Calculate resolution based on map extent

prashantk — Tue, 23 Jul 2013 10:05:55 GMT

Hi all,

I want to set MinimumResolution for graphics layer.

I am trying to calculate the resolution value from map extent so user can zoom to particular location and set the value for graphics layer.

Any help would be appreciated.

Regards,
Prashant

The resolution is the size of one pixel in map coordinates.
so something like: var res = extent.Width/MyMap.Width;

The current map resoluton is also exposed as MyMap.Resolution.

Hi,

Thanks for your quick reply.It works for me.For different zoom level i am getting resolution value.Now i can easliy set this value to minimum / maximum resolution for graphics layer to set visibility.

Thanks once again,
Prashant
