When running the Drainage Water Management Tool, I keep getting an error – “int() argument must be a string or a number, not ‘NoneType’”. Has anyone else experienced this error? How did you address it?

Do you have any fields that do not overlap with the DEM at all? The script is failing when attempting to determine the approximate # of 1-meter contours that can exist in each field. It doesRead More…

I am getting strange outputs from the “Stream Reach & Catchments” step. Why are additional segments being added to the stream reach?

Image from the user: The original DEM is in UTM15 and the ACPF geodatabase is in UTM14. I changed the projection of the DEM to UTM14 to match. I’ve ran into this when my flow networkRead More…

When I try to delineate streams and catchments, I get error 000732- Input Raster Dataset – in the geoprocessing results. Can you help?

Image from the user: This is the error message I am getting. I am wondering what the issue is. TauDEM should run fine with ArcGIS 10.3.1. Have you restarted your computer since installing TauDEM? I’ve seenRead More…

My DEM is currently in the NAD 83 UTM zone 16 projection which is the correct zone for our area and matches the projection of the data downloaded from the ACPF website. It says the vertical accuracy is 6.24 cm and the horizontal accuracy is 0.6 m. Should I resample my raster to have 7cm z-factor and 1-meter cell size?

Before resampling, take a look at your settings. In ArcMap in the table of contents, right click on the DTM/DEM you are using and select properties. Click on the Source tab and email back with theRead More…

I downloaded LiDAR data for my county, and it is a DTM file. Can I use a DTM instead of DEM?

Sometimes I’ve seen DTMs or digital terrain models represented within ArcGIS as TINs (triangular irregular networks) file structures or terrains (a large version of a TIN introduced a while back to handle big elevation data setsRead More…

Can you help clarify my confusion about the Z factor? I am going through the Pit Fill/Hole Punch process, and I put in .18 since the training manual says 18cm and the raster is in meters. Is that correct?

The z-factor you enter into the Pit Fill / Hole Punch process is the depth of a depression you want to fill prior to main terrain processing. The value given in the document refers to valueRead More…

How can I get the ACPF to work with ArcGIS Desktop 10.4? I am having issues with the DEM Fill process and was hoping the reason for the error was because I am using Desktop 10.4.1.

This error may occur if the workspace and/or scratchWorkspace settings are pointing to bad pathnames. Check the workspace environment settings in ArcCatalog to make sure they are valid. If they are unassigned, you may want toRead More…
