Hi&nbsp;Scott,&nbsp;  
&nbsp;&nbsp;  
&nbsp;Thanks&nbsp;for&nbsp;your&nbsp;post,&nbsp;and&nbsp;welcome&nbsp;to&nbsp;MapSuite&nbsp;world!&nbsp;would&nbsp;you&nbsp;please&nbsp;use&nbsp;Map.CenterAt&nbsp;with&nbsp;following&nbsp;code?&nbsp;  
&nbsp;&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;private&nbsp;void&nbsp;WpfMap\_Loaded(object&nbsp;sender,&nbsp;RoutedEventArgs&nbsp;e)&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map1.MapUnit&nbsp;=&nbsp;GeographyUnit.Meter;&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map1.CurrentExtent&nbsp;=&nbsp;new&nbsp;RectangleShape(-5000000,&nbsp;5000000,&nbsp;5000000,&nbsp;-5000000);&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;GoogleMapsOverlay&nbsp;worldOverlay&nbsp;=&nbsp;new&nbsp;GoogleMapsOverlay();&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map1.CenterAt(new&nbsp;Feature(YourLongitude&nbsp;,YourLatitude));&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map1.Overlays.Add("WMK",&nbsp;worldOverlay);&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map1.Refresh();&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}&nbsp;  
&nbsp;&nbsp;  
&nbsp;Another&nbsp;thing&nbsp;for&nbsp;your&nbsp;information&nbsp;is&nbsp;that&nbsp;Map1.ZoomIntoCenter()&nbsp;and&nbsp;Map1.ZoomOuttoCenter(),&nbsp;could&nbsp;not&nbsp;just&nbsp;centerat&nbsp;but&nbsp;also&nbsp;zoomin&nbsp;or&nbsp;out&nbsp;at&nbsp;same&nbsp;time.&nbsp;  
&nbsp;&nbsp;  
&nbsp;if&nbsp;you&nbsp;have&nbsp;any&nbsp;more&nbsp;question&nbsp;,&nbsp;please&nbsp;feel&nbsp;free&nbsp;to&nbsp;let&nbsp;us&nbsp;know.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Best&nbsp;Regards&nbsp;

Thanks&nbsp;for&nbsp;the&nbsp;reply.&nbsp;&nbsp;I&nbsp;put&nbsp;that&nbsp;in,&nbsp;but&nbsp;when&nbsp;I&nbsp;put&nbsp;the&nbsp;coordinates&nbsp;in&nbsp;for&nbsp;the&nbsp;usa,&nbsp;it&nbsp;is&nbsp;showing&nbsp;africa&nbsp;and&nbsp;south&nbsp;america&nbsp;instead.

Hi&nbsp;Scott,&nbsp;  
&nbsp;&nbsp;  
&nbsp;This&nbsp;should&nbsp;be&nbsp;because&nbsp;the&nbsp;lat&nbsp;and&nbsp;lon&nbsp;themselves&nbsp;don’t&nbsp;belong&nbsp;to&nbsp;google&nbsp;projection,&nbsp;so&nbsp;it&nbsp;needs&nbsp;a&nbsp;projection&nbsp;convertion.&nbsp;If&nbsp;the&nbsp;lat&nbsp;and&nbsp;lon&nbsp;belong&nbsp;to&nbsp;EPSG:4326&nbsp;then&nbsp;would&nbsp;you&nbsp;please&nbsp;try&nbsp;following&nbsp;code:&nbsp;  
&nbsp;&nbsp;  
&nbsp;private&nbsp;void&nbsp;WpfMap\_Loaded(object&nbsp;sender,&nbsp;RoutedEventArgs&nbsp;e)&nbsp;&nbsp;  
&nbsp;{&nbsp;&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ManagedProj4Projection&nbsp;proj&nbsp;=&nbsp;new&nbsp;ManagedProj4Projection();&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;proj.InternalProjectionParametersString&nbsp;=&nbsp;ManagedProj4Projection.GetEpsgParametersString(4326);&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;proj.ExternalProjectionParametersString&nbsp;=&nbsp;ManagedProj4Projection.GetGoogleMapParametersString();&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;proj.Open();&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Vertex&nbsp;projectedShape&nbsp;=&nbsp;proj.ConvertToExternalProjection(yourLongitude,&nbsp;yourLatitude);&nbsp;  
&nbsp;&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map1.MapUnit&nbsp;=&nbsp;GeographyUnit.Meter;&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map1.CurrentExtent&nbsp;=&nbsp;new&nbsp;RectangleShape(-5000000,&nbsp;5000000,&nbsp;5000000,&nbsp;-5000000);&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;GoogleMapsOverlay&nbsp;worldOverlay&nbsp;=&nbsp;new&nbsp;GoogleMapsOverlay();&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map1.CenterAt(new&nbsp;Feature(projectedShape));&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map1.Overlays.Add(“WMK”,&nbsp;worldOverlay);&nbsp;
