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 of ending point of measured line. These GCDB_IDs are similar to Meas_GCDB (Refer to CON file dictionary), but more generic.
Free text descriptors of data containing township name, meridian, state, file creation date.
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.
Measured bearing found in source documents. Format is DDMMSS.s
Measured distance found in source documents. Units found through SID value in SID file.
Obsolete field. Origin of local projection used in obsolete software, PCCS
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.
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.
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.
