RAW File Data - Line measurement data in native units

Field Name

Datatype

CDCS name

NOTE:

GCDB_ID_Fr

String

none

GCDB_ID of beginning point of measured line. These GCDB_IDs are similar to Meas_GCDB (Refer to CON file dictionary), but more generic.

GCDB_ID_To

String

none

GCDB_ID of ending point of measured line. These GCDB_IDs are similar to Meas_GCDB (Refer to CON file dictionary), but more generic.

Header_data

String

n/a

Free text descriptors of data containing township name, meridian, state, file creation date.

Line_number

String

none

Line number that data occupies in RAW file. The ordering of data lines follows user intuition in grouping and organizing data in a logical set of sequences. Randomizing the order of lines would make a printout of this data unusable for purposes of inspection and quality control.

Meas_bearing_value

Numeric

none

Measured bearing found in source documents. Format is DDMMSS.s

Measured_distance_value

numeric

none

Measured distance found in source documents. Units found through SID value in SID file.

Origin_data

String

n/a

Obsolete field. Origin of local projection used in obsolete software, PCCS

Quad_code_of meas_direction

1-Digit

none

Code indicating the quadrant portion of the measured bearing. There is no accomodation for azimuth values (1-360) which have no quadrant designation. 1=NE; 2=SE; 3=SW; 4=NW.

SID_suffix

String

none, see description below

Additional categorization of lines, appended to Survey_ID. On alphanumeric Survey IDs, a hyphen delimits the ID with the suffix.

Standard values BLM-wide:

  • TIE used on non-boundary lines. Denotes invisibility in coverage. Connector Line
  • LC means Long Chord of curve. Denotes invisibility in coverage. None
  • RP follows Long Chord entry. Invisible line segment to Radius Point. None
  • PBLT Protracted Bearing Line True, an example of a line in an Amended Protraction Diagram. None

There are often arbitrary user-assigned values that separate out different areas within a survey that have differing reliabilities. Ex. 7123-A, 7123-B.

Note: In GMM nomenclature the "SID number" refers to both the Survey_ID and SID_suffix.

Survey_ID

String

source link

Unique alphanumeric identifier that identifies a particular source document for brg/dists There are only local standards for these values. There can be several values for any given survey.
