Suppose you have several layers of data that you want to add to ArcMap. All the data has a common geographic coordinate system. One of the layers is in an Equidistant Conic projection. You would like to view all the layers in this projection. All of the following methods below would set the data frame to the Equidistant Conic projection, except one. Which one?
Set the data frame to Equidistant Conic, then add all the layers.
Add the layer in the Equidistant Conic projection to the empty data frame, then add the remaining layers.
Add the layers in a geographic coordinate system first, then add the projected layer.
Add all the layers to the data frame, then apply the Equidistant Conic projection to the data frame.
