Hmmmm   How To: Calculate feature centroids  suggests: "In the following sample, the Data Access Module is used to retrieve the centroid coordinates using the SHAPE@XY token." which I interpret as the polygon centroid. If that is indeed a tuple of many coordinates, how does one get the centroid using the da method? ... View more

Here is something interesting: when I try to extend the point-in-polygon script to polygon-centroid-in-polygon (what administrative boundary is this building located in?), if the input polygon intersects the within polygon (building straddles a county boundary), the result is null:      with arcpy.da.UpdateCursor(update_feature_class, ['SHAPE@XY', update_name]) as update_cursor:         # Iterate through points         for point in update_cursor:             point_count += 1             name_list = []             for name in poly_names:                 comparison_count += 1                 poly = relateDict[name]                 # Check if the current point is within the current polygon                 if point[0].within(poly):  # Returns True or False                     # Add the polygon name to the list                     name_list.append(name)             point[1] = ",".join(name_list)             # Update the cursor with the new value             update_cursor.updateRow(point)     arcpy.AddMessage("Processed {0} Polygon/Polygon or Line comparisons for {1} Polygons and {2} Polygons or Lines".format(comparison_count, poly_count, point_count))‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Richard thanks for the help! I finally had some time to sit down and implement your solution, here's what I got to work with comments, so others can follow. I plan to bake this into a python toolbox and will share.  from time import strftime    print("Script Start: " + strftime("%Y-%m-%d %H:%M:%S")) import arcpy #Feature class to be updated update_feature_class = r'C:\Temp\NEAR\GRSM.gdb\Points_Of_Interest\AED_LOCATIONS' #Feature class containing the attribute we want is nearest road_feature_class = r'C:\Temp\NEAR\GRSM.gdb\Transportation\GRSM_ROADS' arcpy.MakeFeatureLayer_management(update_feature_class,"update_lyr") arcpy.MakeFeatureLayer_management(road_feature_class,"road_lyr") print("Created Layers: " + strftime("%Y-%m-%d %H:%M:%S")) #create a temporary table of near results out_table = r'C:\Temp\NEAR\GRSM.gdb\AED_LOCATIONS_CLOSE' if arcpy.Exists(out_table):   arcpy.Delete_management(out_table)   print("Deleted Near Table: " + strftime("%Y-%m-%d %H:%M:%S")) arcpy.GenerateNearTable_analysis("update_lyr", "road_lyr", out_table)   print("Generated Near Table:" + strftime("%Y-%m-%d %H:%M:%S")) #create a list of attributes from the near feature class where #the second field is the attribute we want to know is the nearest roadsFieldsList = ["OBJECTID","RDNAME"] roadsDict = {r[0]:r[1] for r in arcpy.da.SearchCursor("road_lyr", roadsFieldsList)} matchFieldsList = ["IN_FID", "NEAR_FID"] matchDict = {r[0]:roadsDict[r[1]] for r in arcpy.da.SearchCursor(out_table, matchFieldsList)} #write the nearest attribute to the update feature class #where the second field is the attribute that is being updated with #the name of the nearest feature updateFieldsList = ["OBJECTID", "TEST"] with arcpy.da.UpdateCursor("update_lyr", updateFieldsList) as updateRows:      for updateRow in updateRows:          keyValue = updateRow[0]          # verify that the keyValue is in the Dictionary          if keyValue in matchDict:               updateRow[1] = matchDict[keyValue]               updateRows.updateRow(updateRow)   print("Updated Features: " + strftime("%Y-%m-%d %H:%M:%S")) del roadsDict del matchDict  print("Script Finish: " + strftime("%Y-%m-%d %H:%M:%S")) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Are you running the toolbox as a batch? Your py shows 1 input for feature class, yet your screenshot shows many.  ... View more

Wow....that's a tech support case for sure.In the Pro version, what happens when you move  calc_dr_selection_temp.xlsx to another directory with no spaces or special characters and where your computer login has "Full Control" to the directory? ... View more

For most organizations, excluding anything from security controls is not an option, and not something that had to be done with ArcMap. We have the same AV problem with ArcGIS Server: AV scans of the install directory slows it to a crawl.  ... View more

Would need more details about your workstation: Type of hard drive, processor, ram. I see a lot of difference in Pro "Browse" performance on older or less capable workstations, when we started spec'ing GIS workstation with the Dell Class 40/50 NVMe drives, the "look for stuff" performance increased, but is no where near the performance of Arc Catalog. Your indexing options might help to. But in terms of best advice, your situation seems extreme, and the best advice I have, based on experience (with many successful outcomes), is to call tech support on this one.  ... View more

The option to sort domain values should be that, an option, and not forced on users. There are many situations where forced domain sorting is not only not needed, but violates business logic. For example, Raw, Valid, Certified, Invalid should be presented in the pick list in exactly that order, not sorted alphabetically ascending or descending.  ... View more

I had this issue in the past with ArcMap. As it turned out, there was some sort of automated IT process that kicked everyone off the network share for some sort of AV scan and backup. More details about exactly what is going on on the server overnight is the only way you're going to resolve this case. Is it reproducible when you save it to the local drive and leave it open over night? ... View more
