comment How to convert a JPEG to GeoTiff using FME?
I was looking for a way to take JPG (no geo reference) and convert it to LL84. This helped a lot. All I needed was to use the coordinatesetter and the rastergeoreferences. Thank you.

comment PostGIS convert GeoJSON to geography
Are you saying that ST_GeogFromGeoJSON is the same as: ST_GeogFromWKB(ST_GeomFromGeoJSON(...)))? [assume the JSON is only polygons in EPSG 4326 format]

BTW, FME 2014 (in beta) is going to have a Mapnik renderer. This is great for performance, since one can first create the tiles, then render the clipped OSM data to each tile/zoom pulling data strait from the PostGRE/PostGIS DB.
