Zooming constraints for WMS files

JohnTuohy

Does anyone know if you are limited to the zooming constraints of a WMS file? When using WMS files in mapping services, the user can only zoom in so far, generally to about 1:1,200. I would like to be able to zoom in closer, say 1:600. If this is not possible, does anyone know of any WMS files for the state of NJ that allow you to zoom in closer?

Thanks,
John

Hi John,

Does anyone know if you are limited to the zooming constraints of a WMS file?

If you mean WMS service as in the OpenGIS WMS specification, then "no" there should not be any constraints on zooming for the service as a while.  However, individual layers within a map service might have minscale or maxscale set on them.

If you mean WMS service in the more generic sense of web map services, then it depends on the service.  For example, services that are based on tiled data are often restricted in applications to only show at the scales/levels they have been created for.

When using WMS files in mapping services, the user can only zoom in so far, generally to about 1:1,200. I would like to be able to zoom in closer, say 1:600.

What application are you using to view? 

Maybe you are using a basemap that is based on tile services, and this might be constraining your specific application of viewing the WMS service...
