Topographic factor| LS factor| Slope length and Steepness factor

Hello everyone, This video is for LS factor Calculation. The LS factor, which is crucial for understanding soil erosion (RUSLE and MUSLE model). This tool we're featuring calculates the L (slope length) and S (slope steepness) factors separately, without any gaps or sinks in the file, a key improvement over common errors encountered in QGIS. The LS factor, which represents the rate of soil loss under specific conditions, is derived from the slope length (L) and slope steepness (S), as outlined in studies by Das et al. (2018) and Swarnkar et al. (2018). We use a 90-meter spatial resolution DEM to accurately calculate the LS factor. The tool was initially developed using Arc Macro Language (Hickey 2001), and later optimized in C++ (Van et al. 2004) to enhance its functionality. The DEM input data is converted into ASCII format for compatibility, and the calculation follows the Wischmeier and Smith (1978) equation, ensuring precise results for land surface analysis. #GeospatialAnalysis #LSFactor #SoilErosion #SlopeLength #SlopeSteepness #DEM #GIS #QGIS #ArcMacroLanguage #Cplusplus #ShuttleRadarTopographicMission #WischmeierAndSmith #SoilLoss #DigitalElevationModel #LandSurfaceAnalysis #ErosionPrediction #Tutorial #GISAnalysis #GeospatialTools #scienceandtechnology
