@geographika I saw that part. The full approach goes through the last step of serializing the vectors to the tiles. For this particular map they chose not to, but the same creating levels for every zoom level applies. Let me clarify my answer.

comment Can I change the GDAL/OGR library that QGIS uses?
I cannot remember the exact location since I did it on a different machine that I do not have access to... but you can just download OSGeo4W, install qgis, and under the advanced section of the installer you will find a filegdb ogr driver. Search for files called filegdb - you should only find two - and those are the two places where I added them...

just my new dll and an extra non-gdal dll that I was using for my driver. I can read and write filegdbs from my QGIS without a problem - no changes needed from their end

@Kirk JS itself is also transmitted from the server :) So no advantage there. The size of the fake images are so small, that looping through the pixels in js is notan issue. In fact, the HTML5 implementations in some browsers are hardware accelerated (for example, IE uses DirectX for some features like canvas). The real performance penalty has always been bandwith (i.e data transmission).

@Kirk I could have cleaned up my answer a bit. I just wrote it as it came to me and hit post. Sorry :(

You could do this with Silverlight or Flash for sure. Nevertheless, remember that the important part is happening on the server so Flash or Silverlight would not be of that much of a help.

As far as QGIS, the answer is a bit more involved, I will update my answer on the way to work. Dont freak out, I take a train, so no driving while replying to GIS.SE for me :)

So far, every single person that I have seen using this technique has not posted the code. IMHO, because the important part is really happening on the server and there is no "standard" for this and because choosing what each pixels means (1=sold,2=avail,etc) is so specific to your current map that this code is most likely not "generic".

Great. Have you tried it yourself?
