</font><font size="3">The NASA ECHO project (</font><a href="http://www.echo.nasa.gov/"><font size="3" color="blue"><u>www.echo.nasa.gov</u></font></a><font size="3">)
is in the process of<br>
providing a search capability, via an ESIP interface (using the Open<br>
Search standard with Geo extension), by point and line.<br>
<br>
The current implementation can be seen at </font><a href="https://api.echo.nasa.gov/echo-esip/"><font size="3" color="blue"><u>https://api.echo.nasa.gov/echo-esip/</u></font></a><font size="3"><br>

The </font><a href="http://www.georss.org/simple"><font size="3" color="blue"><u>http://www.georss.org/simple</u></font></a><font size="3">
specification (which I believe the<br>
geo<br>
extension is based on) provides this support and we would like to<br>
propose<br>
it's addition to the open search geo spec.<br>
<br>
For example,<br>
<br>
Example URL templates:<br>
</font><font size="3" color="blue"><u><br>

<br>
Example requests:<br>
</font><font size="3" color="blue"><u><br>
</u></font><a href="http://example.com/?q=pizza&line=-111.032,42.943,-119.856,43.039&format=rss"><font size="3" color="blue"><u>http://example.com/?q=pizza&line=-111.032,42.943,-119.856,43.039&format=rss</u></font></a><font size="3"><br>

I note that the section of the Geo extension on atom responses has the<br>
element,<br>
<br>
<georss:line>40.73763 -73.9972 40.73519 -73.99167 40.737015 -73.99035<br>
40.73643 -73.98914 40.734640 -73.990431 40.731617 -73.991504</<br>
georss:line><br>
<br>
we propose an additional element for point,<br>
<br>
<georss:point>40.73763 -73.9972</georss:point><br>
<br>
Please let us know if this is proposal is acceptable.</font>_______________________________________________<br>Standards mailing list<br><a href="mailto:Standards@lists.osgeo.org">Standards@lists.osgeo.org</a><br>http://lists.osgeo.org/mailman/listinfo/standards<br></blockquote></div><br></div></body></html>
