1 Integer

Digit indicating which geometric process is used.

1= Traverse/proportion; 2=Intersection; 3=Addaline; proposed 0=make line invisible

String

ID of point to be created by process.

String

ID of point onto which the process is applied. Processes involving intersections will involve an additional "secondary line".

String

ID of point defining the endpoint in an addaline process OR defining the bearing through inverse from the Primary_line_GCDB_ID_from. Processes involving intersections will involve an additional "secondary line". If null, then a Primary_line_direction value must exist.

String

ID of point defining the point of the "point slope" equation of the second line of intersection.

String

ID of point defining the slope of the "point slope" equation of the second line of intersection, by way of inverse from the Secondary_line_GCDB_ID_from. If null, then a Primary_line_direction value must exist.

Digit + Numeric

Constant value defining slope in "point slope" equation of line for traverse/proportion or primary line of intersection. GMM format is digit ranging from 14 indicating quadrant followed by numeric value indication bearing value, format DD.MMSS. A more flexible format would be to have 0 in quadrant spot indicating azimuth and use DDD.MMSS as bearing/azimuth value

Digit

Code indicating whether direction is referenced to geodetic or plane surface. Applied to line of traverse/proportion or to primary line of intersection. Format 1=geodetic line; 2=plane line.

Digit + Numeric

Identical to Primary_line_direction, but applied to secondary intersect line

1 Integer

Identical to Primary_line_direction_surface_code, but applied to secondary intersect line.

Numeric

Distance to traverse from Primary_line_GCDB_ID along defined direction. If process is proportion, then this "record" distance is divided by the "record" sum distance in the Primary_line_sum_distance field to then applied to the inversed distance between the two Primary_line_GCDB_IDs. Distance value of 0 indicates point should be put at midpoint.

Numeric

Distance representing the sum record distance to be used with the Primary_line_distance to achieve proper proportion.

Numeric

Distance to traverse from Secondary_line_GCDB_ID along defined direction. If process is proportion, then this "record" distance is divided by the "record" sum distance in the Secondary_line_sum_distance field to then applied to the inversed distance between the two Secondary_line_GCDB_IDs. Distance value of 0 indicates point should be put at midpoint.

Numeric

Distance representing the sum record distance to be used with the Secondary_line_distance to achieve proper proportion.

String

The direction of a traverse/proprtion line or the primary line of an intersection can be defined as parallel to another line, defined by the GCDB_IDs of its endpoints

String

The direction of a traverse/proprtion line or the primary line of an intersection can be defined as parallel to another line, defined by the GCDB_IDs of its endpoints

String

The Secondary_line_parallel_to/from_IDs are identical in purpose to the Primary_line_parallel_

to/from_IDs, but applied to the secondary line of an intersection.

String

The direction of a traverse/proprtion line or the primary line of an intersection can be defined as a mean bearing between two lines, but weighted as to the resulting line’s position between the two controlling lines. This "weighted mean bearing" is much like a bisect.

String

The Secondary_line_WtdMnBrg_#__to/from_IDs are identical in purpose to the Primary_line_WtdMnBrg_#_to/from_IDs, but applied to the secondary line of an intersection.
