From: Study of slope length (L) extraction based on slope streamline and the comparison of method results
Spatial relative difference coefficients calculated by different slope length calculation methods. (a)–(c) the spatial relative difference coefficients generated by the SLzh method as the base algorithm and the SLlaya, SLfu and SSM method as the comparison algorithms in turn. (d)–(f) The spatial relative difference coefficient maps generated by the SLlaya method as the benchmark algorithm and the SLzh and SLfu methods and the SSM as the comparison algorithms, respectively. (g)–(i) The spatial relative difference coefficient maps generated by the SLfu method as the benchmark algorithm and the SLzh, SLlaya and SSM methods as the comparison algorithms, respectively. (j)–(m) The spatial relative difference coefficient maps generated by the SSM as the benchmark algorithm and SLzh, SLlaya, and SLfu methods as the comparison algorithms, respectively.
