Add full COGO functionality to ArcGIS Pro

mhoffman6 — Tue, 22 Aug 2017 21:02:04 GMT

I have been working in ArcGIS Pro to test the migration to ArcGIS Pro from ArcMap. One of the job duties I have is to verify easements, annexations, and other legal descriptions. One of the concerns I have is with the release of the Traverse tool. While it has been nice to work with, currently I am not seeing Grid to Ground Correction functionality as well as the ability to COGO area descriptions into a polygon format. Is there something I am missing with the latest version of ArcGIS pro or is the functionality not there as of yet?

Ground to Grid functionality in ArcMap would have corrected for this error (as much as it is).

See attached image, disregard the polygon as that is for the third portion of my question.

Secondly, is there directional control for non-tangent curves? See my legal description example.

Example: "thence 4.32 feet along the arc of a non-tangent curve to the right, said curve having a radius of 326.00 feet, a delta angle of 00-45'34", and a long chord bearing 74-57'30" East, 4.32 feet to a point of compound curvature"

Currently I have not seen any way to enter curve direction for non-tangent curves in ArcGIS Pro. Is there a tool or command that I am missing here as well?

Third and final question for entering in legal descriptions for areas such as Annexations and Easements (all forms). I have not seen tool functionality or ability to enter in legal descriptions for areas. The polygon that is in the picture is one that I traced over top of the transverse that I created to test the tool. Is there something I am missing here as well?

Thanks.

The lack of a setting for ground-grid correction is a significant frustration, and a barrier to adopting Pro for many workflows.

With the release of the next generation of parcel management, Pro will have the capability to perform ground to grid correction as well as account for a different basis of bearing.

The next release of ArcGIS Pro (2.1) will allow you to construct polygons from lines without having to retrace your lines. This is also be part of the core functionality of parcel management when it's released. Until then you can also use geoprocessing tools to generate polygons from selected lines.

The traverse tool help document provides examples as well curve overrides for non tangent bearings (delta, chord etc.).

Schedule: the parcel manager release date is kept up to date on the ArcGIS Pro Roadmap blog post.

Thanks for communicating the gaps that prevent you from using ArcGIS Pro,

Amir

Amir,

Thank you for the insight and update to this COGO tool and functionality. I still have to receive an answer to my second question as far as non tangent curves go. This is an essential functionality to what we do as I explained above. Will there be directional control much like what we saw in ArcMap COGO functionality in regards to curves 'left' or 'right' drop down. Something that enables this would be appreciated for all legal descriptions that we have to check.

Thank you again for your responsiveness.

Matt

Hello Matt,

You can already specify right and left curves by entering positive and negative radius values in the traverse grid.

If you COGO enable your line feature class you will also get good default symbology and labels in Pro.

Read the help documentation and you will find many enhancements that will make entering a traverse even faster, like:

Tangency is assumed (default)
Use '+' or '-' to enter a 90 degrees angle
Use arithmetic operators when entering distance units, no need to pull out an old calculator
Use shortcuts for quadrant bearings
Much more...

Thanks Amir - I'll look forward to using the ground-grid correction!

Amir,

Do you know how Non-tangent Curves would work under the new Traverse Tool or point me in the right direction. I was able to get tangent curves to function (which the intuitive curve system is nice!), however I am having issues with Non-Tangent Curves still.

AmirBar-Maor — Fri, 01 Sep 2017 20:16:51 GMT

Hi Matt,

The curve begins from the last entered course, use the Curve Overrides which are in this help document topic (scroll down) and you will see the methods in which the orientation of the curve can be defined (tangent bearing / radial bearing / chord bearing...). Enter the appropriate bearing in the direction field.

The topic is copy-pasted (might not be formatted as nicely as the help doc) below::

Curve overrides

Curves described on a plat or plan may not conform to a single set of curve parameters, such as radius and arc length. In the traverse grid, you can override the Bearing, Radius, and curve parameter fields (Arc Length, Chord Length, and Delta Angle) using the following curve parameter overrides:

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

I'm hoping that the functionality of the COGO traverse tool is not complete yet. In Desktop, it was a simple process to input a legal description directly from the surveyor's exhibit and I was able to compare what I entered into COGO verbatim. I am finding it beyond frustrating that I now have to calculate curve overrides an still haven't figured out how to start my line with a curve. I will admit that I am not a 'GIS Expert', and only use the program to input legal description, so the simplicity of the prior functionality was greatly appreciated.

I am happy to hear that we will be able to convert our line to a polygon, but don't understand why the extra step is necessary when the intent is to construct a polygon. Is there somewhere that I can review the logic behind the change? It's always helpful to work through the frustrations of such significant changes when I know there is a method to the madness.

