This protocol outlines the method for deriving gradient values from Geographic Information Systems (GIS) data. The process involves utilizing digital elevation models (DEMs) to calculate slope and aspect, providing essential information for terrain analysis. By following this protocol, users can accurately extract gradients that are critical for applications in hydrology, environmental studies, and urban planning. The steps include data preparation, analysis tools in GIS software, and interpretation of results for practical use.
