built-up and bare land in urban areas, such as the Normalised Difference Built-Up Index (NDBI) [7], Index-based Built-Up Index (IBI) [1], Urban Index (UI) [8], Normalised Difference Bareness Index (NDBaI) [4], and Bare soil index (BI) [9], have been employed in various ...
The following formula [61] describes the fractional vegetation cover to indicate vegetation growth in each area: FVC=NDVI−NDVISoil NDVIVeg− NDVISoil ,FVC=NDVI−NDVISoil NDVIVeg− NDVISoil , (1) where NDVISoil is the NDVI value of the pure soil image element; NDVIVeg and Total are...
Compared to the bareland, the ingredient of soil is the same as the landslide; however, most of them are located in the flat area. Thus, the reflection on hyper-spectrum image data must be different to a landslide. This is the objective to classify them by applying the similarity of a ...
