[OSM-dev] Cutting up an image into tiles

[Nick Black]

Hello,

I have a TIFF image map of the Isle of Man at approximately 1:25,000
scale.   The IoM Gov have given dervative rights to OSM to use it to
produce data from.  I need to cut the image up into smaller tiles,
which I was then planning on rectifying using the metacarta rectifier,
then using the JOSM WMS plugin the trace the roads.

So can anyone point me in the direction of some guidelines about
scripting ImageMagick / Rmagick , or something the cut the image up -
which shouldnt be too hard to do?   I dont have access to the TIFF
right at the moment, but its big.  Over 80mb I think.
