Part 1. Importing data from GNSS
A common archaeological workflow is to acquire data with a field instrument such as GNSS or Total Station and then transfer the data to a GIS in CSV format. CSV or Comma-separated values, is a tabular format where each position or record is a row, spatial coordinates are stored in two or three columns, and attributes are also attached in the table. This video demonstrates the process of bringing these data into QGIS 3.22 using the Create Features from Delimited Text File functionality.
Closely linked to this process is the units of measure themselves. Should you use UTM or Decimal Degree, or an arbitrary site-specific coordinate system not connected to real world units? What datum and coordinate system is best for site level data?
