Hello, in order to apply the USLE equation, I need to calculate the factor C, please how can I use NDVI to calculate this factor?
Best regards

If you use Arc GIS, I can give you a set of the equation on rater calculator
NDVI can be used, but, keep in mind that the NDVI must be related with field measurements, to predict the amount of vegetation. NDVI is just a number...
after calculation you need to calculate the area of each class of ndvi in case you use slicing way
You need to classify first values of NDVI into classes. After that you use statistic spatial in order to estimate the surface occupation of each class.
Use tool GISUS !
easy to use in ArcGIS.
or use formula in raster calculator
hello
you can use the relation of Van der Knijff et al. (2000)
or Ma et al. (2001)
or Li et al. (2014)
tool names GISUS is easy to use
