfaces due to the suppressing background noise and minimizing spectral confusion. Accuracy assessment
revealed that incorporation of RISI with fuzzy KNN classification generates higher correlation coefficient, lower root
mean square and systematic error compared to the LSMA technique.
