Hi!
I am trying to query by distance 2 layer (points and lines), I mean I have an initial point and I want to find the closest lines that are within 10 meters.
Afther doing some research in this forum this is my try:
First I query the point layer looking for the source point and I create a graphic symbol:
var resultFeatures = results.features;
symbol = new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([255, 0, 0]), 3);
var point= new esri.Graphic(resultFeatures[0].geometry, symbol);
I create a new query with this parameters:
var query = new Query();
queryTask = new QueryTask(lines_layer.url);
query.geometry = [point.geometry];
query.distance = [10];
query.units = esri.tasks.GeometryService.UNIT_METER;
query.returnGeometry = true;
query.outSpatialReference = new SpatialReference({ wkid: 102100 }); //ETRS89
query.spatialRelationship = Query.SPATIAL_REL_CONTAINS;
I launch the query:
queryTask.execute(query).then(function (qResults) {
// Here goes the code for looping qResults of the lines elements
// that are close than 10 meters from the initial point.
});
Is this the correct approach to launch a query by distance (similar to the one that arcmap haves)?
