comment Best practice to perform raster map algebra in open source web GIS?
"Is there a reasonable way to ..." is a really wordy phrase (where, e.g., "How to ..." works just fine) to put in a question title, so if you can think of a better way to state your question than what I had suggested please do so. Also, I consider the word "software" to include programming APIs and libraries, such as GDAL, so by that interpretation, your reversion of my edit was probably unnecessary. However, do what you wish if you think it clarifies your question.

Very useful (and extensive) list of implementations, thanks!

I attempted to clarify your question title -- am I correct that it now reflects the meat of the issue you are asking about?

comment How do updateParameters and updateMessages Interact in a Python Toolbox?
Also I was testing using a script tool rather than a Python toolbox. Maybe there is a difference there, although my gut feeling is there shouldn't be.

Maybe you are using a different version than I am. I'm using 10.2.2, you?

You don't? Google already did it for you, you just use their API.

comment Get Coded Value Domains from a Oracle geodatabase using PLSQL
This will not work with SDE 10.x+ geodatabases due to changes in the geodatabase schema: blogs.esri.com/esri/arcgis/2010/03/15/… -- also link-only answers are not well received on this site because they tend to become useless when the link breaks.

Yep that works, see update.

I believe the filter will prevent you from selecting a disallowed feature type interactively, but if you enter one manually, it will set an error message saying that it's not allowed. If you need to allow the user to continue then you might be able to use updateMessages to replace the error with a warning. I'm not positive on this though.

comment How to determine the optimal raster resolution when interpolating a surface from points?
Well it also depends on why you are interpolating in the first place, and what you need to do with the resulting surface. But "optimally", in terms of not losing information, you would want to use a resolution of no more than 1m (as points within this distance of each other may be considered coincident). But in terms of providing a "representative surface", if your average (not minimum) point spacing is, say 100m, use that for your resolution. You will be binning multiple samples into the same cell quite often, but depending on your use case that may or may not be desirable.

What is the positional accuracy of the data? I suspect this is the most important factor.

comment Using ArcGIS and QGIS together in multi-user editing environment?
@mike That should not cause any problems because they are separate transactions and because one is an add and the other is a delete there is no chance for conflict.

comment Using ArcGIS and QGIS together in multi-user editing environment?
@MichaelMiles-Stimson I understand your concerns, but I would just be clear that the same warnings apply to QGIS. If you did DB traces on edits with both clients my guess would be that the queries/transactions as seen by the DBMS would be essentially identical. I mainly just disagree with the recommendation to only use QGIS here as if it is somehow safer to use than ArcGIS (in non-versioned editing mode). The question is about using ArcGIS and QGIS together and I feel that the recommendation to not use ArcGIS at all warrants further examination.

comment Using ArcGIS and QGIS together in multi-user editing environment?
Non-versioned editing with ArcGIS is probably exactly the same as with QGIS as far as the database and its consistency are concerned. I would suggest revising this answer to include the information @PolyGeo provided, as if you're going to be doing non-versioned editing at all, you might as well be able to do it with whichever client application you prefer.

comment How to replicate QGIS vector smoothing effect in ArcGIS for Desktop?
I would be surprised if ArcGIS Pro didn't have this feature, as it's WPF-based, which does support anti-aliasing.

comment How to replicate QGIS vector smoothing effect in ArcGIS for Desktop?
Just FYI, the effect you are trying to replicate here isn't quite working because the browser is downscaling both the images because they are too wide for the Stack Exchange site layout. You have to right-click and "view image" to see them in their full resolution. I have edited your question to make the images link to themselves so that you only need to click on them to view them.
