I am searching for some ESRI papers that describe what happens when data sources that have an equal area projection (e.g. USA_Contiguous_Albers_Equal_Area_Conic_USGS_version) are transformed/projected to the Web Mercator system and back again via Geometry Services (could be during an overlay with a separate data source, etc.). Some of us neophytes are trying to wrap our brains around what impact this may or may not have on our area estimates. If you can point me to some references I would be very happy. I am checking out ArcGIS Online Geometry Services presently. Thanks.
