let's see. First, I would not store 100k raster points in the relational table
as its terribly inefficient. We do have input data formats, though, which are
similar to what a PG dump of such a table would deliver. We import this into an
array and then can query it. Import via rasql or through an import tool which
internally generates rasql calls.<br>
<br>
Then, for corner points (x0,y0) and (x1,y1) we retrieve as<br>
<br>
select png( M[x0:y1,y0:y1] ) from MyMap as M<br>
<br>
...in PNG format via the rasql cmd line utility or the C++ or Java API.<br>
<br>
Alternatively, sending this this query over the API gets you the data into main
memory ready for nested for loops = in the main memory format of your client:<br>
<br>
select M[x0:y1,y0:y1] from MyMap as M<br>

<p class=MsoNormal style='margin-bottom:12.0pt'>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">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>

said the png was working. Now it’s not? Did you try gdal_translate with the
ESRI grid? For sure I haven’t test yet with such big rasters. Is this the
result of a merge or all your original raster are all this size? The point is
that with WKT Raster you don’t have to merge your raster first into a gigantic

<p class=MsoNormal style='margin-bottom:12.0pt'>Hi All,<br>

Note: As Gdal works fine.<br>
