Tiling Errors on WebRAVE 18030002 TauDEM has tiling issues

[joewheaton]

These errors were reported by @nbouwes on this TauDEM 18030002 project, which was for the Kern and based on LiDAR inputs.

It is the LiDAR TauDEM and has Tiling Errors on only the TWI and Flow Accumulation the tiling broke on:

Thanks Nick,
Yes the WebRAVE view of the LiDAR based projects is failing on a bunch of TauDEM and a couple VBET projects. This is a known issue and one we have to make some headway on soon. If you download the project I suspect it is working fine. We have to get zoom tiling levels figured out for reach-scale projects and a strategy for these big LiDAR datasets. Matt anything to add or is this one any different?

@MattReimer suggested:

I'd have to dig into it to find out why it's happening.

For rasters I've seen it fail on invalid values, big datasets that max out the tilerizer's memory. There should be logs.

Ok, I did some really cursory looking into it and this is a weird raster. It's 2.2Gb and it's got some really weird asymptotic values in it. None of that is definitive but I'm putting this here just to remind myself later.

Unfortunately I need to sideline this fix for now so I can get the new warehouse online. We can revisit if this is still a problem in the new system.

All sounds good... not a high priority, just queuing up so it is addressed as part of Warehouse V2 refactor later.
