Answering a few comments in one reply here:
Choice of software:
I am aware that Zoomify does this sort of thing too. But I chose krpano
viewer as I already had a license. It is not the cheapest viewer if you
just want to present flat images, but I primarily use it for my panoramic
tours (as example here which has hotspot links to other caves if you want
to explore a bit http://wscc.darkgem.com/footleg/pano/Risco.html )
How the composite map was produced:
The presentation was generated from one very high resolution bitmap image
which I assembled from various bitmaps of the different surveys at
different resolutions using Adobe Photoshop. I started with a high
resolution bitmap of the entire system centreline (printed from Survex to a
PDF and then converted to SVG using Inkscape. The SVG was then imported and
rasterised in Photoshop. I then drag and drop (from the file explorer) each
additional survey bitmap into this Photoshop project, which creates smart
object layers. These enable me to scale/rotate/position each bitmap over
the centreline. Some of the older surveys needed to be stretched a bit to
fit. I made the joins as neat as possible using layer masks to control
which parts of each bitmap are visible over the underlying layers. I can
easily add new surveys into the mix now as I draw up more of the system.
The Therion output was taken from the PDF generated by Therion, and saved
as a bitmap using Inkscape. I could possibly get better conversion quality
by converting to SVG and rasterising that in Photoshop instead. Finally I
export a single flattened TIFF file of the composite map and drop that into
krpanotools, which generates the multi-resoution tiles and HTML5+Flash web
output which I put online.
