APPENDIX A:

 

The Anderson Classification System:

 

The Anderson et al. 1976 classification system is a hierarchical system based on four digits. The four digits represent one to four levels of classification: Level I, general, Level II descriptive, Level III, detailed, and Level IV, most detailed. Therefore the first digit in the code is the Level I general classification. The first two digits reveal the Level II descriptive code, the first three digits a more detailed description, while all four digits represent the most detailed level of classification. The layer is generally a Level II - III classification but some level IV detail is included.

 

For example the code 4311 represents:

 

            4---                   Forestland

            43--                   Forestland, Mixed Deciduous/Coniferous

431-                  Forestland, Mixed Deciduous/Coniferous, Coniferous Prevalent (>50% Coniferous)

4311                 Forestland, Mixed Deciduous/Coniferous, Coniferous Prevalent (>50% Coniferous), 10% - 50% Crown Closure

 

 

The following is the code list of the Anderson Classification System modified by the NJ DEP for its land use/land cover data layers. This version contains only codes adopted for the 2002 update in addition to codes used in previous versions.

 

The baseline LU/LC layer of 1986 was originally compiled using a modified Anderson classification at level II with some level III detail.  For the 1995/97 LU/LC project, III and IV level detail was added to the 1100 and 4000 land use categories. For the 2002 LU/LC project, III and IV level detail was added to the 1000, 4000 and 6000 land use categories.  For specific details and descriptions regarding these classes, please refer to ANDERSON2002.doc. 

 

Note that some land use codes and labels will appear only in the 1986 attribute fields. These codes are identified by a single asterisk (*) in the list below. These codes were general land use categories that were broken down into more detailed levels for the update.  However, where a polygon completely changed from one land use category to another, the detailed code could not be retroactively applied to the 1986 category.  There are also several codes that appear only in the 1995 attribute fields, since these categories were not applicable to the 1986 data.  These codes are indicated by a double asterisk (**) in the list below. For 2002 there are several codes added and will appear only in the 2002 attribute fields.  These categories were not applicable to the 1986 or the 1995/97 data.  These codes are indicated by a triple asterisk (***) in the list below.  In some cases, however, the codes developed for 2002 were used to replace or correct a coded value in the "lu95" attribute field in order to prevent misleading land use change detection.  All other codes may appear in either the 1986 data or the 1995/97 data. 

 

Notation of codes:

(*)   = 1986 only

(**)  = 1995/97 update

(***) = 2002 update
