</div>One example of my long-term goals (I'll leave them to my Grandchildren ;) ) is to be able to take say an layer containing prehistoric monumental and settlement features and look at the extent to which the Romans developments respected these.<br>

In the fullness of time and with plenty of support, I'd like to see layers to cover all periods of history covered.<br></blockquote><div>Me too, but I would not expect the main OSM page to do this - we will have to have a separate 'OSM-history' map I think. </div>

This requires a renderer / display set up that allows the use to select what features you want and filter out those you don't.<br>
<div class="im"><br></div>What I can see of OSM the editing tools are quite good, though they could/should be enhanced if my goals reach 'critical mass'. The rendrering engine will require significant enhancement to support selectable layers unless I have missed something.<br>
</blockquote><div>I will make a mock up rendering tonight to see if it is the sort of thing you are thinking of - I was just thinking of adding a layer switcher to my existing history map (<a href="http://maps3.org.uk/tiles/historic.html">http://maps3.org.uk/tiles/historic.html</a>) to allow you to select prehistoric/roman/modern features etc.</div>
