Esri TIN elevation interpolation methods.
| Constant | Value | Description |
|---|---|---|
| esriLinearInterpolation | 0 | Uses linear interpolation. |
| esriNaturalNeighborInterpolation | 1 | Uses natural neighbor interpolation. |
| esriNaturalNeighborZmin | 2 | Uses the minimum Z of all natural neighbor nodes. |
| esriNaturalNeighborZmax | 3 | Uses the maximum Z of all natural neighbor nodes. |
| esriNaturalNeighborZaverage | 4 | Uses the z closest to the average of all natural neighbor nodes. |
| esriNaturalNeighborZnearest | 5 | Uses the Z value of the nearst node. |
| esriNaturalNeighborIDW | 6 | Uses 'Inverse Distance Weight' based on natural neighbors. |
