I'm almost a beginner at PostGIS and GeoServer so I hope you could help me with my question.

In my PostGIS database I have a lot of GeoTIFFs that I would like to display in a WebGIS via GeoServer and OpenLayers3.

Every hour a new GeoTIFF with temperature information is coming.



INCA-T2M_20160614T1500.tif etc.

I upload them via raster2pgsql into the database. There they have the columns rid, rast and filename

Now I would like to build a query in the WebGIS where the user could type a date and time and the suitable GeoTIFF will be displayed. Therefore I have to build the correct WMS request with OpenLayers3 and send them to the GeoServer. But how does the correct WMS-request looks like and how the GeoServer will ask my database for the correct table?

After reading the GeoServer documentation maybe the creation of an sql view with parameter could be the solution?

The examples here are dealing with the selection of a specific range of data from a fix table. But I don't know how do I have to build a query to ask for a specific table, not for a range of data in a fix table.

But maybe I'm on a wrong path... Do you have any idea?

  • Have a look at docs.geoserver.org/latest/en/user/tutorials/… - it's all built in except keeping rasters in postgis - use the disk instead much quicker. – Ian Turton Jan 23 '17 at 11:52
  • is the XY extent the same for each raster, just time and temperature changing? if so you consider a web coverage service (WCS) solution instead of a WMS. – nmtoken Jan 23 '17 at 11:58
