Hello everyone, Do you know how to map a field in the Arcpy's AddLocations method, from a GPFeatureRecordSetLayer dataset (FeatureSet from my JavaScript code) ? I created an OD matrix that runs well and that's got for inputs destination GPFeatureRecordSetLayer. It seems to be a problem in the field mapping when I add a location to my destinations, since my location to add are GPFeatureRecordSetLayer and not a Table View. The field mapping goes well when I try it with a table but not with my FeatureSet. Therefore, in output, I don't have the names of my destinations as I wanted to have with the field mapping, but a default name (Location 1, or 2, or 3 ...). Difficult to retrieve the good destination then ! I wish I was enough clear. I can forward my piece of code if you need. Thanks in advance ! ... View more

Hello everybody, I'm trying to make a queryFeatures on a feature layer with StatisticDefinition : I would like to calculate statistics on the field "TOTAL" of my feature layer res, with the features which are within my polygon. Here's my code below : for the moment, I just append a console.log with the result, but the query doesn't work. The array of features stays empty and I don't have any error message. So I guess my query is poorly constructed but I don't see where. Could you help me please ? function (polygon, res) {                                                                                          var queryParams = new Query();                                             queryParams.spatialRelationship = Query.SPATIAL_REL_WITHIN;                                             queryParams.geometry = polygon.geometry ;                                             queryParams.outFields = ["*"];                                              var countSD = new StatisticDefinition();                                             var sumSD = new StatisticDefinition();                                             var avgSD = new StatisticDefinition();                                             queryParams.outStatistics = [countSD, sumSD, avgSD];                                                                                          var sqlExpression = "TOTAL";                                                                                          countSD.statisticType = "count";                                             countSD.onStatisticField = sqlExpression;                                             countSD.outStatisticFieldName = "CountResDial";                                                                                          sumSD.statisticType = "sum";                                             sumSD.onStatisticField = sqlExpression;                                             sumSD.outStatisticFieldName = "SumResDial";                                                                                          avgSD.statisticType = "avg";                                             avgSD.onStatisticField = sqlExpression;                                             avgSD.outStatisticFieldName = "AvgResDial";                                                                                                                                       res.queryFeatures(queryParams,                                                                 function (results){                                                                     console.log(">>>>>>>>>>>>>> r\351sultats de la query : ");                                                                     console.log(results);                                                                 },                                                                 function (err){                                                                     console.log("Impossible r\351cup\351rer le nombre de dialys\351s dans les                                                                     tranches isochrones : ", err);                                                                 }                                             );                                         } ...

Hello everybody, I have two different points with the same exact coordinates however, and when I use a ServiceAreaTask, it creates me just one ServiceAreaPolygon instead of two. The fact is the two points have the same SourceOID since they have the same coordinates. Do you know how to do to have in result two polygons, one for each point ? Thank you very much in advance !

Hello everybody, I have an issue I don't know how to fix. I'm new with the ArcGIS API for JS and with ArcGIS generally. I have a feature layer with points, provided by a Mapserver. I would like to : - select some points on the feature layer (it's ok !) - then save the selection in a variable (an array Graphic[] I guess ? But is it possible ?) - add a new point on a map and store it in the variable with the previous selection (I know how to add a point to a map) - the goal is to have a global selection (existing points and the new point) in a variable that I could reuse to make geotreatments on it (with GPserver and NAserver). I can't publish Featureserver and I can't work on the server. That's why it seems to me complicated. Maybe I'm wrong ? Do you have please any solution ? Thank you in advance ! Clementine. ...
