I did.....I divided a map up and made a scale...So when I work on each lot I know how many sqaures to move before making ravines and what not.....Each one takes 20min to a few hrs. The map above is only SW Edmonton.....I have alot of the city to do...away from the river valley the city doesnt gain much hieght. But in SC terms to get a road out of the valley you have to make it 13 sqaures long.....To give you a bit of scale. Edmontons river valley is the largest area of parkland in a city and is 21 times the size of central park!
