i am using ArcGIS 10.3.1 and working on TIN generation for entire H.P(India).

I have downloaded DEM & generated TIN but it is very slow and when I am doing anything the entire TIN starts forming again and it is taking a lot of time. I have tried many options like started working on geodatabase , done some system setting but still the problem exists.

My system is 8 GB RAM and also have dedicated & 2GB extended graphics. I have tried opening in ArcScene for 3D view but it is only processing and after sometime it stops.

I am unable to do any analysis. I don't know how to proceed.

Does anyone have a solution for this issue?

ArcScene has some limitations, although I think the link I am providing is for x86 systems. From personal experience you cannot load large TINs(> 1GB) into ArcScene/Desktop and visualize, but you can load them into Pro. I have managed to load 4GB TINs into Pro with around 60 millions nodes. You should know that Pro requires quite a lot of resources.I have 32 GB of RAM, a Ryzen 1700x and a 6 GB 1060 and sometimes it feels it's not enough.
What you can do is to cut the TIN into smaller pieces using Edit TIN or Extract TIN.One alternative would be to use Decimate TIN Nodes but you lose on precision here. Another thing I managed to do is to load the TIN directly into the tool you want to use, without prior loading into Desktop/Scene, but this does not work every time.

  • hi thanks for replying me back. I can see that my size of tin is about 1.36 GB.May be this will be the reason. I just wanted to know if I want to analyse the elevation data of the entire area in 3D then it is possible in pro? what is the possibility of such analysis in Q GIS. Please suggest. – masoom khare May 6 '17 at 15:21
