Hi JK,<div><br></div><div>The googles layers actually have different zoom levels, sometimes going to hybrid goes to 21, physical goes to 22 and such. Look up the maxzoom for the terrain layer, that might fix your problem.<br>

<b>Subject:</b> [OpenLayers-Users] Google Terrian map does not align with geometry</span></p>

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">My application draws many geometries (basically, polygons, each representing captured aerial images). All of my geometries align correctly with Google Street, Satellite, Hybrid maps, but not correctly with Google Terrian map.
</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">While in Google Terrian map, when I zoom in to say zoom levels more than 10, the mis-alignment starts to show up, and another issue also starts showing up, the rectangle of my geometry becomes movable. All of these are simply wrong. These
will render the application unreliable which means useless for our users.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Can anyone share some thoughts about these behaviors? How to fix them?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">How Reliable is OpenLayers? I’m seeing many un-reliability and inconsistence.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks.</p>
