My professor (who is now unreachable on holiday) gave me files to work with for a mapping project. The files were retrieved from the Ordinance Survey Ireland webpage. They were used to differentially correct GIS data that had been collected in the field.
I don't recognize the file format, and I am unsure how I am meant to interact with these file types. The files have suffixes like .18N, .18G, etc. I have attached a picture. What is this format?
How do I use these files?
I'm working with Grass/QGIS.
