I am working through the Wetland Identification toolset in ArcHydro and am getting this error on a few tools (screenshot below). I am using .tif's only and have tried a few different versions of the input. My project area is pretty small. I would appreciate any insight into how to resolve this.

 

Thanks!

Hey @AshleyCofrin 

Could you send a screenshot of what the tool itself looks like before you run it, with all the parameters present?

Hey @AshleyCofrin 

I apologize I had not seen this until now, from what I'm finding, there could be an inconsistency between the map coordinate system and the tif coordinate system, are they consistent? I mention this because of a post like this here:

https://gis.stackexchange.com/questions/159780/how-do-i-figure-out-the-length-of-polyline-features-i...

They had the same issue and a spatial reference change had fixed it. Also, is it possible to get a newer or older version of this toolset, you may try a different version to check if it is an issue with the most current.

Hi @AshleyCofrin, were you able to resolve this error? My suggestion is to make sure you're working in a projected coordinate system. We recommend resampling the DEM to 3m as well. Please let us know if you have any additional questions!
