Title:
Land Use & Land Cover, 1997, Lower Payette River Basin, Idaho

Abstract:
Land use and land cover data developed using image interpretation of
scanned, map registered, and mosaicked color infrared airphotos.

Supplemental information:
Procedures_Used:
Color infrared images were analyzed using standard photo interpretation
techniques.  The images were produced from scanned, map registered and
mosaicked 1:24,000 scale color infrared aerial photographs. A suite of
ARC/INFO AMLs was developed and used to conduct the image interpretation.

Revisions:
1

Reviews_Applied_to_Data:
The land use and land cover data was plotted at 1:24,000 scale and
the maps were verified in the field.

    cover class. The classes are described below:
    
    Land Use & Land Cover Classes
    Definitions and Descriptions
    
    1. URBAN OR BUILT-UP LAND
    
    11. Residential--Farmstead
    
    Farmsteads are homes, generally isolated from other residences, associated
    with agricultural fields. This includes vegetable gardens, yards, barns,
    other out-buildings and storage areas.
    
    12. Residential--Old Urban/High Density
    
    Old urban is high-density urban residential land used for homes that are
    spaced closely, set back from the street, and arranged in orderly,
    rectangular patterns on lots less than 1/2 acre in size. Yards have mature
    trees.  Includes high density categories such as trailer parks and
    apartments.
    
    13. Residential--New Subdivision
    
    New subdivision land is used for generally high density residences less
    than 20 years old.  Houses are closely spaced, set back from the street
    and often are in non-geometric patterns.  Cul-de-sacs are common.
    Trees are immature. Lot size is 1/8 to 1/2 acre.
    
    14. Residential--Rural
    
    Rural residential is open, very light density residential. Lots are
    generally between one and five acres.
    
    15. Commercial & Industrial
    
    Land used for manufacture, distribution and merchandising goods and
    services.  Goods manufactured include small appliances, electronics and
    other secondary products.  Merchandising areas include stores, offices,
    gas stations, restaurants, parking areas, motels and small warehouses.
    This land is usually located in strips along heavily traveled routes,
    in the core area in the center of a city or in large shopping centers.
    
    16. Public
    
    Urban public land includes parks, colleges, churches, hospitals,
    cemeteries, schools and associated grounds; state and federal facilities.
    
    17. Recreation
    
    Recreation areas include golf courses, stadiums, driving ranges, race
    tracks, campgrounds and other areas for outdoor recreation.
    
    18. Transportation
    
    Transportation corridors include railroad rights-of-way and marshaling
    yards and major highways that do not follow Public Land Survey System
    lines.
    
    19. Sewage Treatment
    
    Sewage treatment plants including settling ponds, lagoons, filter beds
    and associated buildings.
    
    2. AGRICULTURAL LAND
    
    21. Irrigated Cropland and Pasture
    
    Land presently being irrigated, land irrigated during the present growing
    season or land fallowed either from water shortage or crop rotation. With
    the exception of alfalfa, crops grown are harvested once per growing
    season.  A crop can be presently in the field, recently harvested or the
    field can be prepped for cultivation. Land that is in transition from
    irrigated to developed should be called "Transition Agriculture".
    
    22. Perennial
    
    Perennial includes orchards, vineyards and nurseries.
    
    23. Idle
    
    Land out of production for more than one season, but not permanently
    abandoned to agriculture. The irrigation infrastructure remains intact.
    
    24. Land in Transition (farmland to urban or built-up land)
    
    This is agricultural land that usually is in the process of being developed
    for housing, commercial use or other non-agricultural purposes. Generally
    the land has identifiable agricultural patterns, but is not prepped for a
    crop.  Often, the land shows disturbance other than that associated with
    farming.  The land is frequently found next to or mixed with land on which
    construction is occurring.
    
    25. Feedlot/Stockyard
    
    Land used for feeding, processing or warehousing of animals, such as
    cattle or sheep, bound for market. Includes pens, feeding areas, slurry
    lagoons, manure piles and associated facilities. This does not include any
    associated pasture or crop land.
    
    26. Dairy
    
    Land used for the purpose of dairy production from cows or goats.
    Includes barns, storage areas, feeding areas, slurry lagoons, manure piles
    and associated facilities. This does not include any associated pasture
    or crop land.
    
    27. Abandoned Agriculture
    
    Land taken out of production. Land cover may be annual weeds or young
    perennial shrubs. There should be some evidence of the land having been
    irrigated at some time in the past, such as stacked pipe, a faint
    circular scar or overgrown ditches.
    
    28. Other Agricultural Land
    
    Agricultural land not otherwise described.
    
    3. Rangeland
    
    Land that supports wild vegetation: grasses forbs and shrubs. It may be
    grazed, but is not irrigated.
    
    4. Water
    
    Open bodies of water, including artificial lakes and ponds, reservoirs,
    settling ponds and rivers. This does not include sewage or slurry lagoons.
    
    5. Wetland/Riparian
    
    Land that is identifiable on mid-summer photography as being either wet
    or adjacent to a water-body.
    
    6. Barren Land
    
    Any land that is devoid of vegetation. This includes lave flows, sand
    and gravel bars and rock outcrops. Areas that have recently been scraped
    bare by heavy equipment should be called "Land in Transition" (# 24)
    
    7. Canal
    
    Major feeder canals in the area. This includes the actual canal plus any
    associated right-of-way lands and roads that may be evident. This class
    includes, but is not limited to, the New York, Ridenbaugh, Phyllis, Deer
    Flat Low Line, Golden Gate, Riverside, Middleton and Farmers' Union canals.
