Hi Andrea,
Not to worry, I’m hoping to upgrade soon anyway; it’s not a big issue and yes I
did also remove the property file (not sure about the sample image).
Yeah, ongoing saga with me and my raster files as you may remember from a few
years ago. I’m not against using other formats but I just never seem to be able
to get my image processing right. Did you use GDAL for your translation or was
it something else?
Cheers,
Paul

Hi,
That’s interesting, well we are using 2.9.3 and it definitely recreated the
shapefiles when the server loaded. I’ll leave it to the experts to decide if
that is expected or wanted behaviour but it seems to be possible to replicate
on that version as far as I can tell.
Mind, 2.9.x is not supported anymore. Try 2.11, if that one does not do it
anymore, then problem solved (the changes in 2.11 cannot be backported to 2.10,
too extensive, sorry).
Perhaps just try it and see if it does it for you, you just delete the
shapefile for an image mosaic layer and hit restart, it will either work or not.
Just removing the shapefile won't work. You also have to remove the other
mosaic support files, the property one and the sample image.
I will double check my facts regarding the ECW usage but the main reason we are
looking to switch is disk space. The ECW files are much smaller and have
overlays inside the files whilst my GeoTiffs were bigger and I think some (if
not all) didn’t even have pyramids yet. This means the file size would be
increased further once I’d resolved that issue and ICT were looking for us to
reduce the file sizes.
I was doing some training months ago and we took an ECW, translated to a
Geotiff with JPEG compression, 85% quality, YCBCR color interpretation, full
overviews and the result was... smaller :-)
No visible quality difference. We did not do performance testing, but at the
naked eye performance seemed to be the same.
Cheers
Andrea
