Posting back! The txt2las.exe worked great! Got the las to a dataset and from that the "Las to Raster" tool. A problem remains however - the "Las to Raster" interpolated inside island areas aswell and i was unable to set a boundry or extent to which i wanted interpolation to be done. The quality of the interpolation seems very good, but i see that the scale begins from -0,2 so it interpolates land at some part. It is small, but i'd like to get a more specific interpolation. Any tips on that would be greatly appreciated!

Hello! I've recently been working with some large .xyz data, about 1,2 gb worth. So far i've managed to get the points into ArcMap with the "ASCII 3D to Feature Class" tool. With a fraction of the data, i managed to create a tin and then use the "Tin to Raster" tool and got good results. ArcMap even processed the entire area to a tin file, about 2,7 gb, but was unable to display it (error about lack of memory) and even use it for the "Tin to Raster" tool. I have thought about manually splitting the .xyz file to smaller portions and go with the "Tin to Raster", but there are still some issues i need to work around. Firstly, the coordinates are depth points for a sea area around a large coast. Because of this i need to add some-kind of coastline reference to ensure that all interpolation reaches 0 z-value at the coast. Secondly, if i partition the .xyz data to smaller groups, i'm afraid of getting artifacts at the breaking lines, which would ruin the end product (after merging the raster). So far, i've been unsuccessful at finding a solution online. Any help would be greatly appreciated! All the best, Sander Paekivi
