I am trying to create a terrian from the geometry that i have for 1D . I have the stations and the elevation and i would like to create a terrain out of it by interpolating the cross section that i have . I tried to use ras mapper but i am not able to get a good terrain. when a run a terrain obtained from the RAS mapper it flows like overland flow and make no sense at all . Any one could give me a suggestion. I would really appreciate your help .
