Geoserver: Time Slider for ImageMosaic Plugin for raster time-series data

Background:

I am new to geoserver and the 'ImageMosaic Plugin for raster time-series data': I followed the tutorial on this page and managed to upload a raster time series to my local geoserver, which works pretty nice. I can access my single layers by changing the extension in the url like this:

&time=2009-10-01, &time=2009-11-01 and &time=2009-12-01

enter image description here

Problem:

What I want to do now, is to make a JS/jQuery time slider, that refreshes my page/map when the slider date value is changed by the user and in a way that the corresponding raster image is loaded. Right now, I have three images in my series. To code a slider for those three raster files is not a problem. But if I will add another raster file to my time series in the future, I will need to also update my slider. Is there any way to code the slider dynamically?

In other words, can I send some kind of request to my geoserver that returns the number of raster layers in my ImageMosaic and also their dates, so I can use this information when the slider is loaded and generated?

Solution

  • As an administrator you can query the underlying index with a recent geoserver. See this page.

    An alternative is to perse the GetCapabilities document and look for the TIME dimension values. You might want to fiddle with the Dimensions tab in GeoServer.
