Is it possible to create a DEM from a TIN? If so, how? I'm using ArcMaps 10.2.2. Thanks
Well I was hoping to get something a little more detailed. But then again, I've only got 146 points that I obtained using a differential GPS. What I've got now does resemble the mountain I've surveyed, but it is lacking in detail. I do intend to go back out and take more points. I assume this will give me more detail. Yes? I created a TIN and it seems to be more detailed. Essentially what I'm doing is creating a 3-D map of this mountain in Peru where some archaeologists are excavating. This professor wants me to create a DEM of the excavation site, but the more I read into it, it seems that a TIN may be the better option. What she is going to want is detail, as much as I can get. I'm just a student, so I'm still learning this, so please bear with me. But a TIN would be a form of DEM in essence, no? I mean it is showing relief, it's three dimensional, so I imagine either would be good for the project, it's just a matter of what is more presentable I suppose. Any thoughts? Once again, thanks.
The raster you created from the TIN will probably be the DEM (Digital Elevation Model) and allows for many different spatial analysis. What other tasks do you set? Or in other words, what do you want to achieve?
Thats it.
Since your TIN is derived from elevation data, the raster values are elevation values, so thats a DEM.
Okay, great, done! So what next?
Try the TIN To Raster (3D Analyst) tool. You will need access to the 3D Analyst extension
