LSA File Data Measured data prepared for Least Square Analysis

 

Field Name

Datatype

CDCS name

NOTE

Meas_GCDB_ID

String

none

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

X_measurement_SPC

Numeric

none

Positional value measured from a physical monument. State plane coordinates, current zone.

Y_measurement_SPC

Numeric

none

Positional value measured from a physical monument. State plane coordinates, current zone

End_of_control_segment_code

1Digit

n/a

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

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

Measured_distance_GCDB_ID_Fr

String

none

GCDB_ID of beginning point of line relating to distance data.

Measured_distance_GCDB_ID_To

String

none

GCDB_ID of ending point of line relating to distance data

Measured_distance_value

Numeric

none

Record distance value in feet units.

End_of_distance_segment_code

1Digit

n/a

Code indicating the end of the distance segment of this file format. Zero or one.

Measured_angle_backsight_GCDB_ID

String

none

GCDB_ID of backsight point of line relating to angle data.

Measured_angle_foresight_GCDB_ID

String

none

GCDB_ID of foresight point of line relating to angle data.

Measured_angle_value

String

none

Record angle measured. Format DDD MM SS.ss

End_of_angle_segment_code

1Integer

n/a

Code indicating the end of the angle segment of this file format. Zero or one.

Measured_direction_GCDB_ID_Fr

String

none

GCDB_ID of beginning point of line relating to direction measurement.

Measured_direction_GCDB_ID_To

String

none

GCDB_ID of ending point of line relating to direction measurement.

Measured_direction_value

Numeric

none

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

Format DDD MM SS.ss

End_of_direction_segment_code

1Digit

n/a

Code indicating the end of the direction segment of this file format. Zero or one

Adj_GCDB_ID

String

none

Same ID scheme of Meas_GCDB_ID, but applying to points that have been adjusted. ID values found in Meas_GCDB_ID will be repeated in this section, but with adjusted coordinate values.

X_adjusted_coord_value

Numeric

none

Positional value resulting from a least square adjustment. Feet units

Y_adjusted_coord_value

Numeric

none

Positional value resulting from a least square adjustment. Feet units.

End_of_adjusted_coord_segment_code

1Digit

n/a

Code indicating the end of the adjusted coordinate segment of this file format. Zero or one.
