During the 'communications weekend', Andrew found a small program called CanalCalc, which offered to produce timed listing of journeys between specific points on the canal network.
However, it is rather old and its owner SteveT no longer maintains it. nevertheless, the idea seemed interestign, especially as we have already scanned in a number of the mileage charts.
Detailed investigation showed serious flaws in CanalCalc, principally as the locations of points on the network are determined by distances given to the nearest tenth of a mile. Over longer runs, the erros can build up to be significant.
Hence, today, I decided to spend a little time producing at least a prototype edition of an improved version which alloows for greater flexibility and accuracy. It should also allow for places to be given a geographic location - the interesting bit would be to explore the possibilty of a mash-up with Google Maps!
Although we were out this afternoon, a good start has been made with basic structures and functions now in place. Hopefully, tomorrow will provide sufficient time to create a tolerably useful version - perhaps we can add some locations as well. A schematic map would be good as well!