Hello Sandie,

You'll be happy to learn that the traverse functionality is not complete and that there is a "method to the madness". Beyond the learning curve involved with working with a new software / tool, we are driven by customer feedback and ideas. Our suggestion to use the construct polygon tool or geoprocesssing tools such as feature to Polygon" is an interim solution.

If you start your traverse with a curve entry you will have to provide it an orientation (in the direction field).

We also recommend that you run the geoprocessing tool "Enable COGO" on your line feature class and then add it to your map to make benefit of the helpful symbology - it helps both data entry and comparing the deed to the traverse.

For simple traverse entry by "non GIS experts" you can also try (try it live) the web app called "Parcel Drafter".

Thanks for your feedback.

Sandy,

It took me several days with Amir's help to finally get it rolling. The Traverse Tool Documentation isn't super intuitive. However, once you learn it does become easier to use.

One example is for non tangent curves:

Non-tangent Curves Example: For non-tangent curves such as 99.06 feet on the arc of a curve to the right, said curve having a radius of 516.00 feet, a central angle of 11°00' 00", a chord bearing of North 49° 13' 15" West, a chord length of 98.91 feet."

To enter a non-tangent curve using chord bearing using the description above:

Here is what you would type:

1. Direction Column: 49.1315 cb ENTER

2. Distance Column: TAB

3. Radius: 516.00 (right turns are positive, left are negative) ENTER

4. Chord Bearing: 98.91 ENTER

I added this to our own internal documentation to help clear this issue up.

I'll give it a try Amir. Thanks for the reply.

SandieHewston — Mon, 25 Sep 2017 22:24:30 GMT

Thanks for the hints Matthew.

I'll see if this helps. I've never had to convert from what our surveyors provide, so this all seems rather counter-intuitive to go away from legal descriptions. That is probably my US Centric as opposed to global thinking mind. I'll keep working on it.

Good Morning,

So I am new to pro but I would have to say that the COGO Functionality is highly lacking at the new release. I have been entering traverse data and using cogo tools since release 6 on a unix machine and would like to say major ball dropped on the COGO side in PRO. I do not use the Parcel Fabric and have no plans migrating that way I have always uses the tools that ArcMap provided to do my parcel editing.

Proportion

Ground to Grid Correction

Offset Line

culdesac

cogoarea

Heck I use the curve calculator when I am missing data all the time. ARCpro does a great job making serving data and tools easier but the have forgotten about the people who edit and create the data in the back office on a day to day basis.

Please do not forget us creators of data and improve the cogo functionality in pro.

the formats for entering the data above suck you try entering a 300 leg traverse off an old document using those methods take you a week.

89.4523-1 400 should be the only entry needed to create a line with a bearing of N 89 deg 45 min 23sds E a distance of 400 feet.

negative and positive radius where did that come from I have received tons of information from surveyors about 27 years worth and I have never seen curves identified as a negative or a positive radius.

please bring all COGO functionality in.

Thanks

Hello Bob Folsom,

The missing functionality you have stated will be introduced to Pro in future releases as well as new functionality that never existed. This includes:

Proportion
Ground to Grid correction
Basis of bearing correction
Offset line
Cul de sac
COGO area
Curve calculator
More...

Our goal is to make you and other map technicians that enter data from measurements on a daily basis more efficient by reducing mouse clicks and relying on a single hand to enter the data.

We understand that it might take a while to get used to a more efficient methodology after working in ArcMap for so many years.

If you are using the latest release of Pro you will find you can modify existing traverse and save your edits at any point of time. Run the geoprocessing tool "Enable COGO", then add the line feature class to your map and you get a symbology and labeling that is designed for COGO entry. It also allows you to perform arithmetic operations within the traverse grid.

In the meantime please continue to provide feedback and enter new ideas for the missing functionality so everybody can vote on them. This helps the development team to prioritize the implementation schedule.

Hey while your at it ESRI..... can we save traverses as text files again. That was sure nice.

Re: Add full COGO functionality to ArcGIS Pro

mhoffman6 — Thu, 08 Mar 2018 21:19:13 GMT

Hello All just wanted to give an update. I am pretty happy with how ArcGIS Pro has come along. There is still a significant amount of work (as Amir has stated). However as such, we have begun to COGO and create polygons within ArcGIS Pro. If ESRI continues to include functionality such as the Utility Networks (former Geometric Networks) and the Grid to Ground Corrections. I can see Pro becoming a really good asset.

If anyone has any questions please let me know n here I would be glad to help explain what we have done.
