<DIV>Hi Wendell</DIV>
<DIV> </DIV>
<DIV>My belief is that you need something like Mapserver to serve the images. It would render a seamless "stitched" view on the fly, depending on the area you had zoomed into. OL just acts as the thin client viewer.</DIV>

<DIV>Cheers,</DIV>

<DIV style="COLOR: #000000">I have several GeoTIFF images and each shows up just fine<BR>(by itself, using gdal2tile to break them up).<BR><BR>How do I use OpenLayers to show a patchwork of maps? That<BR>is, the left edge of one is the right edge of the other; the<BR>bottom of one is the top of yet another, etc. In fact, I<BR>have lots of these that form a mosaic of a given area.<BR><BR>Should I use gdalxxx to put them together to form one (very<BR>large) map and then use gdal2tile to break it up, or craft<BR>OpenLayers.Layer.TMS.prototype.getURL to determine which<BR>patch to get? If the latter, how do I reference everything<BR>in lat/lon degrees instead of pixels?<BR><BR>Is there an example of this in the openlayers example<BR>section? I looked, but since I'm new to OpenLayers, I'm not<BR>sure what I was seeing, or what I should be looking for.<BR><BR>Thanks,<BR><BR>Wendell<BR><BR>_______________________________________________<BR>Users mailing list<BR>Users@openlayers.org<BR><A href="http://openlayers.org/mailman/listinfo/users">http://openlayers.org/mailman/listinfo/users</A><BR><BR><BR><BR><BR></DIV><br><br><table bgcolor=white style="color:black"><tr><td><br>------------------------------------------------------------------<br>
