Yes, Z/X/Y is generated fine, the problem is the georeferencing of the coloured image. In the link you posted they show that a TIFF can have associated spatial metadata but I'm not sure as to how to Style GeoTIFF (e.g. in QGIS) and then save as a high quality georeferenced TIFF.

Thats's exactly what I want to know. To have them (google vs my tiles) match, all I need is EPSGs to be the same at the moment of tiling? A grand problem is that PNGs are not really georeferenced as is. So I think an additional step is needed to produce a colored image which can be tiled appropriately.

comment Extracting the pixelwise proportion of classes of a finer raster in a coarser one
It's going very very slow but getting there. One question, how does this process handle the projection, extent, etc of the output raster? What I'm worried about is how am I going to align the output raster to my original 1km raster? (30m and 1km are in have same projection).

It's running, ill let you know if it turned out fine, thank you. By the way gdal and numpy dtypes don't get along so well so I had to modify the code where you write the bands to disk: selection = (class_ar == class_ids[bidx]).astype("u1") band.WriteArray(selection)

I use QGIS generally, don't have access to a ArcGIS license. It would be nice to know how to do this in QGIS if it is as easy as you mention but since I will perform this many many times I am interested in the automation of the process.

How can I post data? I think it's quite big. Is it allowed to link to dropbox or something? I don't have arcgis, would it be really hard to implement it in python as is? Sorry for being so picky.
