Hello,<br><br>I've written an implementation for the Azavea Raster Grid format (<a href="https://github.com/azavea/geotrellis/wiki/ARG-Specification" target="_blank">ARG spec</a>) that we use in <a href="https://github.com/azavea/geotrellis" target="_blank">GeoTrellis</a>.<br>
<br>I created a ticked for this feature: <a href="http://trac.osgeo.org/gdal/ticket/4591" target="_blank">http://trac.osgeo.org/gdal/ticket/4591</a><br>
<br>This is the first driver that I've contributed, so if you have the
time, I would appreciate any feedback you have about the driver
implementation.<br><br>Thanks,<br>David
