Summary

Converts a raster to a triangulated irregular network (TIN) dataset.

Usage

  • Converting a raster to a TIN will not, in and of itself, produce a better surface. You need ancillary data that's compatible with, and improves, the surface definition. Such data could be added to the TIN using the Edit TIN tool.

  • The default maximum allowable difference between the height of the input raster and the height of the output TIN is 1/10 of the z range of the input raster.

  • While the maximum size of a TIN that can be used under Win32 is between 15 to 20 million nodes, it's recommended to cap the size at a few million. Large input rasters, and small z-tolerance settings, may exceed this. If size is an issue, consider processing subsets.

Parameters

LabelExplanationData Type
Input Raster

The raster to process.

Raster Layer; Mosaic Layer
Output TIN

The TIN dataset that will be generated.

TIN
Z Tolerance
(Optional)

The maximum allowable difference in (z units) between the height of the input raster and the height of the output TIN. By default, the z tolerance is 1/10 of the z range of the input raster.

Double
Maximum Number of Points
(Optional)

The maximum number of points that will be added to the TIN before the process is terminated. By default, the process will continue until all the points are added.

Long
Z Factor
(Optional)

The factor that the height values of the raster will be multiplied by in the resulting TIN dataset. This is typically used to convert Z units to match XY units.

Double
