Citation_Information:

Originator: The original USGS 1990 land use and land cover layer was developed by the US Geological Survey. Rr_landcover.shp was created by Circuit Rider Productions, Inc. Rr_landcover represents the portion of the layer within the Russian River basin. This metadata file incorporates information that is specific to this layer as well as information that is available in the original metadata file for the lancover change layer (general_meta.txt). The portions of this metadata file that borrow text from general_meta.txt are indicated in quotation marks.

Description:

Abstract: "This is land use/ land cover digital data collected by USGS and converted to ARC/INFO by the EPA. This data is useful for environmental assessment of land use patterns with respect to water quality analysis, growth management, and other types of environmental impact assessment."

Purpose:

"Applications that use this data Land use and land cover data LU/LC collected by the USGS NMD is useful for environmental assessment of land use patterns with respect to water quality analysis, growth management, and other types of environmental impact assessment.
Intended use of data Data are meant to be used by quadrangle, or among adjacent quadrangles where temporally contiguous. Can be used in any geographic application where intermediate scale land use data are appropriate and the dates are representative."

Supplemental Information:

" U.S. Geological Survey, 1990. Land use and land cover digital data from 1:250,000- and 1:100,000-scale maps. Data User Guide 4. Reston, Virginia."

 

"Limitations of data Each quadrangle of land use data has a different representative date. Date ranges from mid 1970s to early 1980s are common. When joined together these quadrangles will not likely match along edges due to differences in interpretation and time coverage. Edges of each map file were manually digitized and may not join neighboring maps. If GIRASNEAT program has been applied (see LOG at end) then edges have been mathematically recalculated to join without overlap or gaps in coverage with adjacent maps."

"Attribute discussion

The GIRAS series can include several themes of spatial data. The most common, described here, is the land use and land cover data. Land use was mapped and coded using the Anderson classification system (Anderson and
others, 1976) which is a hierarchical system of general (level 1) to more specific (level 2) characterization. Some agencies have taken this to a level 3 classification -- but this has not been done in the GIRAS series.

The salient attribute managed for this polygon data set in the polygon attribute table (PAT) is the column named LUCODE containing the Anderson level 2 classification. The first digit represents the level one value and the second digit (ones place) represents the subdivision of the level 1 or level 2 value.

The Anderson land use codes are:

Level 1 Level 2
------- -------
1 Urban or built-up land
11 Residental
12 Commercial and services
13 Industrial
14 Transportation, communication, utilities
15 Industrial and commercial complexes
16 Mixed urban or built-up land
17 Other urban or built-up land

2 Agricultural land
21 Cropland and pasture
22 Orchards, groves, vineyards, nurseries
and ornamental horticultural areas
23 Confined feeeding operations
24 Other agricultural land

3 Rangeland
31 Herbaceous rangeland
32 Shrub and brush rangeland
33 Mixed rangeland

4 Forest land
41 Deciduous forest land
42 Evergreen forest land
43 Mixed forest land

5 Water
51 Streams and canals
52 Lakes
53 Reservoirs
54 Bays and estuaries

6 Wetland
61 Forested wetland
62 Nonforested wetland

7 Barren land
71 Dry salt flats
72 Beaches
73 Sandy areas not beaches
74 Bare exposed rock
75 Strip mines, quarries, gravel pits
76 Transitional areas

8 Tundra
81 Shrub and brush tundra
82 Herbaceous tundra
83 Bare ground
84 Wet tundra
85 Mixed tundra

9 Perennial snow or ice
