This paper proposes the most simplified, concise and accurate geostatistical method for the spatial representation of the surface sediment distribution. The methodology uses conditional strings in the raster calculator of Map Algebra using ArcGIS 10.x for preparing sediment distribution maps. This methodology is an updated version of USGS Arc Map Sediment Classification since the latter is a customized toolbar for Arc GIS 9.X. The conditional strings are derived from the ternary classification systems of Folk and Shepard. These strings are further updated for mapping hard bottom along with sediment types. For generating sediment distribution map in an area with natural or artificial barriers using conditional strings in ArcGIS 10.x is also discussed here. The ‘SedTypes’ free... view more»
