Global Mapper v25.0

How can I import csv data into an existing polygon shapefile using shared sample ID?

I have an existing shapefile of watershed polygons. Each polygon is identified with a unique sample number. How can I import water chemistry values (+25 elements) into the shapefile attribute table from a csv file (each sample has the same sample ID as the corresponding watershed)?

Thank you!

    Hi Jeff,

    You can right-click on the loaded layer in the Control Center and select the Layer->JOIN menu option to join attributes from a CSV file in to the layer.
