- Abstract:
-
Rainfall erosivity is one of the essential factors in soil erosion models. Collection and processing of rainfall data are usually time-consuming. These data are generally stored in text format, which causes a common issue on data missing. This study developed a rainfall erosivity calculator by integrating the daily, half-monthly, monthly and yearly rainfall erosivity calculation models with ArcGIS Engine and.NET platform. Moreover, various spatial interpolation methods were implemented in this calculator in order to generate different interpolation results based on the collected rainfall data. The results demonstrate that this developed calculator is able to manage rainfall data quickly and effectively. Different interpolation methods can be employed to generate raster data for the spatial distribution of rainfall erosivity. These raster data can be masked or resampled individually or in batch by request. Statistics and thematic mapping of the rainfall erosivity can also be conducted by using this calculator, which provides the application basis for the visualization and storage of results.
