Replying to [comment:5 jng]:
> Is the issue basically when going through the "pyramid" of tiles to
generate, MgCooker is starting from the bottom instead of the top?
I don't understand exactly what you mean.
If I understand you, then this is the answer:
It doesn't matter where MgCooker starting the generation, bottom or top.
With the above example
With 1:90000 scale:
- MgCooker using scaleindex=0
- MapGuide using scaleindex=9
With 1:250 scale:
- MgCooker using scaleindex=9
- MapGuide using scaleindex=0
Another example:
I generate tiles with MgCooker in 1:8000 scale (and only this scal),
it generates tiles with scaleindex=4.
MapGuide using scaleindex=5 for 1:8000 scale.
Therefore when I view the Map in 1:4000 in Viewer (Fusion), it drawing
1:8000 tiles to the left-top corner (of the entire map) and start to
generate the remaining tiles in 1:4000 scale (which are not found in the
TileCache). (I will attach a picture about it soon.)
