comment Seeking web service that returns elevation profile between two points and can process 5000 requests per second
Those are very specific and very demanding numbers without context. If those numbers are real, you're going have to satisfy the ultimate aim a different way, it's trying to buy the moon with a penny. Google's Elevation API limit is 10 requests per second for paying customers, developers.google.com/maps/documentation/elevation/#Limits. Also see api4dev.com

comment How to set feature vertex Z from an intersecting feature's Z?
@Hornbydd, not at present but I can ensure there is if that's necessary or makes it easier.

comment How to set feature vertex Z from an intersecting feature's Z?
@radouxju red line has constant Z, blue line does not. Red line should be read-only and unaltered by the operation.

comment How to interpolate line Z from sparse attribute values
Thank you very much. This provides a solid starting point, and is much better than the rabbit hole I was in, trying to adapt @Tomek's gis.stackexchange.com/a/18655/108 to my circumstance.

comment ArcObjects + comtypes at 10.1 and newer
I removed the 10.1 version specific tag because this same error and fix applies to 10.1, 10.2, and 10.3 (and we don't have a 10.x tag). Also it doesn't need arcgis tag as there aren't any arcobjects without it.

comment How to interpolate line Z from sparse attribute values
Thanks for the pointers @MichaelMiles-Stimson, but generating a surface to interpolate from isn't viable. The known-Z points are too sparse. I know how to get straight to ArcObjects from python, it's the syntax for using the objects themselves that stymies me. I guess it's time I cracked that nut though. ;-)

comment How to interpolate line Z from sparse attribute values
interpolate Z between polyline's vertices (IZ.InterpolateZsBetween ?) looks relevant, if can figure out how to use from python, and span lines.

comment Enabling public viewers and private editors of feature service on ArcGIS Online For Organizations?
If the feature service is not open to public at all, then the issue I describe doesn't apply. However if the FS is displayed in a public map, any public map, and at the same time the FS is edit-enabled for anyone at all, then anonymous users can create/edit/delete data in the FS with minimal effort. In the case where the FS is never displayed in any fashion outside the authorized group, the data can still be edited anonymously, but the effort to discover the fs-ID in order to get to it is non-trivial. The door is changed from concealed to hidden, but it isn't locked.

Can't fire someone who doesn't work for you. I added a feature to Ben's edit-restricted group from a personal public account, essentially it's an anonymous edit. I didn't need or use his webmap to do it.

This isn't effective as the edit/non-edit permissions are controlled at the group level. Anybody can bypass your groups and go straight to the edit-enabled feature service. In effect they create their own group that has whatever permissions they like. The underlying feature service is either open or closed, without any gradation between. See Ben Mearn's answer and commentary.

I don't see how role-based accounts would change or protect things meaningfully. A scripted scheduled task to republish as another completely read-only layer might be workable. Ensuring reliability might take some doing. Please let me know how Esri responds, here or personally.

comment How to check if a file is a valid raster image?
Belatedly realised I picked a bad example. For comparing "does result have same data as input" the best solution is one which does test for content validity. It wouldn't be safe to delete the original file just because the compressed file can be read without error. Correct solution for the first example is gis.stackexchange.com/questions/111954/…

comment Enabling public viewers and private editors of feature service on ArcGIS Online For Organizations?
Found a way in. Look at "Buildings" feature service. There's a new record with NAME=Fake Building made by matt, to the north east off Old Paper Mill road. i.imgur.com/hi03EqU.png. Is this feature service supposed to locked from public editing?

I'm interested in following through on this, please ping me at matt.wilkie@gov.yk.ca. I confirm that attempting to view item details of the FS link above fails with 404 not found, ditto for "Buildings" and "Parking" layers from with the app. I'd like to go over the details of your configuration as compared to mine (screenshot etc.). Thanks!

comment Unable to rotate Marker Line Symbols
In that case you might be able to use the "flip all" check box to reverse flow direction depiction. For ArcInfo we had a "stream flipper" AML which would use a DEM to put the coordinate pairs in each line in the order of stream flow (uplsope to downslope). There's probably something similar for arcpy.
