[Tilecache] Some definitions

I have read both of them.
They gives foundation concepts such as Scales, Projections and explored 
Desktop Applications such as Quantum GIS, uDig and some web technologies.
But they are not the manual of practical open source GIS solutions, such 
as how to combine MapNik, Tilecache and Openlayers to setup map tile 
rendering and something like how to calculate correct Min and Max scale 
denominators for MapNik to be compatible with different OpenLayers' zoom 
levels.

I admit I still don't fully understand the projections, but I get the 
concept and usually use
http://spatialreference.org/ to find or translate SRS from one format to 
another (example WKT to Proj.4).

Cheers,
Thar Htet
