Parcel drafter misclose measurement issue

Hello Friends,

I am looking at the Parcel drafter widget here https://statelocaltryit.maps.arcgis.com/apps/webappviewer/index.html?id=3788f989438241ba8a094ad67915... . I have a question regarding misclose bearing and distance calculations. In the below screen shot I draw a polygon with listed Bearing, length and radius, although the polygon doesn't appear to be close, misclose distance and bearing is displayed as 0.

where as in the below screen shot I draw a polygon with the listed measures, the polygon appears to be closed visually but it shows misclose distance and bearing > 0

Any clarification and help on this will be much appreciated.

 

Thanks,

Rauf

I get some really strange results in the Parcel Drafter when there are curves sometimes.

From what I can tell, the misclose seems to use the chord length when it calculates the misclose, regardless of whether you have your settings set to arc length.

Interestingly, if I look at that line when it completes, it shows a negative distance.

And trying to manually enter a negative distance:

I would suppose this to be a bug. Until an official fix is applied, you could just use the chord lengths, if you have them.

Hi Josh,

Thanks for your explanation. Is there any way we can reach out to Esri and bring this to their notice ?

Thanks,

I'd just reach out to Support, and they can forward the issue to the relevant team.

Hi @jcarlson ,

I found another issue with the widget, wanted to check with you whether you have any idea about it?

If I use arc length I am seeing the parcel getting closed and have certain misclose bearing, distance values but when I enter equivalent chord length in chord length mode, the parcel is not getting closed and the misclose calculations are also different.

1. arc length = 98, radius=45, it is in arc length mode.

2. chord length = 79.75 (when arc length = 98), radius = 45, it is in chord length mode but you will see the misclose calculation is different and parcel not getting closed.

Strange! I'm afraid I don't have any guesses on this, but have seen that kind of behavior in the past.

Hi Rauf,

 

Did you ever create the metes and bounds tool in the ArcGIS Javascript API? I am looking to do something similar and would like to hear your progress.

 

Thanks,

Hi Flinn,

I created the tool. Esri team resolved the issue with their Traverse tool,
you can download the Traverse widget once you install the Webapp builder on
your machine and take a look at the code and take whatever pieces you need
from it and create a similar widget. You can take a look at the Esri
Traverse widget here
