If this is a one-off issue, perhaps the topological editing tools could be useful. In Pro, go to Edit > Modify Features > Align features. (see reference here). You can select the segments to align, set the snapping tolerance as needed, and even identify a point location (the node in your image) to align the segments to.  ... View more

Thanks, Josh! Quick follow-up question, I'm still wrapping my head around the difference between arcgis and arcpy. Is arcgis used to access the ArcGIS API, while arcpy is pulling from your local instance of Pro? Also, good to know about limitations of modifying a python env in Pro, saves me time knowing it's not really possible. Thanks again!  Jo   ... View more

Hello @jcarlson, I'm trying to do the same thing as OP. Do you have any tips on successfully creating an environment where arcpy and geopandas work together? I am using a cloned python environment in ArcGIS Pro. I am getting a failed message when trying to conda-forge install geopandas. I also am worried about the same thing occurring when trying to install shapely.. Many thanks!  ... View more

Hi David, thanks so much. I'll give that a go. Reclass will probably quicken the raster to polygon process! ... View more

Thanks Jayanta - I followed these steps but now the second, appended layer (33N) nearly replaced the original (32N) layer that was projected in step 2. The total is still around 4.4million rather than the expected 8-9million features. Are there also size limits in file geodatabases as well?  ... View more

Hi @DanPatterson  thank you! I had also tried reversing the order but was still getting the same result. The suggestion from Joe Borgione to run Add Join worked for my use case. ... View more

Hi @JoeBorgione , thanks for the suggestion - this is what I needed. Sometimes the simpler option is the best one! ... View more

Hello @tt1 , I'm encountering a similar problem. Did you happen to solve it?  Thanks! ... View more

I am also having this issue in 2.6, and had the same issue as OP. Seems to be that you have to re-create the clone every time you update. ... View more

Hi Joshua, thank you. this makes sense and was helpful. Unfortunately I am now getting an OSerror again, that a file doesn't exist. It seems as though the for fname loop is not being iterated at all, as it is not printing anything. I think it could have to do with the fname variable again, but I can't  tell what aspect of it is. My updated code is as follows:  import arcpy, os, sys from arcpy import env arcpy.env.overwriteOutput = True # Set the workspace directory - make sure it's the copied gdb and not the original, in case you mess up arcpy.env.workspace = r"mygdb_.gdb" # Get the list of the zonal stats tables to process tables = arcpy.ListTables() print(tables) # iterate through the tables in the gdb and update field names with the file names for table in tables: print("processing: " + table) expression = str(table) # populates field # iterate through field names in the table and alter field name for fname in [f.name for f in arcpy.ListFields(table, wild_card="*AFG_proj_zonalst", field_type="ALL") if not f.required]:    print(fname)    arcpy.AlterField_management(table, fname, fname+'"'+expression+'"')    print(fname)     with arcpy.da.UpdateCursor(table, [fname]) as uc:       for row in uc:       uc.updateRow([str(table)])     del row, uc and the error message:  [prints list of files] processing: NTL_QN_202001_AFG_proj_zonalst processing: NTL_QN_202001_AFG_zonalst processing: NTL_QN_202001_proj_zonalst processing: NTL_QN_202001_zonalst processing: NTL_201912_AFG_proj_zonalst processing: NTL_201911_AFG_proj_zonalst processing: NTL_201910_AFG_proj_zonalst processing: NTL_201909_AFG_proj_zonalst processing: NTL_201908_AFG_proj_zonalst processing: NTL_201907_AFG_proj_zonalst processing: NTL_201906_AFG_proj_zonalst processing: NTL_201905_AFG_proj_zonalst processing: NTL_201904_AFG_proj_zonalst processing: NTL_201903_AFG_proj_zonalst processing: NTL_201902_AFG_proj_zonalst processing: NTL_201901_AFG_proj_zonalst ---------------------------------------------------------------------------OSError Traceback (most recent call last)<ipython-input-5-7d2495ac6c17> in <module> 17 expression = str(table) # populates field 18 # iterate through field names in the table and alter field name ---> 19 for fname in [f.name for f in arcpy.ListFields(table, wild_card="*AFG_proj_zonalst", field_type="ALL") if not f.required]: 20 print(fname) 21 arcpy.AlterField_management(table, fname, fname+'"'+expression+'"')C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\__init__.py in ListFields(dataset, wild_card, field_type) 1131 1132 * String: Only field types of String are returned.""" -> 1133 return gp.listFields(dataset, wild_card, field_type) 1134 1135 @_gptooldoc(None, [[["FeatureLayer", "Table", "TableView", "Dataset", "FeatureDataset"], "", "", ""]])C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\geoprocessing\_base.py in listFields(self, *args) 346 from arcpy.arcobjects.arcobjectconversion import convertArcObjectToPythonObject 347 return convertArcObjectToPythonObject( --> 348 self._gp.ListFields(*gp_fixargs(args, True))) 349 def listIndexes(self, *args): 350 """GP function ListIndexes""" OSError: "NTL_201901_AFG_proj_zonalst" does not exist ...

Hi Joshua, thanks for your quick response - It was indeed an issue with calling the list of tables instead of a single table. After updating the line, I no longer have the OSError, but am now having the following error: "NameError: name 'f' is not defined". It was my understanding that 'f' is just the iterator variable for the list of fieldnames, and does not need to be defined before being called. Sorry for the really simple questions, I'm new to arcpy so it's probably another beginner error. ... View more
