We are using a product call Epoch Field . The business hasn't fully bought into it yet, but it is an ArcGIS Runtime app and it will run on Windows/Android/iPad. It works disconnected and uses geodatabase syncing. We are still using Server 10.2 but Epoch Field works with newer versions. ... View more

One thing was that I wanted to clarify "the wiki" as there was never a link to it and I wasn't sure what we were talking about. I believe I was agreeing with you and I never mentioned a replacement. Joshua Bixby​ proposed "community edition"  to be part of the official documentation. I'm not exactly sure what Hannah Deindorfer was getting at, but it sounded like the community editions are Geonet, Users Conference, ArcGIS Blog (which I didn't know we could contribute to...) and "the wiki". All of this is spread out across the internet, and if you wanted an official place for that content, why not create a link from the page to a community page that others could follow the same path instead of random geonet posts. There seems to be 2 types of community content that we are talking about 1)     Incorrect Documentation 2)     Additional Examples/Concepts When there is incorrect documenation, it needs to be corrected in a timely manner at the official documentation, not some wiki. Even the smallest error should be fixed, not just the big ones, because the small ones that are easy for someone to figure out are big errors that could be impossible for someone else that is just learning the ESRI dance.  Additionaly Examples/Concepts probably could go in a wiki/geonet post, but probably not wiki.gis.com. As for not knowing esri was behind wiki.gis.com, it's probably because that site has never been the end of a google search for the answer to a problem. I know I have ran across the site a few times before, but it has never answered a problem that I was running into so I just haven't paid it much mind. ... View more

Hannah Deindorfer, Not sure "the wiki" qualifies as an answer to the question. The question was about product documentation. "The wiki" which I am assuming is http://wiki.gis.com/ . I didn't even know this was hosted by ESRI. The wiki seems to be what you would think of a gis wiki and reads more like an encyclopedia about gis in general rather than product documentation of a specific product/tool/api. There is 1 page devoted to python... not 1 page for every arcpy tool. There's not even 1 page on the ArcServer Rest API . .  There's a link, but it's to the 9.3 documentation. If this is an acceptable place for product product documentation and examples, I would suggest putting a link somewhere at the bottom of every page in  ESRI's documentation that would say "See community content". That would bring you to a page... say http://wiki.gis.com/wiki/index.php/ArcGIS_Server/10.3/Add User . If the page was empty, you could create a page and add content. Otherwise, you would see any community content that has already been added. But... I'm not sure that the wiki is the best place for detailed product documentation/examples. ... View more

Since this isn't a class, only a script, you really don't need to put this in a method. How you did it in your original script would work just fine: # archydro variables fill_sinks = os.path.join(rasWs, "fil") flow_dir = os.path.join(rasWs, "fdr") flow_acc = os.path.join(rasWs, "fac") streams = os.path.join(rasWs, "str") stream_seg = os.path.join(rasWs, "strlnk") catchment_grid = os.path.join(rasWs, "cat") catchment_poly = os.path.join(outWs, "Layers","Catchment") drainage_line = os.path.join(outWs, "Layers", "DrainageLine") adj_catch = os.path.join(outWs, "Layers", "AdjointCatchment") If you prefer Path, just replace os.path.join(x,y,z) with str(Path(x,y,z)). Honestly, for what you are doing, I think you might have over-engineered your solution on the 2nd script. The 1st one didn't look too bad. For performance, make sure everything is working in memory like other people have suggested. Only output it to disk when you are through processing it. ... View more

I misread his comment. I thought that he had moved from os.path.join to Path because he was having issues with os.path.join() and arcpy. I now see that he moved *in favor* of Path but that arcpy isn't expecting a Path object but a string. From a python perspective the Path object is an improvement because you are now dealing with a smarter object than a dumb string. The string doesn't know it is a path so you have to call some function to get the file name or directory or to append a subdirectory to the string. From looking at the methods, it looks like you can even create a directory or check if a path exists or not, all from the object itself without having to call another function. As for escape characters, it looks like it doesn't handle them unless you handle them: same as a string or os.path.join(). At the end of the day, I think you're still better off letting python add your slashes and just pass in your directory names in a list and let python make your path for you, whether that be os.path.join(a,b,c,d,e,...) or Path(a,b,c) / d / e / ... # WRONG -- Don't use \t or \a p = Path("dog\turtle\ant") p >> WindowsPath('dog\turtle\x07nt') print(p) >> dog    urtlent # RIGHT p = Path("dog", "turtle", "ant") p >> WindowsPath('dog/turtle/ant') print(p) >> dog\turtle\ant # If you need to append, you are using the / operator, not the literal character '/' p / 'cat' / 'mouse >> WindowsPath('dog/turtle/ant/cat/mouse') ...

