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.
