The image is sent back to the web browser through a CGI program. In addition, the Internet Map Server extension for ArcView is used to show the different layers for the study area. The information includes soils, DEM, streams, roads, contours, slope, flow length, and calculated LS factor. A user can look at the study area for those information by simply selecting a layer. From this web site, a user can do a wide range of scenario predictions for soil erosion.
Data is available for most counties in Michigan.
Terrain information inquiry and erosion index mapping is also available for the study area. This web site can be used for what-if scenario prediction and sensitivity analysis. The results are obtained from the web site with same area, crop rotation and tillage management. 10.93 13.8 Table 2. 1.62 1.62 1.71 Table 1-2 show that soil erosion is more sensitive to the slope steepness than to slopelength.
