Hi, I am trying to populate a field for lines that are separated by another point feature class. However, some lines shares common vertex coordinates but not with the point feature class. So the number of shared vertices can range anywhere from 2 - 5 lines. I have a script that generates a unique ID based on a random number, but what I am struggling with is how to go about it. I am also trying to keep it as light as possible without needing to create another feature class. Here is what I have thus far. (also, I keep getting the error message 'dictionary changed size during iteration' error message) import arcpy import random import time start_time = 'Process start time: {}'.format(time.strftime('%I:%M:%S')) print (start_time) #arcpy.env.overwriteOutput = True # Input parameters #InputFolder = r'*' spointFc = r'*' LineFc = r'*' # Describe input features ##desc = arcpy.Describe(LineFc) ##Geometry = desc.shapeType # Create separate folder and database #- Create folder if folder does not #- exist. ##Folder_Name = 'Storage Folder' ##Folder = os.path.join(Folder_Name, InputFolder) ## ##Created_Folder = '' ##for root, directory, folders in os.walk(InputFolder): ## for folder in folders: ## if folder == Folder_Name: ## Created_Folder = os.path.join(folder, root) ## else: ## Created_Folder = os.mkdir(Folder_Location) #- Create geodatabase if geodatabase does #- not exist. ##Created_GDB_Name = 'DataHolding.gdb' ##Created_GDB = os.path.join(Created_GDB_Name, Created_Folder) ## ##Created_Geodatabase = '' ##for root, directory, folders in os.walk(Created_Folder): ## for folder in folders: ## if folder == Created_GDB_Name: ## Created_Geodatabase = os.path.join(folder, root) ## else: ## Created_Geodatabase = arcpy.CreateFileGDB_management(Created_Folder, Created_GDB_Name) # Set newly created file geodatabase # as the new workspace. ##arcpy.env.workspace = Created_Geodatabase # Gather fields for searching through # and updating each feature class.

I have been thinking about this for quite some time, but I thought it would be very helpful if there was an application created specifically for scheduling either scripts, processes, field calculations, or updates to feature layers published either as hosted or from a server, where the user(s) can schedule tasks similar to windows task scheduler but as an Esri Application. I have noticed that there are a lot of people who need to understand programming or have certain permissions to utilize windows task scheduler. So I thought it would be a massive help if an online Esri application designed specifically to set scheduled tasks is something that could be created. ... View more

I think that it would be a huge help if attribute rules could be instilled with the option for a check box to update using 'Real Time'. Meaning that if that option is checked, regardless of the feature being published or not, that the feature would update based on real time. It seems rather strange that only a few triggers exist currently for attribute rules (Insert, Update, Delete), but having the option of selecting real time would be extremely helpful. ... View more

Hi, I have noticed that, in the web maps, that users can create custom fields based on arcade expressions which shows as temporary field(s). However, those fields are only shown in the web map and cannot be used for setting a filter on the layer. It would be very helpful if a temporary field can be added that updates attributes in real time and be able to filter based on that attribute value. Another option would also be for hosted feature services to have the ability to have fields created, based on an arcade expression, and used in the web map with full functionality. If this already exists and I simply overlooked it, please let me know. Otherwise, I hope that this is something that can be implemented because it can be used for a multitude of the projects that I work on.  ... View more

Hi, I have a custom solution, designed using WAB in ArcGIS Online, which utilizes the Query Widget. I noticed that there isn't an option in the widget settings that allows for a predefined spatial relation in the widget. For what I am trying to do, it would be really helpful if a spatial relation could be set for when the users utilize the widget. ... View more
