topic Can the projection of the Map control can be changed dynamically in the code behind? in ArcGIS API for Silverlight Questions https://community.esri.com/t5/arcgis-api-for-silverlight-questions/can-the-projection-of-the-map-control-can-be/m-p/24783#M608 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>To use ESRI provided map service (WGS 84), all our map services are been projected onto the WGS84 coordinate system and added into the map control during initialization phase. However, to generate a relatively accurate length (e.g., 500 feet) segment on our map, I want to change the map projection into State Plane. Is there any way that I can do this?</SPAN><BR /><BR /><SPAN>Thanks in advance!</SPAN><BR /><BR /><SPAN>Wei</SPAN></BODY></HTML> Tue, 31 Aug 2010 17:35:39 GMT weiliang 2010-08-31T17:35:39Z Can the projection of the Map control can be changed dynamically in the code behind? https://community.esri.com/t5/arcgis-api-for-silverlight-questions/can-the-projection-of-the-map-control-can-be/m-p/24783#M608 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>To use ESRI provided map service (WGS 84), all our map services are been projected onto the WGS84 coordinate system and added into the map control during initialization phase.
