The history of the development of hydrogeological maps legends is provided, numerous changes in principles of their creation and designing are noted. Electronic database of markers is developed in FSBI “Hydrospetzgeologiya”. It is intended to unify and standardize the design of digital hydrogeological maps set. Main implementation principles, structure and content of electronic database of markers are described. The need to update the database along with the increase of hydrogeological knowledge is noted. The results of electronic database of markers testing on the real projects are provided. The suggestions for further development of hydrogeological mapping are given.
