I am trying to add shapefiles (lines) to the mxd file with the ESRI World Street Map as basemap. I get an error "Geographic Coordinate Systems Warning" The following data sources use a geographic coordinate system that is different from the one used by the data frame you are adding the data into"
I noticed that I get this error only when I add a line shape file and not when I add point shape file. Besides, both the line and point shape file have the same projections and coordinate systems when I checked it through the ESRI catalog.
Would appreciate any thoughts as to why I keep getting this error message.
