Tiled layer and zoom issue.

SanajyJadhav

Hi,

I am really stuck on this issue.

I have added ESRI World street map as base map and on top of it I am adding our own data.The online service tiles end at a scale of 4513.However, I want to zoom further down up to the scale of 282. To do this, I have added LODs to my map.

For some reason, my map is allowing me to zoom in up to the scale of 1128.I do not know where this figure comes from.My data has layer whose min. scale is 282 and max scale is 0.Despite adding LODs, map is not allowing me to zoom in after the scale of 1128.

Can anybody help me on this issue please? I would appreciate it.

-Sanjay.

Yeah,

I have been thanking those guys from time to time.:)

That is unfortunate about support. I think it'd be cool if you gave them a thank you in the SL forum (that is, if you haven't already

SanajyJadhav

The other thing I'll add is that these are user forums and are not official way of getting Esri support.

Yeah, I am fully aware of that.But unfortunately ESRI India does not provide us technical support on SDK issues, that's why we have to rely on these forums. And my experience is that Silverlight API development team members are doing great work.They have helped me out in so many issues that I would say my previous project was completed because of them only. Especially, Jennifer,Morten,Domnique,Ali have been of great help.

Thanks,
Sanjay.

You're welcome. The other thing I'll add is that these are user forums and are not official way of getting Esri support. Lots of Esri folks hang out in these forums, but they are not technically obligated to do so.

Thanks Derek for getting back to me on this responsiveness issue. I never thought you were going to discuss it with me.Appreciate it.

I'll definitely twit you if I am stuck on anything.

Glad you got it worked out. Not sure why restarting the SOM fixed it but...I guess that's how things go sometimes.

Regarding responsiveness...I don't have a good excuse/reason. We've been busy but I'll spare you the details. You can always get my attention via twitter...

Derek,

I got it resolved.I restarted the SOM process and it got fixed.Now I can zoom into the scale of 141 without any problem. God knows what was wrong with it.I had cleared the REST cache but still there was the problem.

Thanks for your time Derek, I appreciate it.

And one more thing I would like to mention, this JS API forum seems quite slow and unresponsive as compared to Silverlight API forum.I do not know the reason why but I feel that way. On Silverlight forum, there are so many API team members helping out users.

Thanks,
Sanjay.

Have you tried using the pattern shown in this sample: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/map_switch_layer_on_zoom.html

Is your service with the large scales available publicly?

SanajyJadhav

Derek,

Thanks for the reply.

Here is code that defines LODs.

//Define level of displays
    var LAlods = [{

},
{
"level": 17,
"resolution": 0.074645535444977125,
"scale": 282.124294
}
];

And here I am setting LODs in the map.

  map = new esri.Map("map", {
      extent: initialExtent,
      logo:false,
      lods:LAlods
    });

I appreciate your help.

Please post the code showing how you're manually defining your LODs.
