Extracting elevation values from a TIN to a polygon or raster
I am having trouble figuring out how to extract averaged values from a TIN to a created polygon grid. I see that in Spatial Analyst i can extract values to points, but not polygons. I also have access to 3D Analyst if I need that.
Mapping Center Answer:
There are a couple of tools that can help here. First is the TIN to raster tool, and the second is the Interpolate shape tool. Both of these tools are in the 3D Analyst extension. The TIN to Raster tool will handle turning your TIN into a raster. Then either the TIN or the raster can be used as in put to the Interpolate shape tool. The results will be a bit different, so I would recommend trying both and choosing the result that best suits your purposes.
I'm not sure I interpretted the question fully, another possibility is that you want to use the TIN Polygon Tag tool, which is also in the 3D Analyst.
