Locate Depressions Tool - Maximum Distance to Connection

JenniferBorlick

I'm in ArcGIS Pro 3.6.3

I'm using the Locate Depressions to find kettles and depressions countywide. I keep getting caught up on "Maximum Distance to Connection." Looking at the documentation, it says that it's optional and "This parameter will only be applied if a value is specified for it." There is no way to NOT specify a parameter. It always has the default. If I click in the field and delete the number, it comes back as soon as I click or tab out of the field. I have a minimum area defined. It seems that if I set the distance too short, I "lose" the larger depressions, but if I set it to long, I end up with features that are definitely not depressions.

I tested out some scenarios on a small area, but when I tried to apply the parameters to a larger area, they do not work.

Am I missing something? Is there some sort of guidance for "distance to connector?"

At the suggestion of the Support chatbot, I looked at the parameters in the geoprocessing history. So I did some experimenting in Python.

Setting the value to None reverts to the default
Setting the value to "" reverts to the default
Removing the parameter all together... reverts to the default.

In short, even though the documentation states otherwise, Maximum Distance to Connection Point is not optional in at least ArcGIS Pro 3.6.3.

perhaps it is some preceeding parameter or the version. Below is for SA and Pro 3.7

the parameter is blank, but I left other parameters empty and haven't experimented further. If it is/was a bug/issue I didn't see anything posted on the public facing support site.

Ok. That is definitely different than 3.6.3.

I did "Send to Python" and am able to run it with "None" as a parameter. I'm running an area that is about half the size as I did this morning. That one took 6 hours to run.

ETA... Well, that was the worst result so far. I think I'm going to go back to doing step by step.

progress at least, I thought it might be related to the roads or connections options (which I don't have any to use)
