U.S. Soils Data Added to World Water Online

By Lori Armstrong

The World Water Online (WWO) group in the ArcGIS Resource Center has 12 new web map applications based on the SSURGO soil survey database. These apps show soil characteristics that are useful for hydrologic modeling, such as drainage class, available water storage, water table depth, and ponding frequency. The hydrologic group code, which classifies soils based on infiltration rate, can be used to calculate curve number and model how much rain falling in an area will become runoff.

Juliet tells Romeo that a name is an artificial and meaningless convention.  Meaning what matters is what something is, not what it is called.  However in the geospatial community, a name is far from meaningless and what something is named is just as important as what something is.  Continue reading
