What has been there yesterday may no longer be valid today.  I discovered the situation shown above of a 30 km\/h speed indication in a small German city some day on my way to work. The digit &#8220;3&#8221; wore out because it was right under the <a href=\"https:\/\/www.geonatives.org\/?p=120\">track<\/a> of the left wheels of a typical vehicle whereas the &#8220;0&#8221; was in the middle of the <a href=\"https:\/\/www.geonatives.org\/?p=120\">lane<\/a> and, thus, hardly touched by the tires.<\/p>\n\n\n\n<p>I&#8217;m glad I took the picture that day because just a few days later, the &#8220;3&#8221; got repainted by the municipality.<\/p>\n\n\n\n<p>But how do you want to keep track of these &#8220;oddities&#8221; in your data lake?
