The TIN Operations Dialog allows you to carry out several operations based on TIN models including:
Drape Selected Features
This operation sets the elevation of the selected features to the corresponding elevation on the TIN surface.
Create TIN Boundary Feature(s)
This operation determines the current extents of the TIN model and creates corresponding feature(s).
Create Watershed Features
This operation determines the catchment areas of the TIN model and creates corresponding features.
A catchment area (watershed or drainage basin) is defined as an area of land where precipitation collects and drains off into a common outlet, such as into a river, bay.
The automatic calculation of watershed areas is based on a regular grid. The user can choose the grid Cell Size.
A Depression Fill Depth parameter is used to smooth the surface by filling minor depressions(prior to calculating the watershed features).
Create Drainage Area Feature
This operation determines the drainage area associated with a specific point creates corresponding feature.
