Geographic envelope of the Moon and the identification of Moon landscapes with the use of the axiomatic method

open access: yesOpen Astronomy, 2017
Three consequent concepts that build up the algorithm of the identification of modern landscapes on the Moon surface are suggested. They are anaglyphonosphere axiomatic and landscape concepts obtained with the use of the axiomatic method.
