I'm still working on some various methods for extracting time series data
for a specific point out of an Image Mosaic data store. One of those
methods is a custom ows I have written that ultimately uses the
GridCoverage2DReader supplied by the CoverageInfo in the Catalog.
I have it working, but it is slow. It is slow, I believe, because I am
calling a read on the reader for every time desired (i.e. setting the
ImageMosaicFormat.TIME parameter and calling read). This, in turn, causes
the ImageMosaicReader to re-search for valid granules at each time step ...
causing db connections to be opened ... queries executed ... connections
closed ... etc. ... and this gets expensive.
My question, then, is there any way I can simultaneously supply ALL of the
desired times in the parameters provided to the reader and have it return
data for all of those times with ONE read call, thus only needing to
produce the mosaic once and avoiding the expense of re-producing the mosaic
for each time step?
Is there a different way to accomplish this, maybe?
Thanks,
Mike Grogan
