I am trying to perform a RUSLE analysis and cannot figure out how to calculate the LS factor. I have been to http://www.onlinegeographer.com/slope/slope.html and tried to use the AML code but cannot get it to work. I have also tried the C++ program and my watershed is too large for it to run. Does anyone know how to get the AML code to work on ArcMAP 9.3?
When trying to run the raster calculator equation I keep getting ERROR 010328: Syntax error at or near symbol SPACE, and ERROR 010267: Syntax error in parsing grid expression. Do you know how to correct these?
