Is it possible to zoom some scale which is not available in BaseMap ?

mohannainar1

Hi,

I am using custom basemap(contains 4 scales 1:500000,1:200000,1:100000,1:50000) in my javscript application and doing attribute query in operational layer and got the results. The result(featureset) extent is falling 1 : 20000 scale , is it possible to zoom 1:20000 ? . I guess it is not possible , want to know if there are any workaround for this issue .

Mohan,

You add some more scale like 25000, 15000, 10000, 7500, 5000, 2500 using the info i provided above and WAB when it zooms will use the closest scale available when zooming.

It seens if you call view.scale 2 times it forces to go to that scale, so I'm using this code as a workaround:

view<SPAN class="punctuation token">.</SPAN>scale <SPAN class="operator token">=</SPAN> <SPAN class="number token">10000</SPAN>
view<SPAN class="punctuation token">.</SPAN>scale <SPAN class="operator token">=</SPAN> <SPAN class="number token">10000</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Mohan,

You have a tag on this question of "arcgis webapp builder" yet you have this question in the JS API space... So is this a WAB question?

Sorry for the confusion . Yes I want to do it WAB .

Will try and let you know the feedback.

Mohan,

In WAB you can specify more LODs in the app:

Robert,

My scenario is

1.Created basemap with 4 scales only (1:500000,1:200000,1:100000,1:50000).

2.Through query operation(custom tool or widget) i got the feature set (dynamically) . The feature set will have the extent and that extent is not falling into the base map scale. .For example I may get scale for the featureset 1:2500 or 1:7000 or 1:8000 .

3.In that case Can i zoom to 1:2500 or 1:7000 or 1:8000 ? . Is it possible to view the basemap details in 1:2500 or 1:7000 or 1:8000 .

4. The featureset scale 1:2500 or 1:7000 or 1:8000 is not constant , this will vary depends on the user query.
