Hi,  
I have a doubt, we can set projection to Map features by two ways.

1. we can set by Layer.  
layer.FeatureSource.Projection = \_proj;

2. we can set by feature.  
imAirports.InternalFeatures.Add(\_proj.ConvertToExternalProjection(fpointfrom));

My question is both ways will work correctly plot all features with proper projection. or we can set by features only?

Thanks,  
Riyaz

Hi Riyaz,

The both way can works, in fact way one is automatic reproject the features on the fly.
