I have a Survey123 survey that has a geopoint for one of its answers.  After the user has selected a location, I then want to use that location to query a polygon layer and populate a subsequent answer with an attribute value from that query.  Is this possible, or beyond the limits of what Survey123 can do? ...

Can Survey123 picklists be updated automatically from data in an Oracle database, which is updated nightly. Has anyone done this and what would be the best way? I suppose once the survey has been published then its picklists are now hosted in the geodatabase, so it might be easier to update them from there, particularly if that geodatabase is also using Oracle. However, wouldn't that then make those picklists out of sync with the source Excel spreadsheet that the survey was originally published from? Hence, would a better solution be to update the Excel spreadsheet then do an automated republish of the survey? If anyone has encountered a similar scenario and can advise on the best approach that'd be appreciated. ... View more

I've set up a geoprocessing service for a client which is an ETL tool. Most of the time it works, but occasionally it fails with an error similar to the following. On each occasion I'm running it for the same area of interest, same map layer to extract from and same format (shape file), ie. all the input parameters are the same each time, yet sometimes it works, sometimes it fails. Error executing tool. MyExtract Job ID: jc9b53901a9dd43d489210ecb9fbe7533 : Traceback (most recent call last): File "\agisdev\arcgisserver\directories\arcgissystem\arcgisinput\GeoMy\ExtractDataTask.GPServer\extracted\v101\geoMy\ExtractData.py", line 522, in zipFolder = clipAndConvert(layers, areaOfInterest, featureFormat, rasterFormat, coordinateSystem) File "\agisdev\arcgisserver\directories\arcgissystem\arcgisinput\GeoMy\ExtractDataTask.GPServer\extracted\v101\geoMy\ExtractData.py", line 368, in clipAndConvert numFeatures = clipFeatures(lyr, aoi, featureFormat, zipFolderPath, scratchFolderPath, convertFeaturesDuringClip, dctColsMaster, dctRowsMaster, dctColsExport, wsExport) File "\agisdev\arcgisserver\directories\arcgissystem\arcgisinput\GeoMy\ExtractDataTask.GPServer\extracted\v101\geoMy\ExtractData.py", line 246, in clipFeatures with arcpy.da.SearchCursor(scratchpath, ["OID@"]) as cursor: RuntimeError: cannot open 'C:\Users\agis-srv\AppData\Local\Temp\geoMy\extractdatatask_gpserver\jc9b53901a9dd43d489210ecb9fbe7533\scratch\scratchfolder\ctLand_Dispositions.shp' Failed to execute (My Extract). Failed to execute (ExtractDataTask). Failed to execute (MyExtract). The error seems to be that it can't find this file:  'C:\Users\agis-srv\AppData\Local\Temp\geoMy\extractdatatask_gpserver\jc9b53901a9dd43d489210ecb9fbe7533\scratch\scratchfolder\ctLand_Dispositions.shp' Why is it creating a scratch folder here? I've looked for this file in \agisdev\arcgisserver\directories\arcgisjobs, where I'd expect it to be but the job folder, jc9b53901a9dd43d489210ecb9fbe7533, doesn't exist here at all, not in any of the subfolders. What's going on? Is it perhaps running out of memory occasionally and having to use the server's temp folder as its scratch workspace? ... View more

I'd like to apply grouping within Web AppBuilder's layer list.  Because the map layers are coming from data hosted in ArcGIS Online (not published from ArcGIS Server), this is normally not available and so it looks like I'll need to customise the layer list widget.  Does anyone have any experience in this?  I'd like to get some idea of the best approach and what would be involved. Some questions I'm considering: Would this work best if the layers were organised into several web maps, one group per web map?  What changes do I need to make to the LayerList widget?  What other widgets would I need to change and how? Any insights or sample code would be most welcome.  Thanks. ... View more
