Topography and geology
Topographical data should be available, and just letting people wander over simulated hills and valleys might be educational. (How do you make subtle slopes obvious?) Maybe the 1909 map could be layered onto it. (Is there some toolkit that makes this easy?)
The evolution of the underlying geology might also be of interest.
U19: "He capered before them down towards the fortyfoot hole, fluttering his winglike hands, leaping nimbly, Mercury's hat quivering in the fresh wind that bore back to them his brief birdsweet cries."
U93: "The carriage climbed more slowly the hill of Rutland square."
U168: "Hidden under wild ferns on Howth. Below us bay sleeping sky... High on Ben Howth"
U236: "John Wyse Nolan, lagging behind, reading the list, came after them quickly down Cork hill."
U265: "Slower the mare went up the hill by the Rotunda,"
U328: "Tarbarrels and bonfires were lighted along the coastline of the four seas on the summits of the Hill of Howth, Three Rock Mountain, Sugarloaf, Bray Head, the mountains of Mourne, the Galtees, the Ox and Donegal and Sperrin peaks, the Nagles and the Bograghs, the Connemara hills, the reeks of M' Gillicuddy, Slieve Aughty, Slieve Bernagh and Slieve Bloom."
U624: "From Roundwood reservoir in county Wicklow of a cubic capacity of 2,400 million gallons, percolating through a subterranean aqueduct of filtre mains of single and double pipeage constructed at an initial plant cost of £ 5 per linear yard by way of the Dargle, Rathdown, Glen of the Downs and Callowhill to the 26 acre reservoir at Stillorgan, a distance of 22 statute miles, and thence, through a system of relieving tanks, by a gradient of 250 feet to the city boundary at Eustace bridge, upper Leeson street, though from prolonged summer drouth and daily supply of 12 1/2 million gallons the water had fallen below the sill of the overflow weir for which reason the borough surveyor and waterworks engineer, Mr Spencer Harty, C. E., on the instructions of the waterworks committee had prohibited the use of municipal water for purposes other than those of consumption (envisaging the possibility of recourse being had to the impotable water of the Grand and Royal canals as in 1893) particularly as the South Dublin Guardians, notwithstanding their ration of 15 gallons per day per pauper supplied through a 6 inch meter had been convicted of a wastage of 20,000 gallons per night by a reading of their meter on the affirmation of the law agent of the corporation, Mr Ignatius Rice, solicitor, thereby acting to the detriment of another section of the public, selfsupporting taxpayers, solvent, sound."
