    GU_Country

    The geographic area of an independent, self-governing, political entity. (Source: Data Dictionary for Govermental Units. Draft Standards Database, 2013. September 25.)


    GU_CountyOrEquivalent

    The primary division of a state or state equivalent area. The primary divisions of 48 states are termed County, but other terms are used such as Borough in Alaska, Parish in Louisiana, and Municipio in Puerto Rico. This feature includes independent cities, which are incorporated places that are not part of any county. (Source: Data Dictionary for Govermental Units. Draft Standards Database, 2013. September 25.)


    GU_IncorporatedPlace

    A type of governmental unit, incorporated under state law as a city, town (except in New England, New York, and Wisconsin), borough (except in Alaska and New York), or village, generally to provide a wide array of specific governmental services for a concentration of people within legally prescribed boundaries. New for Census 2000 are "city and borough" and "municipality," which serve as both place- and county-level entities in Alaska. A few incorporated places do not have a legal description. See consolidated city, governmental unit, independent city, independent place, place. (Source: Data Dictionary for Govermental Units. Draft Standards Database, 2013. September 25.)


    GU_Jurisdictional

    An administrative unit that defines the scope of a public, private, or nonprofit organization jurisdiction for purposes other than use regulation, zoning, or reserve. (Source: Data Dictionary for Govermental Units. Draft Standards Database, 2013. September 25.)


    GU_MinorCivilDivision

    A type of governmental unit that is the primary legal subdivision of a county or statistically equivalent entity in many states and statistically equivalent entities, created to govern or administer an area rather than a specific population. MCDs are identified by a variety of terms, such as town, township, or district. The U.S. Census Bureau recognizes MCDs in 28 states, the District of Columbia, Puerto Rico, and the Island Areas. In 20 states and American Samoa, all or many MCDs are active general-purpose governmental units. Many MCDs are not general-purpose governmental units, and therefore do not have elected officials to carry out legal functions; instead, they serve as nonfunctioning administrative entities. (Source: Data Dictionary for Govermental Units. Draft Standards Database, 2013. September 25.)


    GU_NativeAmericanArea

    A U.S. Census Bureau term referring to these entity types: American Indian reservation, American Indian off-reservation trust land, tribal subdivision, Oklahoma tribal statistical area, state designated American Indian statistical area, Alaska Native Regional Corporation, Alaska Native village, Alaska Native village statistical area, and Hawaiian home land.

    Other citation details:
    The international boundary between Mexico and the United States, defined as a joint venture between the U.S. Department of Agriculture (USDA) and the Instituto Nacional de Estadistica y Geografia of Mexico (INEGI), resulted in an unofficial United States-Mexico boundary dataset that was further enhanced by the U.S. Geological Survey's Border Environmental Health Initiative (BEHI). With the data frame scale set to 1:5,000 in ArcMap, the center of the Rio Grande/Rio Bravo was digitized using the NAIP 2004 Imagery. In areas with dense stands of salt cedar (bounding box = UL -104.714 30.038, UR -104.664 30.037, LR -104.666 29.933, LL -104.717 29.934; NAD83), the center of the channel was difficult, and sometimes impossible, to easily determine. To determine the location of the boundary, the GIS analyst compared the location of the line in the INEGI 1:250K Limited feature class with the NAIP 2004 Imagery and adjusted the boundary to the image, thus, the delineation of the international boundary is less certain in these areas. The remaining part of the border was extracted from the INEGI 1:250K Limited feature class and appended to the line feature class created along the Rio Grande/Rio Bravo. The U.S. Geological Survey reviewed the original USDA data against 2007 NAIP imagery and further edited 9 line segments in the Rio Grande areas to conform to National Map Accuracy Standards.it>

    Section boundaries were generated from geodetic latitude and longitude coordinate pairs as recorded on BLM's official protraction diagrams of the state of Alaska. The SDMS_PROD protraction tables were modified to include pro_pt83, section83, and township83. The latitude and longitude values in the pro_pt83 table were transformed from geographic NAD27 coordinates to geographic NAD83 coordinates using NADCON for Alaska. The Informix Section83 table is a spatially-enabled table that contains all of the protraction information for each of the 655,483 sections. Section shapes are stored as NAD83 geographic multipolygons. Each section was individually constructed from NAD83 geographic pro_pt (Protracted Point) table and is fully densified by including all township/section offset corners from adjacent township/sections.

  2. What changes have been made?

    Date: 20121105 (change 1 of 1)

    The data for this product are created as follows. All geospatial content is taken from national geospatial databases under the stewardship of USGS data programs. The NAIP imagery is provided by a seamless tile service that delivers image data at the resolution and quality of the source imagery. The vector data, including grids and collar information, are processed using ESRI ArcGIS software and exported. Map formatting is performed using a custom application, which includes post-processing to embed the metadata XML document.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Cartographic content is derived from USGS national geospatial databases. The data is owned and hosted by the USGS, but does not preclude using data sources owned and hosted by other organizations, provided that these sources have been approved by the USGS data program.


  2. How accurate are the geographic locations?

    This map product is compiled to meet National Map Accuracy Standards (NMAS). NMAS horizontal accuracy requires that at least 90 percent of well-defined points tested are within 0.02 inch of the true position. In this product, the projection line, grids, and orthoimage are believed to meet NMAS. Positional accuracy of the other data layers is less controllable because of diversity of data sources, and may not meet NMAS.


  3. How accurate are the heights or depths?

    Vertical accuracy is not applicable to this dataset.


  4. Where are the gaps in the data? What is missing?

    Each layer is extracted from the USGS national geospatial databases.


  5. How consistent are the relationships among the observations, including topology?

    This product is a layered data datbase. The data is extracted and codified according to USGS standards.
