SD File Data - Error Estimate data prepared for Least Square Analysis

Field Name

Datatype

CDCS name

NOTE:

End_of_angle_segment_code

1-Digit

n/a

Code indicating the end of the angle segment of this file format.

0=more data to read; 1=end of angle segment.

End_of_control_segment_code

1-Digit

n/a

Code indicating the end of the control point error estimate segment of this file format.

0=more data to read; 1=end of control segment.

End_of_direction_segment_code

1-Digit

n/a

Code indicating the end of the direction segment of this file format.

0=more data to read; 1=end of direction segment.

End_of_distance_segment_code

1-Integer

n/a

Code indicating the end of the distance segment of this file format.

0=more data to read; 1=end of control segment.

Err_Est_Measured_angle_at_PtID

String

none

GCDB_ID at apex between lines relating to angle data.

Err_Est_Measured_angle_backsight_PtID

String

none

GCDB_ID of backsight point of line relating to angle data.

Err_Est_Measured_angle_foresight_PtID

String

none

GCDB_ID of foresight point of line relating to angle data.

Err_Est_Measured_dir

Numeric

none

Error estimate for Measured direction of line. North Azimuth clockwise value.

Format: DDD MM SS.ss

Err_Est_Measured_dir_GCDB_ID_Fr

String

none

GCDB_ID of beginning point of line relating to direction measurement.

Err_Est_Measured_dir_GCDB_ID_To

String

none

GCDB_ID of ending point of line relating to direction measurement.

Err_Est_Measured_dist_GCDB_ID_Fr

String

none

GCDB_ID of beginning point of line relating to distance data

Err_Est_Measured_dist_GCDB_ID_To

String

none

GCDB_ID of ending point of line relating to distance data.

GCDB_ID

String

none

Unique alphanumeric ID that helps identify the function of a particular point. There is a 6-character standard for points within the PLSS. GMM uses this standard for subdivision of sections. BLM catalogues non-PLSS corners into broad categories using the first three characters of a 6-character ID.

X_err_est

Numeric

none

Error estimate determined for X_measurement_dist in LSA file. Feet units.

Y_err_est

Numeric

none

Error estimate determined for Y_measurement_dist in LSA file. Feet units.
