<p><strong><a href="http://highearthorbit.com/temporary-mapping-solar-decathlon/">Temporary Mapping: Solar Decathlon</a></strong></p> The OpenStreetMap default renderer supports start_date and end_date tags, meaning you can map temporary installations (in this case the 2009 Solar Decathlon on the DC National Mall) and have them automatically appear and disappear at the correct times. <p>Tags: <a href="https://simonwillison.net/tags/andrew-turner">andrew-turner</a>, <a href="https://simonwillison.net/tags/mapping">mapping</a>, <a href="https://simonwillison.net/tags/openstreetmap">openstreetmap</a>, <a href="https://simonwillison.net/tags/solardecathlon">solardecathlon</a>, <a href="https://simonwillison.net/tags/tagging">tagging</a></p>
