- This listing contains control for which complete digital -
- data sheets where not provided. The complete data sheets were -
- not provided for the reason listed below. The reason below is -
- associated with a horizontal control Nonpub code shown under -
- the heading 'H' and/or a vertical control Nonpub code shown under -
- the heading 'v' -

- The format of the records are as follows: -
- Pid = Station Permanent Identifier) -
- Name = Station Designation -
- Lat = Approx. Latitude (Degrees, Minutes, truncated Seconds) -
- Lon = Approx. Longitude (Degrees, Minutes, truncated Seconds) -
- O = Horizontal Order -
- o = Vertical Order -
- H = Horizontal Nonpub Code -

- NOTE - Stations found in this listing may still have a valid -
- datasheet produced by use of other publishable values. -
- For example, an ADJUSTED height may be non-publishable -
- but a good GPS height might be found on the datasheet. -
- This listing does not imply that values found on the datasheet -
- are restricted. If it's on the datasheet, use it. -
