Hi All - I'm hoping to convert an existing ArcMap Add-in to an ArcGIS Pro Add-in but the tool does quite a bit of Linear Referencing and I can't seem to find an equivalent of the below code, or any other tasks from the linear referencing portion of the tool.  The ArcMap tool allows the user to trace an LRS to define a "project segment" then that segment is located on the LRS and the measures stored in an event table for future use. Any ideas would be great as I haven't been able to find anything dealing with LRS methods. Maybe they're just not available yet?  public static void LRSLocateLine(IFeatureClass InputFC) { try { IRouteLocator rtLocator = LRSSetupLocator(); //create new table name for output to scratch workspace IDataset ds = (IDataset)createWSandFC.fWorkspace; IWorkspaceName wsn = (IWorkspaceName)ds.FullName; ITableName tblname = new TableNameClass(); IDatasetName dsn = (IDatasetName)tblname; dsn.WorkspaceName = wsn; dsn.Name = "events_temp"; try { IDataset tempDS; tempDS = (IDataset)createWSandFC.fWorkspace.OpenTable("events_temp"); tempDS.Delete(); } catch { } //Create RouteLocatorOperations object IRouteLocatorOperations2 routeop = new RouteLocatorOperationsClass(); routeop.RouteLocator = rtLocator; routeop.InputFeatureClass = InputFC; //output event properties IRouteEventProperties2 LMeasProps = new RouteMeasureLinePropertiesClass(); //RouteMeasurePointPropertiesClass(); LMeasProps.AddErrorField = true; LMeasProps.EventRouteIDFieldName = "RTE_NM"; IRouteMeasureLineProperties MPLineProps = (IRouteMeasureLineProperties)LMeasProps; MPLineProps.FromMeasureFieldName = "FromMeas"; MPLineProps.ToMeasureFieldName = "ToMeas"; //Locate the points along the routes double radius = 1; routeop.LocateLineFeatures(radius, LMeasProps, true, dsn, "DEFAULT", null); } catch (System.Exception ex) { MessageBox.Show("Error: " + ex.Message); } }     ...

Hi All - I'm trying to use the "Generate Offline Map" sample and am running into an error that is telling me that the mobile map directory path is not specified. qml: error: Invalid argument Mobile map directory path is not specified. I have tried hard coding the path in the sample to "c:\temp\out.mmpk" just in case my URL variable was not working correctly, but it still is giving me the same result. The only thing I have changed is to give it my own portal item which is a webmap that is available to the public for testing purposes. I'm sure I'm missing something very simple as I'm new to Qt/QML. Any insights would be appreciated. Code is below, but it's almost identical to the original sample.

Hi All - I'm looking to use the sample referenced below to export the contents of a Feature Table to a CSV file in a custom JavaScript application.  JS Bin - Collaborative JavaScript Debugging  It appears that starting at version 3.18 of the JS API, the array generated using FeatureTable.dataStore.data comes back as a JSON object versus an array of attributes and the sample no longer works. I can get at all the attributes using the following, then iterating over each record returned, but it returns all attributes, not just the ones visible in the table and it seems like a overly complicated way to accomplish what I'm trying to do. Object.keys(featTable.dataStore.data[Object.keys(featTable.dataStore.data)[0]].attributes) Has anyone tried to do this in the newer versions of the API? Or know of an easier way to do this? A similar question was asked about a year ago but there were no responses. Feature Table Export 3.18 to CSV  Thank you in advance. ... View more

Hi All, I have what I thought would be a simple editing task, but has turned out to be cumbersome to put it mildly. I have a set of land cover polygons from image data classified at a resolution of 1 foot.  Because the resolution of the reference data are so precise, I'm getting small 1 sqft polygons in the middle of the larger ones.  For example, a 1 sqft impervious surface poly surrounded by 50 sqft of managed turf.  I would like to be able to dissolve these tiny polygons into the bigger ones. I've tried topologies, but that doesn't work correctly because I don't want to lose the resolution of the data that are already there, which happens with high cluster tolearances.  I can delete the polygons of less than a certain area, but then I'm left with tiny gaps that I have to hand edit out, which could potentially be in the hundreds of thousands. Is there any way to programmatically collapse polygons under a certain size, without losing the integrity of the rest of the data?  I'm just trying to clean it up a little bit. Thanks. Pam ...
