Maps are limited for a region but for some criteria they also change

The biggest disadvantages of maps come from maps which are badly made in one way or another:
*.Maps are never perfect. The smaller-scale the map, the more detail from the real world is missing, evenif it has no actual errors. Features are simplified (this is called generalisation) and averaged out.
*.Flat maps always involve distortion. It’s not possible to project the curved surface of theEarth onto a flat sheet/screen with perfect accuracy, andwhile there are some projections which faithfully reproduce either areas or directions, the maps in most common use (Mercator variants) badly distort areas away from the equator.
*.Maps always omit information. To make maps readable for one type of information, another kind of information must be left out, otherwise themap becomes an unusable mess. Most labels on maps obscure something which could otherwise have been shown there.
*.Maps don’t show time, but hardly ever say whatspecific pointin time they are supposedto represent. For instance the map of Europe on mywall right nowshows Crimea as part of Ukraine, but in fact it was annexed by Russia in 2014. The map doesn’t state what date it shows.
