Maps are graphical representations of geographical data. They have been produced for as long as humanity has been exploring the Earth, and now there are maps of astronomical bodies outside the Earth as well. Originally done on paper or parchment, maps are now also done electronically (as with just about every other medium), and there are now online maps such as Google Maps and Open Street Map which can be scrolled, zoomed, and otherwise manipulated.
