We recently subscribed to the service to access sentinel images in a WMS/WMTS stream. It works very well, but we still encounter some problems. Indeed, we would like the WMS to match the latest SENTINEL images. It seems that this is the case when we are zoomed out but as soon as we zoom in another less recent image appears (see image below). How can we fix this problem?
it seems that the
time parameter is not set optimally.
If only a single time point is specified, the service will return a mosaic of the images from the beginning until the specified time point (beginning = the earliest time for which the data is available for a selected dataset). This can vary between zoom levels.
If two time points (start and end of the time range) are specified, the service will return a mosaic of the images from that time range.
To get the image of one day, the date (or time) should be set as start and end of the time range (

time parameter and other WMS parameters available here.
Hope this helps.
