Ce n’est pas le monde (This is not the world) by John Krygier, a geographer from Ohio Wesleyan University and Denis Wood, an artist and a cartographer.
What are maps? What they do? Which one to refer as the correct one? Map can be portrayal of what is existing, a representation of the same or an image. This is how different people defines maps to be and there are more definitions or terms used for maps from one person to another, and the maps they would make even though it would be of the same place it differs. If not these, what actually them a map is? It can be considered as a proposition which does not always indicated what is there but it could be an abstract of whatever information that has to be conveyed about a particular place or a thing. This way we would have plenty of maps of a same place, which one do we refer as the correct one? Maps can vary from cartographer to cartographer. For an example, two cartographer who are neighbors sharing a common piece of land, will make different map where each one will show the piece of land in their premises. Map does not have to be showing a place and information overlapped on it, it could be an abstract. Map can only have a collage of numbers or a map can be a satellite imagery and yet both are correct as it is only a proposition.
