Hi all,<br><br>I am new to OpenLayers and I'm confused about GPS coordinate and Spherical Mercator projection. <br><br>OpenLayers says "The projection used by Google Maps is the spherical mercator." at link <a href="http://docs.openlayers.org/library/spherical_mercator.html">http://docs.openlayers.org/library/spherical_mercator.html</a>. The documentation of Google Maps says "Google Maps uses the formulæ for the spherical Mercator, but the coordinates of features on Google Maps are the GPS coordinates based on the WGS 84 datum.". <br>
<br>I have GPS coordinate data in pure decimal GPS coordinate format for example 25.124167 in order to place the feature on the map. And I will use Google Maps layer with OpenLayers. Is any convertion required? Does OpenLayers implement in the background?<br>
<br>Can you please explain this subjects?<br><br>Thanks a lot for your helps and clarifications,<br>Yasemin<br>
