I have deployed two pan-sharpened raster from Pleiades imagery covering different areas with an overlap. Individually they are opaque (see here and there) but when inside a layer group (with default settings), they turn approx 50% transparent and it seems there is nothing you can change (see here). If alone in another layer group the raster are displayed without transparency (see there). It seems this is a because there is a overlap. Is there a way to solve this in GeoServer or is it mandatory to cut the imagery in order to have no overlap at all?

EDIT : adding a screenshot of one of the layers settings: screenshot

and another screenshot regarding the layer group settings: screenshot

  • Please add screen shots rather than live links, we also need to know how you have styled your rasters.

  • Thanks for your answers Ian. Basically what I described IS what I have done: two raster as layers in GeoServer and a layers group with he two layers together, what my links point to. I thought it was better to show them this way than with screenshots in order to allow zooming in and out. I have not styled these raster, the settings are default. Based on this, I rephrase a bit my question: is there something to be set in GeoServer to solve this default transparency, or do I need to do something on the raster themselves (I suggested to cut them in order not to have any overlapping) ?

  • I figured out you were talking about settings screenshots, my bad. I edited the question and add two, if other ones would be helpful, just tell me.

  • Actually, I meant the maps them selves but never mind. What styles are you using? Have you considered using an image mosaic rather than a layer group which was not really designed for this
