hi,
it is better to use ur mass points for generation of
TIN. your contour, if created from the same set of
masspoints, creating a TIN from that is not of any
use. if ur contour source is something else other than
these masspoints and if it is more accurate, it is
better to use the contour for TIN.
But to create a perfect TIN (representation of
surface), both contour lines and mass points (which
may appear in between the conotur lines) can be used.
When you use, contours, ur TIN file size will be
larger comapred to creating the same from Masspoints
only
Regards
Jay
