then "localy<br /> known as xy". Mainly it depends on temperature of water vs temperature<br /> of air.<br /></blockquote><br />unfortunately wikipedia expressly says:<br />"There is no universally accepted definition of a hot spring. For example, one can find the phrase hot spring defined as:"<br /> - a dozen of possible definitions which I won't copy here. (<a href="http://en.wikipedia.org/wiki/Hot_spring#Definitions">http://en.wikipedia.org/wiki/Hot_spring#Definitions</a>)<br /><br />Should that preclude us from mapping them even though they are locally well<br />known as hot springs?<br /><br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> In a cold region a spring with 20°C could be known as hot<br /> spring just because all other springs are much colder. But you would<br /> agree, that no one wants to jump in there and relax ;)<br /></blockquote><br />wanting to relax in one is not really a definition
of a hot spring.<br /><br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> So for this case you have to take care also about temp=*.<br /></blockquote><br />we might think about an optional temperature tag but in my opinion it would be<br />one of the more problematic tags. The temperature may not be exactly known<br />or may be variable. People would start adding it to lakes and oceans:)<br /><br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> But I understand your wish to classify a spring a bit more detailed. I<br /> think it would be better to use additional tags for natural=spring.<br /> Eg. termal=yes or something similar.<br /></blockquote><br />geothermal=yes would be closer. But in a strict sense this would exclude springs<br />with volcanically heated water.<br /><br />Richard<br /><br /><hr /><br />Tagging mailing list<br
