<div>Hi Experts,<br>
I need a little advice on how to do lots of aerial image GeoTiffs quickly. I have a large region with many GeoTiffs covering 9 UTM zones. Typically I would put together a map file with layers per utm zone and use shapefile index to point at the GeoTiffs. I
know that declaring the extent per layer is important when you have a lot of layers. The GeoTiffs are RGB, internally tiled, and jpeg compressed. They are also about 20-30MB in size.<br>
<br>
</div>
My question is, has anyone done any testing between doing this via shapefile index vs GDAL .vrt files? Which would perform faster?<br>
</div>
My current setup is using Mapserver behind nginx in fastcgi mode.<br>
</div>
Thanks for any help on this.<br>
