Can somebody tell me the meaning of that map 3D 0007B786 C5E2 C1AA

Be a bit more specific when asking something,
anyway I think you're watching to VAG Edc15 suite...
The description anyway is:

Map type - Address - Y Axis ID - X Axis ID (or XID - YID, don't remember :) )

You need to provide the file youa re looking at when asking questions about maps and especially when showing a specific map...
