  7. How does the data set describe geographic features?

    PlantAssociation
    Potential Natural Vegetation (PNV) refers to the plant community that would be established if all successional sequences were completed without human interference under the present environmental conditions, including those created by humans. (Source: Forest Service GIS Data Dictionary (2004))

    FID
    Internal feature number. (Source: ESRI)

    Sequential unique whole numbers that are automatically generated.

    SHAPE
    Feature geometry. (Source: ESRI)

    Coordinates defining the features.

    PNV_CN
    Control Number generated by Oracle to identify uniquely each PNV map unit across all Forest Service units. This value is automatically populated in the coverage when the database is synchronized with the coverage and is used to identify unique map units across the landscape. This item is used to join the polygon GIS features to the corresponding rows in the Oracle views by matching with the column MAPU_CN column in the view. (Source: Forest Service GIS Data Dictionary (2004))

    ValueDefinition
    Example: 99210277A unique code generated by Oracle.

    MAP_UNIT_S

    PROJECT
    Code value (abbreviation or mnemonic) for the project to which the map units belong. (Source: Forest Service GIS Data Dictionary (2004))

    ValueDefinition
    Example: BT-EUILocally stewarded value.

    REV_DATE
    Date of feature creation or latest update. (Source: Forest Service Feature Level Metadata Standard)

    DATA_SOURC

    ACCURACY
    Distance (+/-), in dataset distance units, of expected difference between feature and real world object locations. (Source: Forest Service Feature Level Metadata Standard)

    SHAPE_Leng

    SHAPE_Area
    Area of feature in internal units squared. (Source: ESRI)

    Positive real numbers that are automatically generated.

Why was the data set created?

For display and analysis of ecoclass or plant associations as defined in "Plant Associations of the Central Oregon Pumice" by Hopkins and Volland. This layer is a combination of the PAG coverage from the Winema library and the ecoclass coverage from the Fremont library.

    Type_of_Source_Media: computer program
    Source_Scale_Denominator: 1:24000
    Source_Contribution:
    Legacy layers that may be termed either PNC or PNV at the local level. This layer is intended to be a "legacy" layer.
