I can easily use the GeometryService to project the state plane to lat/long, but need to go in the opposite direction.
I was looking at the REST API for ArcGIS and saw a setting
transformFoward. Is this the setting I need to go in that direction? (http://resources.arcgis.com/en/help/arcgis-rest-api/index.html#//02r3000000pv000000)
What are ways I can do this conversion?
