As you see, slicing in all 3 dimensions delivers roughly the same times
(although tiling has not been optimized).<br>

it's a XEON. Your question comes at the right time, we are in the
process of compiling performance data this summer. I will soon post
detail info here.<br>
<br>
Loading 100k x 150k pixels is no problem. You load piecemeal, and the
system will align with its internal tiling + maintain the image
pyramid. <br>
<br>
10 years back we have loaded the whole ortho image mosaic of Bavaria
into the database (server was a desktop PC of about 1000 EUR), that was
600 GB compressed (losslessly). At that time, import of an 230 MB image
took about 2min (array placement, re-tiling of input, index
maintenance, compression, and this for all pyramid levels). Read
access, OTOH, was about 150ms. A few years later the Thuringia Mapping
Agency, again with a desktop PC as a server, verified that access times
are stable under a load of about 15 concurrent users challenging the
system with WMS type interactive browsing. <br>
<br>
For another mapping agency we have set up a database containing ortho
image, 30+ thematic raster layers, DEM. Access was via WMS, the
rasdaman system delivered a single image for display (Javascript was
not what it is today...). This included on-the-fly classification of
the DEM and styling the thematic layers.<br>
<br>
So we have already done complete raster servers for several German
States.<br>
<br>
BTW, standards: We have established the OGC Web Coverage Processing
Service (WCPS) standard which lifts the rasdaman concept of a raster
querfy language to an OGC standard. Being editor of currently 9 geo
raster service specs in OGC we also pursue reference implementations on
the basis of rasdaman. See <a href="http://www.earthlook.org" target="_blank">www.earthlook.org</a>
for demos.<br>
<br>
-Peter<br>
<br>
PS: Should data really exceed disk capacity (hard to believe today)
then we have a PhD thesis work which has implemented transparent tape
cabinetaccess. <br>

<p class="MsoNormal" style="margin-bottom: 12pt;">yes... with
png
worked... but
it was a different png (a smaller one)...<br>
<br>
so I've converted the ESRI into a png and tried to import it... and it
didn't
work neither... <br>
<br>
so this is the situation:<br>
A have huge rusters (from 150kx150k).. In Oracle I would just load it
(the huge
raster) in a single row of a GeoRaster table and then Oracle GeoRaster
would
split it in small tiles and store one tile per line of another table
(Raster
Data Table)... then I can run a query similar to this one: SELECT
getcellvalue(t.rastercolumn,x,y) from GeoRasterTable t where <a href="http://t.id" target="_blank">t.id</a>=1;
and GeoRaster
will query automatically the
spatial indexes and the Raster Data Table and it will find the right
tile
etc...<br>
<br>
I do not know how WKTRaster works.... If I cannot import a such big
image, of
course I can split it in smaller georeferenced tiles... (how?)...
but.... My
main question is: after that, how will the table look like ? how can I
do the
same query (where id=1 or where name="UK" etc...) ?<br>
