Mississippi (Hydrologic Regions 05, 06, 07, 08, 10, 11)

The Mississippi drainage area is composed of hydrologic regions 05, 06, 07, 08, 10, and 11.

For ESRI Grids the Mississippi is divided into production units: 05 a to c, 06 a, 07 a to c, 08 a and b, 10 a to h, and 11 a to e.

NHDPlus Shapefile and DBF components are distributed by hydrologic region.

NHDPlus ESRI Grid components are distributed by production units.

*An ESRI Grid is a proprietary format for a raster dataset that defines space as an array of equally sized cells arranged in rows and columns.  Each cell contains an attribute value and location coordinates. Unlike a vector structure, which stores coordinates explicitly, raster coordinates are contained in the ordering of the matrix. Groups of cells that share the same value represent the same type of geographic feature.

**A Shapefile is a published, but proprietary, data format from the Environmental Systems Research Institute, Inc. (ESRI).

***Zip is a common type of file compression.
