Zoom to geoprocessor result

DavidChevrier — Tue, 18 Aug 2015 14:16:14 GMT

Hi,

This should be pretty easy, but I've tried a bunch of stuff and cant get it to work. How do I zoom to the newly outputted feature layer created by a geoprocessing service I create. Here is the code for I use to create it. I've tried the commented out method for setting the map's extent with the test1 and test2 variables, but it doesn't work.

Thanks,

-dave

function gpJobComplete(jobinfo) {

//get the result map service layer and add to map

gp.getResultImageLayer(jobinfo.jobId, null, null, function (layer) {

layer.setOpacity(0.7);

layer.id = "Created Mammal Data";

map.addLayers([layer]);

});

// var zoomLayer = map.getLayer('Created Mammal Data');

// var test1 = webMercatorUtils.geographicToWebMercator(zoomLayer.fullExtent);

// var test2 = zoomLayer.fullExtent;

// map.setExtent(test1, true);

map.on("layers-add-result", function (evtObj) {

domUtils.show(dom.byId('legendWrapper'));

if (!legend) {

var layerInfo = array.map(evtObj.layers, function (layer, index) {

return {

layer: layer.layer,

title: layer.layer.name

};

});

legend = new Legend({

map: map,

layerInfos: layerInfo

}, "legendWrapper");

legend.startup();

}

});

}

You could do something like this:

   function zoomToData (featureLayer) {
      // Zoom to the collective extent of the data
      var multipoint = new Multipoint(map.spatialReference);
      arrayUtils.forEach(featureLayer.graphics, function (graphic) {
        var geometry = graphic.geometry;
        if (geometry) {
          multipoint.addPoint({
            x: geometry.x,
            y: geometry.y
          });
        }
      });

      if (multipoint.points.length > 0) {
        map.setExtent(multipoint.getExtent().expand(1.25), true);
      }
    }

Hmm.... this is failing with a weird "typeerror: d is not a function". My guess is this is because I don't have a required statement. This is just part of a big project, so here are the ones I have. Am I missing one?

"esri/geometry/Multipoint" is missing

Re: Zoom to geoprocessor result

DavidChevrier — Tue, 18 Aug 2015 18:59:02 GMT

Ah, I was forgetting that, but it still didn't work. But I know why, it isn't a feature layer that is being returned, rather a ArcGISDynamicMayServiceLayer. Any idea how to zoom to that?

Tim,

How did you determine he was missing the "esri/geometry/Multipoint" requirement?

Re: Zoom to geoprocessor result

TimWitt2 — Wed, 19 Aug 2015 15:49:14 GMT

Terry,

The code that I posted needed "esri/geometry/Multipoint"

var multipoint = new Multipoint(map.spatialReference);

and once he posted his 2nd post I went through the list and looked if he has it already included in his current code.

Yes. But I've decided to take the results and turn them into a featurelayer instead. So I'm able to zoom using

var graphicsExtent = graphicsUtils.graphicsExtent(features);

map.setExtent(graphicsExtent);
