Is there a case for a general mapping scheme for information that ceases to be valid on a date and could be automatically removed afterwards?<br>

<div>My concern is that if these are permanent features, then people will say "ooh - they'll be the same as last time" and of course they probably won't be the same as last time and we may route people to a wrong place, with possible tragic results.</div>
<div><br>
</div>
<div>I agree that this information should be left in place, but marked , unusable, until specifically activated by authorities, which I agree should be well ahead of time, so long as people know that they will not be usable until a state of emergency is declared.</div>
<div><br>
</div>
<div>Activation should be on a center by centre basis so that authorities will be more likely to ensure the list of centers is accurate and up-to-date.</div>
<div><br>
</div>
<div>I also think that this information should NOT be edited, in any way by anyone other than the authorities. This brings back the old arguments about read only data in OSM.</div>
