MapView Resolution Units Conversion

LukeCatania — Wed, 04 Apr 2012 16:39:03 GMT

My maps are in Geographic WGS84. When I use the getResolution method on the mapview, what units is the resolution in? Radians? Degrees?

How do I convert them to meters? I tried

AngularUnit.convertUnits(mapView.getResolution(), Unit.create(AngularUnit.Code.RADIAN), Unit.create(LinearUnit.Code.METER))));

but received an error:

com.esri.core.geometry.GeometryException: invalid_call

Luke,

I'm not sure, but

http://services.arcgisonline.com/ArcGIS/SDK/REST/export.html

dpi
Description: The device resolution of the exported image (dots per inch). If the dpi is not specified, an image with a default DPI of 96 will be exported.

Example: dpi=200

We tried to discuss here about it.
