Hi, I want to use 3 different series of Data in the form of TIN for a viewshed analysis. I thought to convert them to raster because as I saw, I cannot do a viewshed in the form of TIN. My problem is that when I convert TIN to Raster from the 3D Analysis toolbox, although the resolution in TIN is 10meters, in Raster is almost 30meters. Why is that? Can't i convert it to raster and to have the same resolution? The analysis at my raster is being made for 30 meters resolution or for 10 meters at last?
Thank you very much
Yes as I stated earlier. The link to the help topic is in your viewshed thread.
Hi Kon,
Did you try changing the environment setting of the tool?
Yes, the default were the numbers I wrote above
Kon,
If you are still having this issue, maybe you would consider uploading one of your tins so that we can better understand what is happening here.
Luke thanks for your interest. I don't have that issue, i just put the resolution i wanted at the cell size. My wonderies are just when I have a TIN from 10 meters resolution elevation data, and I create a raster from that TIN with resolution bigger than 10 meters, for example 1meter resolution (that I define every time), what are the restrictions of that step, you know the theory. This is mainly my problem, the theory beyond that. Thanks a lot.

In either case, either data structure is only as good as your input data, and that includes considerations of accuracy and in the case of precision you also need to look at spacing between the intervening point (if variable), the type of interpolator or aggregator in the case of rasters.
