  1. The best available source to derive the smooth and better accuracy digital elevation model is ALOS ( Advance Land Observatory Satellite ) images where you can get get the more detailed dem with accurate contours line .
    Though the accuracy some time depends on others factors as well because of the terrain conditions ,some time different project require different kind of digital elevations model where certain other sources are require to derive the model for the respective accuracy .
