Hi all,

We are planning to use GeoServer to store and publish a high number of GeoTIFF raster files (more than 1 million). What should be the prefered physical storage (File System, Cloud storage, PostGIS) ? the prefered stores and layers types to use ? the prefered plugins and configuration ?

Any feedback is welcome ! Thanks in advance.

Hello Guillaume!

Difficult questions. The complete answer will depend on different parameters:

  • What kind of information is contained in your geotiff? Photos? Basemaps like IGN SCAN 25? EO data?
  • What do you want to do with it? Broadcast them with WMS? Publish them with WCS?
  • How is deploy your GeoServer?
  • How the different geotiff are related together? Do they compose a mosaic? Are they different version of the same area at different time?

I think that the pgraster module is no longer published due to a lack of maintainer so I won’t go this way. The mosaic plugin is often a good start and you can also have a look to the image pyramid plugin.

Regards

Alexandre

Hello !

The information is RGB view of small areas of interest produced from Sentinel data.

We publish it on WMS to integrate in maps in our web applications.

For now, the GeoServer has fully standard deployment (standard docker image, data on file system, with GeoTIFF format).

The different GeoTiff are not linked for now, but yes, for each area of interest, we have a serie of GeoTiff (for several dates of the year).

I will check the mosaic and image pyramid plugins, but if you have more advice, you are welcome !

Regards,

Guillaume
