Geocode Address then Buffer

[jaykapalczynski]

I am trying to Geocode an Address then Buffer that address....from there I want to use that buffered graphic for further queries...

I can get the Geocode to work but stuck on getting the Buffer code to create the buffered graphic of which I need to use its geometry to run further queries..

Am I way off here?

// GEOCODER START===========================================================================================

var x = "";

var y = "";

  var geocoder = new Geocoder({

   arcgisGeocoder: {

  placeholder: "4010 West Broad St, RIchmond, Virginia"

   },

   autoComplete: true,

   map: app.map,

  }, dom.byId("search"));

  geocoder.startup();

    geocoder.on("select", showLocation);

    geocoder.on("clear", removeSpotlight);

        function showLocation(evt) {

          //app.map.graphics.clear();

          var point = evt.result.feature.geometry;

  x = point.x

  y = point.y

          var symbol = new SimpleMarkerSymbol().setStyle(

            SimpleMarkerSymbol.STYLE_circle).setColor(

            new Color([255,0,0,0.5])

          );

          var graphic = new Graphic(point, symbol);

          app.map.graphics.add(graphic);

// ATTAMPT TO BUFFER THE RETURNED LOCATION

  var paramsGC = new BufferParameters();

  paramsGC.geometries  = graphic;

  paramsGC.distances = [ .5 ];

  //paramsGC.bufferSpatialReference = new SpatialReference({wkid: 26917});

  paramsGC.outSpatialReference = app.map.spatialReference;

  paramsGC.unit = GeometryService.UNIT_STATUTE_MILE;

        // geometry service that will be used to perform the buffer

        var geometryServiceGC = new GeometryService("https://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer");

  geometryServiceGC.buffer(paramsGC);

        geometryServiceGC.on("buffer-complete", function(result){

          app.map.graphics.clear();

          // draw the buffer geometry on the map as a map graphic

I tried to use the variable Point as well but nothing

var point = evt.result.feature.geometry;

var paramsGC = new BufferParameters();

  paramsGC.geometries  = point;

  paramsGC.distances = [ .5 ];

[jaykapalczynski]

Think I got it... forgot the  [ ]

paramsGC.geometries  = [ point ];

This is the code...

1. Geocoder
2. Then Draw Buffer around Gocoded Result
3. Then Query 1 Features and return their respective Geometry

// GEOCODER START =================================================================

var x = "";

var y = "";

  var geocoder = new Geocoder({

   arcgisGeocoder: {

  placeholder: "Dallas, Texas"

   },

   autoComplete: true,

   map: app.map,

  }, dom.byId("search"));

  geocoder.startup();

    geocoder.on("select", showLocation);

    geocoder.on("clear", removeSpotlight);

        function showLocation(evt) {

          //app.map.graphics.clear();

          var point = evt.result.feature.geometry;

          var pointGC = evt.result.feature.geometry;

  x = point.x

  y = point.y

          var symbol = new SimpleMarkerSymbol().setStyle(

            SimpleMarkerSymbol.STYLE_circle).setColor(

            new Color([255,0,0,0.5])

          );

          var graphic = new Graphic(point, symbol);

          app.map.graphics.add(graphic);

          //app.map.infoWindow.setTitle("Search Result");

          //app.map.infoWindow.setContent(evt.result.name);

          //app.map.infoWindow.show(evt.result.feature.geometry);

        var symbol_historicArchitectureGC = new SimpleFillSymbol(

            "solid",

            new SimpleLineSymbol("solid", new Color([0,76,153]), 2),

            new Color([0,128,255,0.5])

          );

        flVAFWIS_historicArchitecture.setSelectionSymbol(symbol_historicArchitectureGC);

        // Add the Feature Layer To Map

        app.map.addLayer(flVAFWIS_historicArchitecture);

  var paramsGC = new BufferParameters();

  paramsGC.geometries  = [ pointGC ];

  paramsGC.distances = [ .5 ];

  //paramsGC.bufferSpatialReference = new SpatialReference({wkid: 26917});

  paramsGC.outSpatialReference = app.map.spatialReference;

  paramsGC.unit = GeometryService.UNIT_STATUTE_MILE;

        // geometry service that will be used to perform the buffer

        var geometryServiceGC = new GeometryService("https://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer");

  geometryServiceGC.buffer(paramsGC);

        geometryServiceGC.on("buffer-complete", function(result){

          // draw the buffer geometry on the map as a map graphic

          var symbol22 = new SimpleFillSymbol(

            SimpleFillSymbol.STYLE_NULL,

            new SimpleLineSymbol(

              SimpleLineSymbol.STYLE_SOLID,

              new Color([247,5,38]),

              2

            ),new Color([255,255,0,0.25])

          );

          var bufferGeometryGC = result.geometries[0]

          var graphicGC = new Graphic(bufferGeometryGC, symbol22);

          app.map.graphics.add(graphicGC);

          var query_historicArchitectureGC = new Query();

          query_historicArchitectureGC.geometry = bufferGeometryGC;

    // Select the Points within the Buffer and show them

          flVAFWIS_historicArchitecture.selectFeatures(query_historicArchitectureGC, FeatureLayer.SELECTION_NEW, function(results){

          });

    });

} // End function showLocation(evt) {

Jay,

put the following outside of your showLocation function:

var point;

and then remove the var in front of point inside your showLocation function, so that it looks like this:

point = evt.result.feature.geometry;

now it should be global and ready to be used in your BufferParameters.
