Hi, I'm trying to use the new Python-API with our on-premise system. Our company runs it's own public key infrastructure, so I've configured Portal for ArcGIS with a corresponding certificate. Furthermore, there is a company-wide proxy that we are using. As a first throw, I'd like to connect to ArcGIS Online by doing this: from arcgis.gis import GIS my_gis = GIS() This crashes with: c:\Program Files\ArcGIS\Pro\bin\Python>python.exe "C:\temp\Test.py" Traceback (most recent call last): File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\urllib\request.py", line 1254 , in do_open h.request(req.get_method(), req.selector, req.data, headers) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\http\client.py", line 1106, i n request self._send_request(method, url, body, headers) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\http\client.py", line 1151, i n _send_request self.endheaders(body) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\http\client.py", line 1102, i n endheaders self._send_output(message_body) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\http\client.py", line 934, in _send_output self.send(msg) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\http\client.py", line 877, in send self.connect() File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\http\client.py", line 1252, i n connect super().connect() File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\http\client.py", line 853, in connect self._tunnel() File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\http\client.py", line 832, in _tunnel message.strip())) OSError: Tunnel connection failed: 407 authenticationrequired During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\temp\Test.py", line 7, in <module> my_gis = GIS() File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\site-packages\arcgis\gis.py", line 95, in __init__ verify_cert=self._verify_cert, client_id=self._client_id) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\site-packages\arcgis\_impl\po rtalpy.py", line 160, in __init__ client_id=client_id) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\site-packages\arcgis\_impl\co nnection.py", line 281, in __init__ self.login(username, password, expiration, client_id) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\site-packages\arcgis\_impl\co nnection.py", line 504, in login resp = self.post('', { 'f': 'json' }, add_token=False) # probe portal to fin d auth scheme File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\site-packages\arcgis\_impl\co nnection.py", line 1031, in post resp = opener.open(url, data=encoded_postdata.encode()) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\urllib\request.py", line 466, in open response = self._open(req, data) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\urllib\request.py", line 484, in _open '_open', req) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\urllib\request.py", line 444, in _call_chain result = func(*args) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\urllib\request.py", line 1297 , in https_open context=self._context, check_hostname=self._check_hostname) File "c:\Program Files\ArcGIS\Pro\bin\Python\lib\urllib\request.py", line 1256 , in do_open raise URLError(err) urllib.error.URLError: <urlopen error Tunnel connection failed: 407 authenticati onrequired> Is it related to some proxy issues and if yes, where do I have to configure the proxy? ...

Hi, how can I retrieve the information that the data source of a layer is either a SDE or any other spatial database (Oracle, SQL Server) without using this if the user is not authorized: (IDataset(myLayer)).Workspace.Type‍‍ Background: I have a small command line application written in C# that iterates over the layers of a MXD and gather all data sources that are located within a File Geodatabase. To distinguish between File Geodatabase, SDE and spatial database, I use a combination of (IDataset(myLayer)).Workspace.Type and (IDataset(myLayer)).Category, which works fine. When my application runs under a user who is not authorized to access the layer, (IDataset(myLayer)).Workspace throws a COM-Exception saying that get_workspace() cannot be executed which seems reasonable because the user has no permissions. When opening the MXD with the not authorized user in ArcMap, I see the red exlamation marks indicating the layers that cannot be accessed, but when opening the layer properties, I can see basic information like type (e. g. 'XY Event Source') and path (e. g. 'myDatabaseServer\MyDatabaseInstance'). That's exactly the information I'd like to get in my application, but how can I do this without using (IDataset(myLayer)).Workspace which throws an exception? Thanks! ... View more

Hey, I'm trying to build an application which contains one tiled and one dynamic map service. The tiled map service has the following tile levels: 1:80000 1:40000 1:20000 1:10000 1:5000 1:2500 So, the service's MaxScale property is 2500. For larger scales (e. g. 1:500), I want to use the dynamic map service. Unfortunately, within my JavaScript application I can only zoom in up to 1:2500, further zooming either with the buttons or the mouse wheel is not possible and results in panning the map. Why is this happening? Is it a limitation of the JavaScript API? Regards and thanks in advance PS: I've used the JS APIs 3.17 and 4 - same behaviour. ... View more

Hey, I'm new in developing with the ArcGIS Runtime for WPF, so I think my "problem" is more a question of understanding than development. Within the map, I wann to combine a tiled map service with a dynamic map service. The tiled map service has the following tile levels: 1:50000 1:25000 1:10000 1:5000 So, the tiled map service's max scale property within ArcGIS Server is 1:5000. The dynamic map service contains only one layer with a min scale set to 4999. With this, I want to achive that on a coarse view (small scale) the tiles are used and on a finer level (large scale) the data get rendered dynamically. My WPF application is very simple and viewing each map service individually (either tiled or dynamic) works well. But when combining both, I can only zoom into until the scale level 1:5000. Why is this happening and I this is a feature, how can I reach my desired behaviour? Thanks in advance! ... View more

Hi, I've secured a MapService for a dedicated user within ArcGIS Server 10.1, so a valid login is needed to access the MapServices' data. Is it possible to obtain the user's name within the REST API and if yes, how can this be achieved? Kind regards! ... View more
