# Lambert Conformal Conic

**2**Dear GM,

I prepared a workspace with Lambert Conformal conic and I overlaid a DWG file using the projection Lambert Conformal Conic. The problem is when I rectified to the said projection, my DWG file vertices not showing correct WGS84 coordinates 25 40 55.3N 051 33 45E but in this format 4994330.67630842 4587063.03624404. Is there something I miss in the transformation parameters, if so what should be the parameters?

Your assistance on the above is highly appreciated.

Regards,

Roel

1,8732Tks for the reply, I am using GM ver 13 and the DWG is in local grid. I am experimenting to capture airport mapping elements such as runways and taxiways geometry, somehow when I tried to overlay the dwg and do the rectification using control points and selected "YES" (system to automatically select projection) it fits to the right position but not giving me the correct lat/long for the vertices. Is there a way to set the parameters to transform to wgs84? or a work around for this process, I tried to used Geographic projection, in a way it gives me the correct vertices but the rectified drawing is a little bit skewed (is it normal for GEO projection?).
