LCC NLCD 1992 Beta ALL
National Land Cover Database (1992 Beta) ALL
No raster values except those representing NODATA are excluded from the calculation of reporting unit effective area (i.e., effective area equals the total raster area within a reporting unit).
Coefficient values for impervious area calculations are based on those reported in Caraco et al. (1998). Those supplied for the nitrogen loading and phosphorous loading estimates were obtained from Reckhow et al. (1980). As coefficient values can vary considerably for a given land cover type across locations, all provided values should be evaluated critically before use and altered when necessary.
Information for the 1992 version of the NLCD has been archived, but for general information about the National Land Cover Dataset go to: http://www.mrlc.gov

<description>National Land Cover Database (1992 Beta) ALL Land Cover Classification Schema. Only viable for the NLCD dataset produced in 1992.

Coefficient values for impervious area calculations are based on those reported in Caraco et al. (1998). Those supplied for the nitrogen loading and phosphorous loading estimates were obtained from Reckhow et al. (1980).

* The classes node contains values from a land cover raster grouped into one or more classes.
* REQUIRED ATTRIBUTES
* Id - text, unique identifier, also used for automated generation of output field name
* - must conform to the field naming conventions dictated by the output database system
* OPTIONAL ATTRIBUTES
* Name - text, word or phrase describing class
* filter - text, a string of one or more tool name abbreviations separated by a ";"
* - possible abbreviations are: caem, flcp, flcv, lcosp, lcp, np, plcv, pm, rlcp, and splcp
* - used to exclude the class from the selectable classes in the tool's GUI
* xxxxField - text, overrides ATtILA-generated field name for output
* - where xxxx equals a tool name abbreviation
* - possible abbreviations are: caem, flcp, flcv, lcosp, lcp, rlcp, and splcp
* - a separate xxxxField attribute can exist for each tool
* - must conform to the field naming conventions dictated by the output database system
* A class can contain either values or classes but not both types.
* Value elements contain only an Id attribute which refers to a value in a raster.
* Values tagged as excluded="true" in the values node should not be included in any class.
