I have a large number of raster layers for known areas of interest with different measurements for the same area and timestep stored in different files. To reduce the number of layers I've concatenated the measurements for the same area/time into multi-channel layers with different stylesheets to display each band.
So let's say I used to have layers 20190114_BlueCarPark_1.tif,20190114_BlueCarPark_2.tif and so on, I now have a single later 20190114_BlueCarPark.tif that contains each of the old layers from Blue car Park on 20190114. These channels are stored band sequentially to allow channels to be read in continuous chunks. However, I've found that this is causing WMS rendering to be quite a bit slower, my guess is that rather than determining which pixels are required, Geoserver is maybe reading the entire 3-D array from file and then subsetting down to the channel specified in the stylesheet. Is that correct? I'm using the default ImageIO library rather than the extension -- Sent from: http://osgeo-org.1560.x6.nabble.com/GeoServer-User-f3786390.html _______________________________________________ Geoserver-users mailing list Please make sure you read the following two resources before posting to this list: - Earning your support instead of buying it, but Ian Turton: http://www.ianturton.com/talks/foss4g.html#/ - The GeoServer user list posting guidelines: http://geoserver.org/comm/userlist-guidelines.html If you want to request a feature or an improvement, also see this: https://github.com/geoserver/geoserver/wiki/Successfully-requesting-and-integrating-new-features-and-improvements-in-GeoServer Geoserver-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geoserver-users
