NavLunar Gives the Moon a Coordinate System
An interactive lunar map uses the NASA/USGS Lunar Grid Reference System to assign linkable addresses across the Moon.
Field notes
NavLunar organizes lunar locations around the NASA/USGS Lunar Grid Reference System, presenting cells, named features, mission sites, and coordinate conversions as linkable map objects. The page describes 25-kilometre cells with precision down to one metre and gives concrete examples for Tranquility Base and Chang’e 4. Its terminator view uses solar ephemeris calculations to show where daylight currently falls, while the data credits identify NASA, USGS, IAU, and related public planetary datasets.
