The purpose of the Raster To TIN tool is to create a triangulated irregular network (TIN) whose surface does not deviate from the input raster by more than a specified Z tolerance. Create lines and polylines from raster images, and convert raster files into vector drawings. Raster Analysis Moving windows and kernals can be used with a mean kernal to reduce the difference between a cell and surrounding cells. Raster grids in ArcGIS need to use integer or floating-point values for the "Value" attribute in the raster attribute table. The Field parameter allows you to choose which attribute field of the input raster dataset will become an attribute in the output feature class. From Tuflow.
