JavaScript API - how to get the map units?

TomSellsted

Greetings,

I have been looking for a method or property that will give me the units (IE: meters, feet, degrees) of the map being displayed. I have looked at the map.spatialReference.toJson(), but it only returns the WKID and not the units. Any suggestions of how to get this property? It would certainly be ideal to have a property map.mapUnits or a method map.getMapUnits(). Thanks!

Regards,

Tom

Hi Tom - a very similar question was asked recently: Re: How to get linear distance units of a layer?

In short, the SpatialReference class does not contain a property for linear units.

This is good news - the client side Geometry Engine looks great too:

Robert,

That is excellent news! I will have to change my settings interface after the next release, but it will be worth it! Thanks very much!
