Hello,

Does anyone have any pointers about how to go about overlay the maps I am 
creating on OpenStreetMap data? I envisage being able to set the 
opacity/transparency of the higher layers so that it is possible to view the 
underlying OpenStreetMap layer more or less clearly. I have both raster and 
vector data layers to display. I was thinking to perhaps provide a slider 
control for the opacity/transparency, but for the time being I'd settle for 
setting a value. Also, for the time being, I am primarily producing static map 
images for a specific area, but I am also thinking about a more interactive 
visual display for interrogating data for this area.  I was thinking that the 
most sensible thing to start with would be to download some OpenStreetMap Data 
and some styling goodies and work from local files rather than pulling in data 
across the web. Once I can display the OSM data on its own, I can then figure 
out the overlay part.

Thanks in advance,

Andy
