This worked, thanks! I needed to define a small enough fill value to maintain the actual depressions. Cheers, Jeremy

I am trying to delineate the watershed boundaries for depressions. I created a raster from the depression polygons and used Arc's flow direction tool as inputs in the Spatial Analyst watershed tool. However, there are gaps in the watersheds where there intuitively should not be. I've attached an image of an example. The blue represents the depression polygons, the other colours represent the watershed boundaries, it's underlain by flow direction output. I'm not sure why that whole hill slope is not delineated as a part of the middle depression's watershed. This is in the prairies so the relief is pretty subtle (this is using vertical exaggeration of 5 in ArcScene). I'm wondering if these gaps are because the flow direction tool uses a D8 flow routing. Any tips?

Got it to work, those layers had locks on them because I was viewing them in ArcScene. Still looking for a method to smooth the discontinuities at the edge of the filtered and original rasters.

Neither, habitual abbreviation haha. Using the raster calculator. Error 000539: error running expression:rcexec() RuntimeError: Error 010240 Could not save raster data to .... with output format FGDBR

Con(IsNull("setnull"),"focal90","DEMClp") Where setnull is the DEM with the roads given no data, focal90 is the filtered DEM, and DEMClip is the original DEM. The modeling we are doing isn't very traditional hydrological modeling. We are interested in the depressions and so for certain aspects we want to avoid filling. So in order to smooth this discontinuities, would anything happen if I resampled the DEM to the same resolution using the cubic resampling technique?

Thanks for your response, I might be able to make this work. I am having trouble completing the last step, I'm getting errors when I try the Con & IsNull statement. But even without completing it, I can tell there would be sharp elevation jumps between the filtered DEM and the original. I would need another step to smooth those out, as this would be intended for hydrological modeling.

I'm looking for methods to remove/smooth roads and their associated ditches within a LiDAR DEM. I was trying ArcHydro's DEM reconditioning tool to lower the roads and raise the ditches using the road network shapefile but the outputs were not very satisfactory. I don't have the original LiDAR points but I was thinking of extracting the elevation data from each cell (1m 2) to points, removing all points along the roads and ditches and then re-creating the DEM. The previous roads would be re-interpolated from the other points causing them to be smoothed out. Any suggestions would be greatly appreciated.

I should have access to all extensions.

I have acquired DEM data provided in points, hard and soft breaklines from Altalis. It provides them as .gnp, .ghl, and .gsl files. I have followed this thread for the answer AltaLIS DEM: how to load into arcGIS but I am facing the same issue as the last question poses. The breakline data is organized as: I understand what each element is but I am looking for a way to easily format into the 4 fields : Start X Field, Start Y Field, End X Field, End Y Field. Also what is the best way to interpolate a raster surface using both point and line data? Thanks, Jeremy

Did you ever figure a solution to your question? I am currently facing the same issue.

I had python (not sure the version) installed before installing ArcGIS which may have caused issues. I did not modify the ArcGIS installation at all. Jeremy

Solved this thanks to ESRI support. None of the other fixes discussed online helped my case. My issue was due to a bug in Python 2.7.11, this solved it immediately: Start Registry Editor HKEY_LOCAL_MACHINE > SOFTWARE > WOW6432Node > Python > PythonCore > 2.7 Change the name of 2.7 to 2.7-32 Jeremy

Hi Kirsten, I am having the same issues as Olivia, I captured the log: Initializing license...done Parsed command line Creating App... done Processing shell command... Creating New Document... Opening normal template...done... Loading printer information...done... New VBA project...done... Add first mapDone creating New Document done Loading extensions...done Startup complete Any help would be appreciated. I am considering downgrading my laptop to windows 7 or 8 if I can't resolve this soon. Thanks, Jeremy

I have a large amount of polygons representing ponds. I have a stream network shapefile with to and from nodes. I want to know for each pond whether a stream is contributing to it and whether a stream is flowing out of it. Any ideas? Thanks.

Found it! Figured it would have been in the toolbar. Thanks! Jeremy

How would I classify polygons based on whether lines are moving into and/or out of them?
