ArcGIS API for JavaScript 4.0 - Problem viewing ArcGISTiledLayer

JamieKelly — Fri, 08 Jan 2016 13:54:31 GMT

Here is my code:

<!DOCTYPE html>

<html>

<head>

<title>Get started with MapView - Create a 2D map</title></p>

<style>

html, body {

padding: 0;

margin: 0;

}

</style>

require([

"esri/Map",

"esri/views/MapView",

"esri/layers/ArcGISTiledLayer",

"dojo/domReady!"

], function(Map, MapView, ArcGISTiledLayer){

var tiled = new ArcGISTiledLayer({

url: "http://map.stjohns.ca/mapsrv/rest/services/Mapcentre/STJ_MC_Ortho_2013_MapService/MapServer",

resampling: false

});

var map = new Map({

//basemap: "streets",

layers: [tiled]

});

var view = new MapView({

container: "viewDiv", //reference to the scene div created in step 5

map: map, //reference to the map object created before the scene

zoom: 4, //sets the zoom level based on level of detail (LOD)

center: [-52.75, 47.6] //sets the center point of view in lon/lat

});

</script>

</head>

<body>

</body>

</html>

It is almost directly from the ESRI sample pages. I'm trying to show our local tiled map service layer in a map view. I've set resampling to false because I was getting 404: file not found errors when tiles were being retrieved. I've set a center lon/lat close to my area of interest. I cannot see any tiles from the map service. What am I doing wrong?

Thanks,

Jamie Kelly

Jamie,

You have some issue with your tiled map service. The issue can be seen here using the ArcGIS Online Map Viewer:

I saw the same thing at ArcGIS online, however, here is basically the same code for the javascript API V3.15 that works just fine.

<!DOCTYPE html>

<html>

<head>

<title>Simple Map</title>

<style>

html, body, #map {

height: 100%;

width: 100%;

margin: 0;

padding: 0;

}

body {

background-color: #FFF;

overflow: hidden;

font-family: "Trebuchet MS";

}

</style>

var map;

require(["esri/map", "dojo/domReady!"], function(Map) {

map = new Map("map",{

zoom: 1

});

var ortho2013 = new esri.layers.ArcGISTiledMapServiceLayer("http://map.stjohns.ca/mapsrv/rest/services/Mapcentre/STJ_MC_Ortho_2013_MapService/MapServer", {

visible:true,

id: "ortho2013"

});

map.addLayer(ortho2013);

});

</script>

</head>

<body>

</body>

</html>

So are there some special changes needed to the published web service to work with the new API? Would this issue be related to the Known Limitations?

Thanks for your help,

Jamie

Jamie,

I was trying to find a thread I remember seeing about using a cached service with a non web-mercator project in the 4.0 api but right now I can not find it. I did test your service using 3.15 and saw that it worked correctly with the 3.x api. But the fact that it does not work with AGOL map viewer and my tiled map services and esris do leads me to believe that there is a deeper issue with your service.

I was able to view the tiled service in arcGIS online by adding a layer as "An ArcGIS Server Web Service".

I've looked at the source code for this map, but it serves me no help. I could not find the code showing me how the Tile service was added to the map. From what I can see in the API, there is no type of layer for "An ArcGIS Server Web Service".

Jamie,

I think this is a case for tech support.
