I have a raster layer of about 30 tiles. The rasters overlap and important data is hidden when the tiles are displayed as a layer. I'm wondered how others get around this issue? Can geoserver let users switch on and off individual tiles in a raster layer?

Adding to @IanTurton's answer, you can also pass in a CQL_FILTER filtering on top of whatever attribute you have in the image mosaic index.

Maybe, it depends on how you would like them to be able to choose.

If you can specify a specific variable that users could use then probably yes. The standard variables are TIME and ELEVATION, but you can specify a custom dimension too.

If you just want them to be able to select an arbitrary raster then I'm afraid the answer is no.

    Thanks. The users will be loading the layer in ArcMap and would want to be able to single out a single image at a time so as not to miss any information obscured by the layer. One option in Geoserver is to create 30 layers of 1 tile. Not very elegant but perhaps that's the only way.

  • @Neil Did you ever find a better solution than creating 30 separate layers?

  • Sorry, i don't think I did. It was for a temporary project, now completed.
