In order to overlay vector data can be in ArcView, the data must have the same datum and projection. To equate the projections we can use the ArcView Projection Utility.
Open ArcView Projection Utility2. Browse and locate the data vector to be projected (could be more than one)> Click Next
Select Coordinate System Type, for example, for Indonesia select: Geodetic> Name: GCS_WGS_1984> Click Next> Finish.
Furthermore, the data can be in the overlay. To overlay vector and satellite images, adjust image and vector projection as well. Just a suggestion, so as not to be confused with the projection system only select one type of projection for your data, such as GCS WGS 1984, so that data can always be in the overlay each time it takes
