This script loops through all the SRF files in a directory, and exports any contour maps within those SRF projects to Shapefile format.
To run this script:
- Copy the script below, or download the attached BAS file: Loop SRFs export SHP contours.bas.
- In a Windows Explorer window, navigate to C:\Program Files\Golden Software\Surfer 16.
- Double click on Scripter.exe to launch Scripter.
- Press Ctrl+A to select all of the existing lines then press DELETE.
- If you copied this script, press Ctrl+V to paste it into Scripter. If you downloaded it, click File | Open, select the BAS file from your downloads directory, and click Open.
- Change the file path, output file name, and data file extension in the User-defined variables section at the beginning of the script.
- Click Script | Run to run the script.
