Can I be one of your student? Holy smokes this format is so much better than what I am currently learning from! Thank you so much... Hours wasted watching other videos.
Thanks so much for the kind words! This was a good message to start the day with. I'm glad the videos are working for you and thank you for letting me know.

This is an excellent resource, thank you so much for making this video! I am having an issue with the Set Null function. It will not accept a 1 for the "Input false raster or constant value", eventhough the information box specifically states that this option can be any interger. I tried to use the image analyst tool after the spatial analyst tool didn't work, but ran into the same problem. I tried to use several other numbers in this box, but none were accepted. What would you suggest I input here in order to proceed with this tool? Thanks again for this video!
Hi Isabella, Thanks so much for the kind words! That's always a good thing to hear. As for the problem: Hmm. Can you tell me more about how it's behaving? Are you simply unable to type a "1" into the box? If so, then the first thing to try is saving your project, closing down ArcGIS Pro, then restarting it. It could be that some of the code that checks values as you type them into the tool parameters window is misbehaving, and restarting ArcGIS Pro should clear it up. Alternatively, does the tool just crash when you run it? If so, can you let me know what the error message is? And I'm curious if you can run the tool through Python. If so, then it's just the code that runs the tool parameters window that is the problem. Here's some sample Python code to try (and replace the path names and name of your raster as appropriate): #------< Sample Code >--------------------- with arcpy.EnvManager(scratchWorkspace=r"D:\Path_to_Scratch_GDB\ScratchGDB.gdb"): out_raster = arcpy.sa.SetNull( in_conditional_raster="MyRasterToAnalyze", in_false_raster_or_constant=1, where_clause="" ) out_raster.save(r"D:\Path_to_GDB\MyGeodatabase.gdb\MyNewRaster") #-------------------------------------------- Let me know if this helps, Isabella! We can try a Zoom session if you like to figure it out. You can reach me at jeffj@jennessent.com Take care - Jeff
Have you had issues with running this Stream Order tool? I have tried to run this tool several times, and each time it gets stuck on 8% and does not progress. I have let it try to process for several hours, with no progress.
Hello J, My apologies for taking so long to respond! I am sorry to say I have not had this experience, so I am not sure what might be the problem! If you'd like me to take a look, please email me at jeffj@jennessent.com and we can try to figure it out.
I am so sorry to take so long to respond to you on this question! It slipped past me somehow, but I do apologize for my rudeness. If it is not too late to help, then yes, the stream polylines do accurately point downstream. The "StreamToFeature" tool requires the flow direction raster to run, and I suspect it uses this flow direction raster to correctly orient the stream polylines. You can symbolize the streams with arrows by adding an arrowhead-shaped marker symbol to the flowlines.
A strange pause-less, monologue - with no stress, review or clarity which distinguishes fact, instruction and comment. Context setting in impenetrable, but things improve after 4 minutes where he gets specific about steps. No doubt he is an expert but he is not a great teacher, at least not for relative beginners.
Sorry it didn't work for you! Fortunately there are lots of people out there trying to explain this stuff, so hopefully you'll find someone else who suits your learning syle better.
excellent resource, thank you and really really some of the best gis info ive found anywhere, superb, thanks you again ))
Thanks so much Allan! I much appreciate the kind words.

Have you had any luck with this? My situation seem to be the same as yours, where during the stream order processing, it gets stuck at 8%.
What if you symbolized the Stream_to_feature with an arrow? Will the accurately tell the direction the stream in flowing?
My goal is to show the direction the effluent from WWTP is flowing too
