ArcGis Flex viewer 2.2 Zoom

CristiDelgado — Wed, 16 Feb 2011 20:54:26 GMT

The viewer does not allow you to zoom in very close. Is it possible to change this? I understand that it is limited to how the tiles were cached. However, when I zoom into Bing maps at bing.com/maps, I can get much closer.
Thanks

Thanks for pointing this out. After looking at it closer, it seems the problem in this case is that the metadata that Bing returns is announcing that they have 19 levels. When in fact on their own website they are using 20 levels. We'll follow up with Microsoft about this.

Could you let me know when this is resolved via this thread or the Blog? The viewer is useless to my operations if we cannot zoom in any closer.
Thanks,
Cristi

We have the same problem.
Can I also be updated?

I'd like to add...incase it can help somebody, is our work around for the moment... We use the Wold_relief service as the starting and main background for our data...when you zoom in close on that service, it just goes to an all white background so we can still see our features zoomed in. If we need to see roads or the imagery, we have to zoom out a little.

Just thought I'd throw that out there.

I'll try to remember to update this thread as well as making sure it get's included in the "What's New" in both the documentation as well as the blog post we post when we release a new version.

does anyone have an update on this? I need to zoom in closer too and am not sure of the best solution.

Microsoft has acknowledged this (the metadata not returning the correct available levels) as a bug. I don't have an estimate yet on when they will fix it.

I am having the same problem and am in need of an immediate fix. Is there a work around for this issue? I do not need a basemap to be shown, I just need to be able to zoom into the vector data added to the project. Are there other basemaps available that can be used? If I create my own image service with high resolution aerials we had flown, will this work? Also, does anyone know if the extralods widget found in the following forum will work?

Yes, if you create your own service with more detailed info, then there is no problem. This thread is about showing Bing at sub 1K scales.

Also, does anyone know if the extralods widget found in the following forum will work?

As of version 2.2, this is supported out-of-the-box and thus no need for that widget using the <lods> tag. See under Map at http://help.arcgis.com/en/webapps/flexviewer/help/index.html#mainconfig.htm

Just put this into your Config.xml file under your widgets..this will give you 1 more level of zoom detail

@Gerald,

Thanks.

Your post of the LOD was very useful.

Bjorn,
Still no time estimate from Microsoft to fix the bug so we get all 20 levels of zoom from Bing?
Thanks,
Cristi

BjornSvensson — Mon, 11 Apr 2011 20:20:29 GMT

@Christi, no word from Microsoft, but in version 2.3 of the Flex API we will have support for all levels of Bing anyways.

Re: ArcGis Flex viewer 2.2 Zoom

CristiDelgado — Tue, 26 Apr 2011 16:40:22 GMT

Hi, I downloaded the new Flex 2.3 viewer which states that there are two more scale levels and I still cannot zoom any closer. ?!

Re: ArcGis Flex viewer 2.2 Zoom

BjornSvensson — Tue, 26 Apr 2011 16:43:03 GMT

@christi - Are you using the Bing basemaps, or the default config which has the ArcGIS Online basemaps? It's only the bing services that has the extra details.

See Bing example at http://help.arcgis.com/en/webapps/flexviewer/live/index.html?config=apps/config-bing.xml which goes down to 1:282 scale.

Bjorn,
Can you point me in the right direction to get the Bing base maps in 2.3.1? I really need that extra zoom level.

Thanks,
Greg

Re: ArcGis Flex viewer 2.2 Zoom

BjornSvensson — Thu, 05 May 2011 15:28:24 GMT

To see the detailed Bing levels, add Bing as the first basemap.

See "Bing application" sample on http://help.arcgis.com/en/webapps/flexviewer/samples.html

Re: ArcGis Flex viewer 2.2 Zoom

GregoryPierce — Thu, 05 May 2011 16:03:01 GMT

It looks like the config file link for the bing application doesn't work. I removed a dash towards the end and it pulled up. Just an FYI. Thanks for your help.

I just downloaded 2.3.1 and seem to have lost 2 levels of extent on the default base maps. This viewer stops at 1:4513 and the older one went to 1:1128. The cache still shows those two extents but I cant seem to zoom that far. Any help would be appreciated.
