After the frequency ratio raster maps of all the landslide factors are prepared, the next step is to add these raster maps based on the mathematical combination theory.
Where FR 1, FR 2, FR 3 … FRn are the frequency ratio raster maps of landslide causal factors.
In this study, the raster maps of the frequency ratio values for the eight landslide factors were extracted with landslide and non-landslide points.
The frequency ratio raster maps of landslide causal factors with landslide and non-landslide points was extracted using ArcGIS tool and saved into dbf format.
FR = Frequency ratio raster map for li = lithology, dl = distance from lineament, dr = distance from river, lu = land use, sl = slope, as = aspect, pr = profile curvature and pl = plan curvature.
Until now researchers, who were engaged in the this model, were simply summing all the frequency ratio raster maps of landslide factors (Lee and Sambath 2006) or exclude one factor and sum all the remaining ones (Lee and Talib 2005).
Population weighted raster maps showed the frequency of abuse against women of different types (for example, Figures 1 and 2).
Top: PSTHs, corresponding to the raster plots, indicate calcium event frequency at each time point.
In DFM, the cantilever is oscillated at a given frequency as it raster-scans over the surface and touches the sample only at the end of its downward movement, resulting in amplitude reductions at positions of elevated objects.
The site responded most strongly to either a low frequency sound (Fig. 3A, top raster) or a high frequency sound (Fig. 3A, middle raster) at the RF center (azimuth = 0°).
