Hi all,
Apologies if this is in the wrong thread. I'm new to ArcGIS and a project has landed on my desk. I need to map xyz bathymetry data.
The files have the following extensions.
*.dat
*.ddf
*.des
*.dfn
Does anyone have suggestions as to how to get these files into Arcmap 10.1?
Do I need to take the dat file and convert to csv or txt and use add data xy?
The files are huge with over a million points...
Any help would be greatly appreciated.
Best regards
