If you have access to the 3D Analyst extension, this can be accomplished using the TIN Node tool found here: 3D Analyst Tools - Conversion - From TIN - TIN Node. This will create 3D points (i.e Z-enabled) at each triangle node that forms the TIN. Alternatively you could convert your TIN to a raster, and then use the Raster to Multipoint tool which will ...

This is fine, everyone has to start somewhere. But if you really want to learn the proper methodolgy, you're going to need to do some research into all the various steps, even just to get an overview of ...

I would take a step back and ask is my GPS capable of making a DEM. The answer to this question for most consumer grade units is unfortunately no, well not without quite some work before you start interpolating etc. The vertical error in GPS can be very large even with modern units. What you are measuring is also an issue, see below. "A brief examination ...

starting from points to build a continuous surface is called spatial interpolation. You can find information about those methods on the Web. Surfaces can be represented using wo different models : raster or TIN. Most existing DEMs use the raster model, but TIN is sometimes a good alternative. As its names says, TIN are composed of irregular triangles, ...
