i am working with various layers that have the following coordinate system and projection:


  • Coordinate system: GCS_CAPE
  • Projection: Transverse_Mercator


How can I add a base map that is aligned with them? The base maps have the following features :


  • Coordinate system: WGS 84
  • Projection: WGS 1984 Web Mercator (auxiliary sphere)


Base maps cannot be projected.


When I try to specify a transformation for the data frame (its coordinate system is Transverse Mercator) to enable the alignment 'on-the-fly' of the base map when I add it to the map, I obtain the following message: "A datum transformation cannot be found. The data may draw with an offset". So I cannot choose any transformation,


Please help !
