Does anyone know how to get LS-tool mentioned in Zhang et al 2013. https://www.researchgate.net/publication/256938578_Extension_of_a_GIS_procedure_for_calculating_the_RUSLE_equation_LS_factor
I tried using the Raster calculator in ArcMap 10.3.1 using the following formula by Bizuwerk et al., (2008).
LS = X/22.1m (0.065+0.045S+0.0065S^2
but I got only 0 value.
I found about LS tool after I researched on other ways to calculate slope length but can't find any place to access LS tool.
I would be really thankful if someone could help me find a way to either access LS tool or any other efficient and precise way to calculate slope length.
