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.
