Snap Pour Point tool: Why is it hanging at 100%?

JAMIESOMMA — Fri, 17 Jan 2020 18:56:04 GMT

When I'm running Snap Pour Points tool for a set of 15 points on a flow accumulation raster, it's hanging after getting to 100% on the progress bar for the "Snapping pour points..." step. All 15 points were generated from certain portions of the stream line generated from the sane flow accumulation. I'm needing to do this because though 13 points are well located, 2 of them are just off the stream accumulation raster cells, so I'm needing to snap them over a bit to get proper watershed analysis. The Snap Pour Point tool is consistently hanging whether running with 15 points or 1 point. I'm using a Snap Distance of essentially the width of 2 - 10m raster pixels (20 meters or 62 feet).

After cancelling the hung process from the status window, an unhandled crash exception occurs and I used that tool to send the crash dump data and referenced this discussion thread title for context. The Errors that I see presented in the status window before it crashes are as follows:

ERROR 999999: Error executing function.
The table was not found. [VAT_KeyPointsSnapRaster]

Original post was under ArcMap v10.6.1. I've upgraded to 10.7.1 but still seeing the same issue.

Hi JAMIE SOMMA,

Sorry to hear that you are having issues with the Snap Pour Point tool. Could you please share the datasets that are causing this issue and I can investigate further.

For Snap Pour Point tool please provide,
1) Input pour point (Raster or feature)

2) Input accumulation raster (Raster)

3) Snap distance

4) Pour point field

Additionally, are you using any environment settings? If so, could you mention what these are.

Best Regards,

Hello,

I've run into this problem as well. The solution that worked for me was to make sure the point dataset and the raster image are projected to the same coordinate system.

Hope this helps someone going forward,
