I have 4 million random tiles split up into subdirectories containing 5000 tiles. The tiles are GeoTIFFs with dimensions of 1536 x 1536. Using gdal, I ingested the tiles into geoserver the following way:
1. Create a virtual dataset (gdalbuildvrt -addalpha my-ds.vrt /tiles/1/*) for each subdirectory. Note the "addalpha" option to ensure that transparent tiles are between the supplied tiles. 2. List all the virtual datasets in a file (all-datasets.txt). 3. Use gdal_retile (gdal_retile.py ... --optfile=all-datasets.txt) to generate an image pyramid. 4. Wait... 5. Create a store, ImagePyramid layer etc in geoserver and view the tiles via WMS. At regular intervals, I will need to add more tiles to my existing dataset. There may be one single tile, or another million. The tiles may also be of variable sizes e.g. 30000 x 30000. My first question is can someone confirm if this is the best way to ingest such a large volume of into geoserver (in terms of efficiency and scalability etc)? My second question is how can I merge/append my new data to the existing image pyramid without having to run gdal_retile over the whole dataset (new and old) all over again? The initial set has taken days to ingest and I want new tiles to be added in real-time as they are made available so users can see the results via WMS. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Appending-large-volumes-of-tiles-to-existing-WMS-image-pyramid-tp5140623.html Sent from the GeoServer - User mailing list archive at Nabble.com. ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
