  6. Digitizing tips • Don’t delete a polygon • You’ll leave a hole • Don’t double digitize a line • If you do, you’ll make slivers • Don’t click and drag polygons • You’ll make gaps and overlaps • LC_name • If no polygons selected • Don’t use field calculator

  7. Digitizing tips • Do edge match with your neighbors • Agree on code/name • Do re-calculate geometry (acres) • After editing polygons • Do check spelling of LC_names • Do separate each annual crop field • Separate polygon • Do download 1939 aerial images • One for each section
