comment Check if feature class has at least 1 shape that overlaps raster
@Vince I hadn't at the time. It appears to work and be quite fast (less than 5 seconds to check a nearly worldwide feature class with around 150,000 records against about 60 rasters). My apologies for the poor question. I really should have done more research and tried more first. I was frustrated and tired at the time, and I have been fighting these sorts of problems with ArcObjects for literally a couple months.

comment Spatial join versus classical join
I think your answer misses the mark. You don't have to JOIN on exact matches for non-spatial JOINs either. I've written many queries of the form SELECT * FROM x JOIN y ON x.id < y.id because I was looking to compare all rows without duplicating the combinations. You can go further: SELECT * FROM x JOIN y ON x.timestamp BETWEEN y.start_timestamp AND y.end_timestamp. There are lots of ways to do non-exact JOINs that have nothing to do with spatial.

comment Setting “REAL” work/scratch workspace in ESRI/ERDAS etc
Apologies. I must have missed it. Maybe just make it more prominent for people who aren't paying as much attention like me?

Note that this global change will affect all applications that use this standard location.

comment How many layers are too many layers in ArcMap?
Your first paragraph just sounds like typical day to day ArcMap usage to me, maybe made worse by the Citrix set up. It is not exactly known for its performance, in my experience. Locking up is a frequent occurrence.

comment Do I need to explicitly release extension licenses?
Thanks! That sounds like a pretty definitive, "Yes, I need to check them in explicitly," to me. I wasn't able to find that documentation. Btw, your link has an extra %20http:// that makes it not directly clickable.

comment Troubles Updating Values of Selected Features with PyQGIS
My guess about what's happening: lyr.changeAttributeValue(fid,12,"0") updates the value, but the object in f remains unchanged. So lyr.updateFeature(f) reverts it back to the original value. Is that right?

Have you checked the data for invalid polygons?

comment List of GDAL raster file extensions
Your code is more or less fine. You're largely constrained by the GDAL API itself, so unless you plan to write wrapper code that follows the norms of the language a bit more (which for an application that would have to be maintained, I probably would), this is what you have to do. Even with the wrapper code, you're going to do something similar to this in the guts of it, anyway. The only thing I'd really advise changing would be to split the extension string on space, so you have a list of extensions. That would require testing for edge cases like None, though.

I agree that saying they're meaningless is going a bit far. What I would say is that they are a convention only, and that anyone and any software is free to violate the conventions.
