As a developer implementing a queryFeatures workflow for a feature layer that has not been added to the view, if a query would end up exceeding the max number of features allowed by the service, is it the responsibility of the developer to make subsequent queryFeatures calls to capture all features?  That is, does the developer has to write the logic to to look at the "exceededTransferLimit" return value, and make subsquent calls implementing paging?  Is there any way to have the SDK to this for you with one function call in the code resulting in however many network calls to get the full list of features?  I know that's how it works when you're adding a feature layer to a map - you only have to write map.add(featureLayer) and the SDK just makes however many necessary calls it takes to get the features back.  Was hoping this is how queryFeatures works as well, but my preliminary testing seems to indicate that is not the case.  Here is a codepen that shows what I'm talking about: https://codepen.io/jaysgregory/pen/dyeKYYy   ...

I'm trying to easily create a data expression that adds an attribute to each feature in a data set, but I'm getting stuck on how to add an attribute to an existing feature without creating a feature from scratch, including all pre-existing attributes.   I get an execution error: "key not found - attributes.' In short, do I have to create a brand new feature and manually reference each attribute I need, or is there an easy way to simply add an attribute to an existing feature.    var portal = Portal('https://www.arcgis.com/'); var layer = FeatureSetByPortalItem(portal, itemid) var features=[]; for (var i in layer) { var newvalue = some logic here i['attributes']['newattribute'] = newvalue Push(features,i) } return { geometryType:'', features:features }     ...

I'm curious if arcpy methods that take as input a CSV or text file can accept a file-like object instead, so I don't have to write to disk before invoking.   For example, if I have a dataframe df:   import pandas as pd from io import StringIO import arcpy s_buff = StringIO() df.to_csv(s_buff) arcpy.management.BearingDistanceToLine(s_buff, "memory\\output", "x", 'y', 'd', bearing_field="b")   This generates an error: Error in executing tool.  s_buff.read(), s_buff.seek(0) also generates errors.  I know I could write to a temporary file, but I'd rather not.   ...

Does it exist - because I could not find GeoEventSimulator.exe anywhere in /opt/arcgis/server. If it doesn't exist, how can I get it?     ... View more
