Spatio-temporal raster

[Vittorio Maniezzo]

Now I have a series of images of the same area taken in successive days, and I'd like to do something like computing an average of the pixel of one same subregion across a time-defined subset of the images (say, all the last month images).
Any better way than uploading a raster for each image? How could I select all rasters within the time interval?
Thanks,

Vittorio

Are you sure that you sent this message to the right forum?

- this sounds more like a gdal question (assuming the rasters are georeferenced)

Well, I'd like to use spatialite to do the work (as I am doing now). And yes, raster are georeferenced.

I think it sounds more like an array processing problem where something like Numpy would be better suited.  Gdal or Rasterio could help with getting the raster data into numpy.  Out of the box Python functionality could handle the image file management.
