Hi list,
I am asking permission to replace the old arcgrid plugin to read ascii
grids in esri and grass format with the brand new implementation tha
actually reside under spike.
There are two pieces of it, as the effort to produce decent coverage
plugins requires:
1>the real imageio plugin that does all the I/O
2>the geotools coverage plugin that relies on 1 for I/O but add
georeferencing information on to of it.
My plan is as follows:
1>Upload the imageio plugin as a jar file.
2>Put a dependency from the above jar in the new arcgrid geotools plugin.
3>Completely replace the old geotools arcgrid plugin with the new one.
4>Add this plugin to geoserver-raster.
What is missing on this new plugin:
-ability to read directly from gzipped files
The reason of this is that first of all it is really counterproductive
in terms of performaces and also is a pain to integrate this
capability with imageio (I could do it, but it is really low low low
priority for me).
What we are going to gain:
-performances
-tiling native
-performances
-decimation on reading (nearest neighbohr subsampling from disk)
-performances
-clean separation between raw data I/O and metadata I/O
-performances
Cheers,
Simone.
