I use a GeoServer.
I want to create a layer from a mosaic that I got using gdal from a vrt file that is created from pieces of a map whose size is 9 000 000 * 3 000 000 pixels.
To create a VRT file, I use gdalbuildvrt.
gdalbuildvrt file.vrt /*.tif
I plan to use gdal2tiles to create a mosaic.
This layer will only be displayed on a single scale that covers a small number of mosaic granules.
The problem is that if I change one piece of the original map, I will have to redo the entire mosaic, which will take a long time.
here Overviews: to tiles or .vrt, or both? this question was discussed, but I didn't understand how to do it.
Creating overview images for individual rasters becomes more flexible when the layer is partially updated. How?
Is it possible to create a virtual mosaic from virtual VRT files and connect it to GeoServer?
