What does this data set describe?

BLM OR Oregon Washington State Boundary Polygon

state_poly: This theme shows the jurisdictional and cartographic state perimeters for Oregon and Washington.

Supplemental information:
BLM (Bureau of Land Management), CFF (Cartographic Feature File), DLG (Digital Line Graph), DNR (Washington Department of Natural Resources), DRG (Digital Raster Graphic), FIPS (Federal Information Processing Standard), GCD (Geographic Coordinate Database layer), GCDB (Geographic Coordinate Data Base), HYD (WODDB Hydrologic Features layer), LLI (Landlines layer), USFS (U.S. Forest Service), USGS (U.S. Geological Survey), WODDB (Western Oregon Digital Data Base). The POCA layer is an integrated set of geographic- referencing data covering the state of Washington. It is derived from land surveys, DNR orthophotos, USGS 7.5' quadrangles, and DNR tract books.

  2. What changes have been made?

    Date: 20010801 (change 1 of 2)
    BLM contractor used the cited sources (see source information) to extract the desired line work and create the new coverage. This was accomplished in ARCEDIT using the SELECT & PUT commands. The coverage was then cleaned, built for topology and projected to Lambert Conformal Conic. All line work was ultimately snapped to GCDB points where available.

    Date: 20050101 (change 2 of 2)
    Original coverage version of the state boundary dataset was loaded into the Oregon Washington Corporate SDE instance as two separate feature classes (Line & Polygon). This SDE data is now considered the master version.
