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.
