results on the map by latitude and longitude

RicardoEufrasio1

Hi guys,

I need to do a search on the map, the search should be made by the latitude and longitude (values ??????that already have the database). I do not know which map to use or is more appropriate.
Can anyone help me

Not clear with what you are asking for. Are you trying to locate the given lat/lon on the map or you like to search for other features that contain the point with the lat/lon?

RicardoEufrasio1

I have the latitude and longitude of the place through this information open the map with location

Like the example (attachment)

require([
  "esri/Map",
  "esri/graphic",
  "esri/symbols/PictureMarkerSymbol",
  "esri/geometry/Point",
  "esri/geometry/webMercatorUtils"
], function(Map, Graphic, PictureMarkerSymbol, Point, webMercatorUtils) {
  var map = new Map({ basemap: "topo" }, "divMap");  // divMap: div element as map container
  var pms = new PictureMarkerSymbol({"angle":0,"xoffset":2,"yoffset":8,"type":"esriPMS","url":"http://static.arcgis.com/images/Symbols/Basic/RedShinyPin.png","contentType":"image/png","width":24,"height":24});
  var point = new Point(lon, lat);  // given lat/lon
  var wmPoint = webMercatorUtils.geographicToWebMercator(point);
  var graphic = new Graphic(wmPoint, pms, null, null);
  map.graphics.add(graphic);
  map.centerAt(wmPoint);
});

Zj_zou thnk you so much to help me, but I could not do...

see my code and the attachment
I pass the latitude and longitude as param by the url like (url of attachments is a example that I'm doing home, the real at job with java)
What is missing?

I am not a java programmer, and cannot understand how you pass the lat/lon from the java bean to the two input controls. In addition, I don't see any code that will use the given lat/lon to zoom the map around. Can you get the lat/lon values from the url or java bean?

TimCollyer

This code will add a graphic based on the url parameters "lat" and "lon"

Note on the example provided above -- the Point is incorrect, passing in lat first and then lon...

It should be --

var point = new Point(lon, lat, map.spatialRefernce);
