Hi Jody,

I did as you suggested, using the single image mosaic, but it gives an error 
when uploading all the images in esps:5013 (image1). So I created two single 
image mosaic one for the islands in espsg: 5015 and the other for espsg: 5014 
and then I created the layer group. I don´t know if it is the best solution, 
but it looks better now.

Many thanks for your help

Marta

Can I ask if the images have transparency? It looks like the background of some 
images is opaque - and then with the images are drawn (in the draw order 
defined by the layer group) they overlap. You can experiment with the draw 
order to confirm this.

You can actually get more fine grain control if you set up your images as a 
single image 
mosaic<https://docs.geoserver.org/latest/en/user/data/raster/imagemosaic/configuration.html#index-and-configuration-file-creation>
 (including the ability to mark "white" as a transparent). It is okay that the 
individual images are in different projections.

Hi List,

We are having a problem with our geoTiFF images. We have one image for each 
island, some are in epsg:5015, other in epsg:5014. Everting works fine with 
each single one but when they are all together in a layer group with CRS 5013 
defined, some parts of the islands are “cut” at a specific zoom and position 
(picture 1). In picture 2, I change the positon of some island to get them 
right.
Can you help me to solve this situation?

Best Regards,

Marta
