HYDRO coverage


This coverage represents land, fresh water and marine water within the mapped area.


The hydro coverage contains those water bodies that were found on the original soil survey map.


The hydro coverage is used as a mask to shade areas of the soil polygons which consist of fresh water or ocean. The TYPE field in the hydro coverage PAT identifies each polygon, where:

  • L = Land
  • O = Ocean
  • W = Fresh Water

This coverage is used in a manner equivalent to the  HYDRO coverage available for the SLC product.  For exact instructions on how to use of this coverage, see How to map SLC data