As long as you always use os.path.join() and never a slash, you shouldn't have to worry about those pesky paths! ... View more

Yeah.... I'm still on 2.7.x. What's the problem with os.path.join at 3.4? Not having 3.7 installed, but just looking through the documentation and playing around with a 3.x shell online, it seems that os.path.join returns a string object as it always has. It looks like the new pathlib is a way to store paths as objects instead of as strings so instead of having to do os.path.xyz(), you now may be able to do path.xyz. Where I'm confused is how this affects the script. At the end of the day, Peter Wilson is just formatting the path object back to a string. I don't see why os.path.join wouldn't have worked here (not that it's better than using the pathlib). Also it looks path has its own ways to concatenate paths. I went ahead and installed pathlib into 2.7. It looks like you can do this: # constructor p = Path('a', 'b', 'c') print(p) # append paths to end with the "/" p = p / 'd' print(p) print(str(p)) and it will print WindowsPath('a/b/c) WindowsPath('a/b/c/d') a\b\c Either way os.path.join str(Path)      # and "{}".format(Path) should all get you to the same end goal: A string representing a path. ...

There's a link at the bottom right of the page: Feedback on this topic?. I would imagine this would be the appropriate place. Not sure if they ever actually do update the docs until the next release, though. In the past, there's been no way to track the feedback like a bug, and I've never gone back to check if they actually made the changes. ... View more

That's that infinite loop I was talking about. The tool seems to error out a lot. So I loop until it doesn't which is mostly the 1st time, but often it has to loop back a 2nd. It could be from some process trying to make a connection to the database. The "break" after the recalculate extent will break the loop on a successful run and move on to the next feature class. Otherwise, it will disconnect all connected users and loop back around to try again. I could have created a boolean something like... for feature in dataList:      succeeded = False      while succeeded == False:          try:               # recalculate               succeeded = True          except:               # disconnect users And it would accomplish the same thing without the "infinite loop" and "break" ...

Yes, so if going ahead and getting 10.4 is possible, you can use the arcpy tool. I'm using it now. It's kind of slow, but it is getting the work done.... Here's some code I banged out real quick. It will loop over every feature class in a workspace and calculate new extents for them all. def calculate_extents(workspace):     arcpy.env.workspace = workspace     # Get the user name for the workspace     user_name = arcpy.Describe(workspace).connectionProperties.user.lower()     print user_name     # Get a list of all the datasets the user owns.     dataList = arcpy.ListFeatureClasses('{}*'.format(user_name.upper()))     print(len(dataList))        # Next, for feature datasets get all of the datasets and featureclasses     # from the list and add them to the master list.     for dataset in arcpy.ListDatasets('{}*'.format(user_name.upper()), "Feature"):         arcpy.env.workspace = os.path.join(workspace,dataset)         dataList += arcpy.ListFeatureClasses()     # reset the workspace     arcpy.env.workspace = workspace     print('Setting Accept Connections => False')     arcpy.AcceptConnections(workspace, False)     print('Disconnecting Users {}'.format(arcpy.ListUsers(workspace)))     arcpy.DisconnectUser(workspace, "ALL")        for feature in dataList:         while True:             print feature             try:                 extent1 = str(arcpy.Describe(feature).extent)                 arcpy.RecalculateFeatureClassExtent_management(feature)                 extent2 = str(arcpy.Describe(feature).extent)                 updated = 'UPDATED'                 if (extent1 == extent2):                     updated = 'SAME'                 print('{}: {} =>\t{}'.format(updated, extent1,extent2))                 break             except arcgisscripting.ExecuteError:                 print('ERROR -- Attempting to disconnect users')                 arcpy.DisconnectUser(workspace, "ALL")     arcpy.AcceptConnections(workspace, True) I'm using an Oracle database with no datasets. All feature classes are top level, so I'm not sure if this will traverse the datasets. It should, but I didn't have any to test it with. Also, I am filtering only the tables owned by the current user (ex: current_user.table_name). You can get rid of that on lines 11 and 16. I'm not sure how SQL Server handles all that... Also, it seems to error out a lot, so I'm infinitely looping until it succeeds so it could stick forever on a bad feature class, but I haven't had it do that yet. Just be aware if it keeps printing the same feature class over and over, it's stuck... ... View more

Just happened to find in the "What's New in ArcMap 10.4"​ that the Create Database User Tool now creates the log tables when the tool is ran. That certainly simplifies the workflow from an ArcGIS user standpoint. Unfortunately, again, it doesn't help my cause because I need to do all of this from the Oracle side and you still have to come back after running that script and remove the Create table/sequence permissions. I will add that to the list of alternatives. ... View more

Also, fun fact. If this is an Enterprise Geodatabase, it looks like you are just updating the shape column in the GDB_Items table. System tables of a geodatabase stored in Oracle—Help | ArcGIS for Desktop It would be really easy to just update that table... but probably not a supported workflow. At least you know what it is updating and can monitor it. For example, I have a lot of feature classes that don't have extent information. I can find that by select name, sde.st_astext(shape) from gdb_items where shape is null or dbms_lob.compare(sde.st_astext(shape), 'POLYGON EMPTY') = 0 ... View more

The arcpy tool to do this is Recalculate Feature Class Extent​. arcpy.RecalculateFeatureClassExtent_management(feature_class) You will still need exclusive lock on the feature class, but it should do the exact same thing as right clicking on the feature through the GUI. EDIT Sorry, I have a help ticket in for the same thing and this is what they suggested, but I just went to try it and it appears to not be available until 10.4 which should be available any day now... ...
