General Guidelines

  • Field Help: Roll cursor over field titles. If underline appears, click for field information.
  • Forms buttons: Use forms buttons, links, and tabs to navigate wherever possible.

-       Avoid browser back and forward arrows unless necessary.

  • Re-sort Lists: Click underlined column headings to re-sort a list by that column.

-       Click again to switch between ascending and descending sort order.

  • Required entry: Fields with * are required fields. Data must be entered.

  • Is displayed in the Feature box in the upper left of each detail page.

Return to Contents

Names Rules

  • One feature – One official name. No exceptions.
  • Defined by function – not composition, size, or location. Example:

-       Fisher Church and Fisher School – two features in same building with identical coordinates but different functions are two different features.

  • Several names for the same feature?

-       Determine one official name.

-       All others are variants.

  • A variant is any name other than the official name. Examples:

-       Historical name that is no longer official.

-       Name less used than the official name but recognized locally.

-       Name incorrectly recorded on a map or in a document but in the public domain.

-       Misspelling of an official name.

Note: An abbreviation of the official name is NOT to be recorded as a variant.

  • The following parenthetical expressions only are allowed following the name.

-       “(Historical)” – See Designate Historical Feature.

-        “(Not Official)” – a name approved by a State that may be on State maps, but has no Federal recognition as official and shall not be used in Federal products. Not a variant. (Only 20 records exist.)

  • Natural Features, Reservoirs, Canals

-       New name or name change usually requires Board on Geographic Names decision.

-       Note: Feature names with a Board decision cannot be changed. See Decisions tab.

  • Abbreviations: Spell them out.

-       Except abbreviated features specified in law.

  • Generics: Almost all features should include a generic. Examples:

-       Mount Saint Helens

-       J C Thomas School

-       Coleville Mountain

-       Lake Mead

  • Generics Exception: Populated Places might not include a generic term. Examples:

-       Chicago

-       Mount Pleasant (The word “Mount” is part of the name, not a generic in this case.)

  • Definite articles usually are lower case if not the first word in the name.

-       Examples: with, for, the, our, …

-       Woods, Lake of the; Hole-in-the-Wall

  • Apostrophes

-       Use only for administrative (not natural) features.

-       Remove genitive or possessive apostrophes from names of natural features.

Ÿ  Sequence counties for linear features (streams, valleys, arroyos) from mouth to source.

-       Each county is entered only once even if the feature enters, exits, and reenters the county.

Ÿ  Ensure complete coverage of areal features in more than one county (parks, national forests, populated places, etc.).

Ÿ  Sequence counties for areal features generally from the primary county outward in the most convenient sequence. There are no set rules.

Ÿ  Counties other than the primary county are secondary counties.

Return to Contents

Coordinates Sequence Rules

Ÿ  Point sequence number 1 is always the primary point and determines the primary State and county.

Ÿ  Point features have a single set of coordinates.

Ÿ  Sequence points for linear features (streams, valleys, arroyos) from mouth to source.

-       Each map (cell) is represented by only one point even if the feature enters, exits, and reenters the map.

-       Exception: Source coordinates for a linear feature may be in the same map as the primary coordinates.

-       The highest sequence number (if known) is the source of a linear feature.

Ÿ  Ensure complete coverage of areal features in more than one map (parks, national forests, populated places, etc.).

-       Sequence points for areal features generally from the primary map outward in the most convenient sequence. There are no set rules.

Ÿ  Points other than the primary point are secondary points.
