I have taken the new heightfiles from Nick's dev site - and used them with
my modified code to generate panoramas. I've posted the results on the wiki.
I'll post the full source code there if anyone is interested.
There are, however, some heightfiles missing from the full set. There are no
heightfiles with the name XX99 e.g. on the wiki, I've given an example
showing that SJ99ne, SJ99nw, SJ99se, SJ99sw are all missing. This is true of
every OS grid square - so full 100x100km OS grid squares fully on land only
have 396 5x5km files, instead of 400.
Also, OS grid squares HP,HT,HU,HW,HX,HY & HZ are also missing. These only
cover the Orkneys & Shetland & islands off the Scottish northern coast, but
I'm sure someone will find them useful if they were present.
