How to COGO a Traverse in ArcGIS Pro?

AmirBar-Maor

This video is a quick introduction to COGOing a traverse in ArcGIS Pro.

For more help and examples read the help documentation.

See previous video on GeoNet to learn how to Enable COGO on a line feature class (it's really easy).

Hi Amir,

Thank you for the video demos.

Can you please provide a status update here for the related ideas listed below?

Your reply will help determine ArcPro adoption timeline in enterprise deployment with this recent poll.

ArcGIS Pro Adjust Traverse

Add full COGO functionality to ArcGIS Pro

ArcGIS Pro support for importing and exporting traverse files

Hi Bill,

There are many ideas expressed on those threads, which I have tried to some up here:

Ground to Grid and basis of bearing correction have been implemented in ArcGIS Pro 2.3.
Polygon and line division,, including the proportioning of the misclose have been implemented with ArcGIS pro 2.3.
You can enter non tangent curves using the traverse overrides (see below).
You can perform arithmetic operations on distance units within the traverse itself.
COGO area will be exposed in ArcGIS Pro 2.4 as well as an parcel attribute.
Importing and exporting traverse files is under consideration with high likelihood to be implemented.
Copy parallel as well as the buffer tool can be used to offset a line.
Curve fillet tool has been implemented as part of ArcGIS Pro 2.3.
Cul de suc entry, curve calculator and other less common tools will be implemented in subsequent releases.

Override	Keystroke	Use in grid field	Example
Tangent bearing	tb or TB	Bearing	41-56-06-4tb (using quadrant bearing)
Radial bearing	rb or RB	Bearing	41-56-06rb (using quadrant bearing)
Chord bearing	cb or CB	Bearing	41-56-06cb (using quadrant bearing)
Chord length	c or C	Arc Length, Delta Angle	25.01c
Delta (central angle)	d or D	Arc Length, Chord Length	90-59-59d
Arc length	A or a	Chord Length, Delta Angle	25.01a

Hello,

We appreciate the video.

Can you help with entry of this traverse using ArcGIS Pro 2.8.2?

Segment: Curve

Length: 355.26' Radius: 7959.44'
Delta: 002°33'26" Tangent: 177.66'
Chord: 355.23' Course: S87° 04' 17"W
Course In: S01° 39' 00"E Course Out: N04° 12' 26"W

"...THENCE leaving said south right of way line South 00°52' 45" East, a distance of 747.35 feet, to the northerly right of way line of roadway and the beginning of a non-tangent curve to the left from which point the radius point bears South 1°39'00" East; THENCE 355.26 feet along said northerly right of way line the arc of said curve to the left, having a radius of 7959.44 feet, through a central angle of 2°33'26" and a chord bearing of South 87°04'17" West; ..."

Thanks for any help!

Hello,

To enter this into the traverse it would look like screenshot below, you will have to use the RB, radial bearing override for the non tangent curve described here:

"a non-tangent curve to the left from which point the radius point bears South 1°39'00" East"

To check this you can use the Direction Distance measure tool to verify the chord direction and distance are correct:

"Chord: 355.23' Course: S87° 04' 17"W"

Oh. OK. Thank you! Will try this!
