Why You Might Want to Use a TIN
GRID
- Data redundancy in areas of uniform terrain
- Inability to adapt to areas of differing relief complexity
- Exaggerated emphasis along the axis of the grid
TIN
- Non-redundant data
- Allows extra data in complex areas and less data in non-complex areas
- The ability to use natural features as break-lines
- Of course, you have to like triangles
