I have been given some LiDAR that needs to be processed. The file-type is .xyzi, which I understand to be ASCII. Doing a little bit of research directed me to the ASCII 3D to Feature Class. My assumption is that it needs to be brought in as point features and that then I can interpolate those points into a TIN, which I can then be processed into a DEM. Is this the best way of going about this?
